BARNACLES: K'WIT'A'A

One of the most interesting and enigmatic little critters we find at the seashore are barnacles. They cling to rocks deep in the sea and at the waters' edge, closed to our curiosity, their domed mounds like little closed beaks shut to the water and the world.

They choose their permanent homes as larvae, sticking to hard substrates that will become their permanent homes for the rest of their lives. It has taken us a long time to find how they actually stick or what kind of "glue" they were using.

Remarkably, the barnacle glue sticks to rocks in a similar way to how red cells bind together. Red blood cells bind and clot with a little help from some enzymes. 

These work to create long protein fibres that first blind, clot then form a scab. The mechanism barnacles use, right down to the enzyme, is very similar. That's especially interesting as about a billion years separate our evolutionary path from theirs.

So, with the help of their clever enzymes, they can affix to most anything – ship hulls, rocks, and even the skin of whales. If you find them in tidepools, you begin to see their true nature as they open up, their delicate feathery finger-like projections flowing back and forth in the surf.

One of my earliest memories is of playing with them in the tidepools on the north end of Vancouver Island. It was here that I learned their many names. In the Kwak'wala language of the Kwakiutl First Nations of the Pacific Northwest, the word for barnacles is k̕wit̕a̱'a — and if it is a very small barnacle it is called t̕sot̕soma — and the Kwak'wala word for glue is ḵ̕wa̱dayu.

AN AMMONITE HOSTING WEE BIVALVES

What you are seeing here is a protuberance extruding from the venter of Quenstedtoceras cf. leachi (Sowerby). It is a pathology in the shell from hosting immature bivalves that shared the seas with these Middle Jurassic, Upper Callovian, Lamberti zone fauna from the Volga River basin. The collecting site is the now inactive Dubki commercial clay quarry and brickyard near Saratov, Russia. 

The site has produced thousands of ammonite specimens. A good 1,100 of those ended up at the Black Hills Institute of Geological Research in Hill City, South Dakota. 

Roughly 1,000 of those are Quenstedtoceras (Lamberticeras) lamberti and the other 100 are a mix of other species found in the same zone. These included Eboraciceras, Peltoceras, Kosmoceras, Grossouvria, Proriceras, Cadoceras and Rursiceras. 

What is especially interesting is the volume of specimens — 167 Quenstedtoceras (Lamberticeras) lamberti and 89 other species in the Black Hills collection — with healed predation injuries. It seems Quenstedtoceras (Lamberticeras) lamberti are the most common specimens found here and so not surprisingly the most common species found injured. Of the 1,000, 655 of the Quenstedtoceras (Lamberticeras) lamberti displayed some sort of deformation or growth on the shell or had grown in a tilted manner. 

Again, some of the Q. lamberti had small depressions in the centre likely due to a healed bite and hosting infestations of the immature bivalve Placunopsis and some Ostrea. 

The bivalves thrived on their accommodating hosts and the ammonites carried on, growing their shells right up and over their bivalve guests. This relationship led to some weird and deformities of their shells. They grow in, around, up and over nearly every surface of the shell and seem to have lived out their lives there. It must have gotten a bit unworkable for the ammonites, their shells becoming warped and unevenly weighted. Over time, both the flourishing bivalves and the ammonite shells growing up and over them produced some of the most interesting pathology specimens I have ever seen.    

In the photo here from Emil Black, you can see some of the distorted shapes of Quenstedtoceras sp. Look closely and you see a trochospiral or flattened appearance on one side while they are rounded on the other. 

All of these beauties hail from the Dubki Quarry near Saratov, Russia. The ammonites were collected in marl or clay used in brick making. The clay particles suggest a calm, deep marine environment. One of the lovely features of the preservation here is the amount of pyrite filling and replacement. It looks like these ammonites were buried in an oxygen-deficient environment. 

The ammonites were likely living higher in the water column, well above the oxygen-poor bottom. An isotopic study would be interesting to prove this hypothesis. There's certainly enough of these ammonites that have been recovered to make that possible. It's estimated that over a thousand specimens have been recovered from the site but that number is likely much higher. But these are not complete specimens. We mostly find the phragmocones and partial body chambers. Given the numbers, this may be a site documenting a mass spawning death over several years or generations.

If you fancy a read on all things cephie, consider picking up a copy of Cephalopods Present and Past: New Insights and Fresh Perspectives edited by Neil Landman and Richard Davis. Figure 16.2 is from page 348 of that publication and shows the hosting predation quite well. 

Photos: Courtesy of the deeply awesome Emil Black. These are in his personal collection that I hope to see in person one day. 

It was his sharing of the top photo and the strange anomaly that had me explore more about the fossils from Dubki and the weird and wonderful hosting relationship between ammonites and bivalves. Thank you, my friend!

FOSSIL AMMONOIDS OF NEVADA

Time Slows at Berlin-Ichthyosaur State Park

Around half past five, as the first flush of dawn appears, our group was up and ready to visit a site that has been on my bucket list for some time.

High on the hillside up a long entry road sits the entrance to Berlin-Ichthyosaur State Park in central Nevada. It is a short 2-hour drive from our lodgings through orange-hued grasslands and low sloping hills.

A worn American flag and sun-bleached outbuildings greet you on your way to the outcrops. Away from the hustle and bustle that defines the rest of Nevada this place feels remarkably serene. Your eyes squint against the sun as you search for ammonoids and other marine fossil fauna while your nose tends to the assault from the bracing smell of sagebrush.

This site holds many stories. The interpretive centre displays wonderful marine reptiles, ichthyosaurs in situ, as you might expect from the name of the park — but it also showcases years of history lovingly tended. This stretch of dry golden low hills dappled with the yellow of creosote and desert grasses is an important locality for our understanding of the Carnian-Norian boundary (CNB) in North America.

The area is known worldwide as one of the most important ichthyosaur Fossil-Lagerstätte because of the sheer volume of remarkably well-preserved, fully articulated (all the sweet bones laid out all in a row...) specimens of Shonisaurus popularis.

Rich ammonoid faunas outcrop in the barren hills of the Upper Triassic (Early Norian, Kerri zone), Luning Formation, West Union Canyon, Nevada. They were studied by N. J. Silberling (1959) and provide support for the definition of the Schucherti and Macrolobatus zones of the latest Carnian — which are here overlain by well-preserved faunas of the earliest Norian Kerri Zone. 

The genus Gonionotites, very common in the Tethys and British Columbia, is for the moment, unknown in Nevada. The Upper Carnian faunas are dominated by Tropitidae, while Juvavitidae are conspicuously lacking. 

Middle Triassic Ammonoids

Despite its importance, no further investigations had been done at this site for a good 50 years. That changed in 2010 when Jim Haggart, Mike Orchard and Paul Smith — all local Vancouverites — collaborated on a project that took them down to Nevada to look at the conodonts and ammonoids. They did a bed-by-bed sampling of ammonoids and conodonts in West Union Canyon during October of that year.

October is an ideal time to do fieldwork in this area. There are a few good weeks between screaming hot and frigid cold. It is also tarantula breeding season so keep your eyes peeled. Those sweet little burrows you see are not from rodents but rather largish arachnids. 

The eastern side of the canyon provides the best record of the Macrolobatus Zone, which is represented by several beds yielding ammonoids of the Tropites group, together with Anatropites div. sp. 

Conodont faunas from both these and higher beds are dominated by ornate metapolygnthids that would formerly have been collectively referred to Metapolygnathus primitius, a species long known to straddle the CNB. Within this lower part of the section, they resemble forms that have been separated as Metapolygnathus mersinensis. Slightly higher, forms close to Epigondolella' orchardi and a single Orchardella n. sp. occur. This association can be correlated with the latest Carnian in British Columbia.

Higher in the section, the ammonoid fauna shows a sudden change and is dominated by Tropithisbites. Few tens of metres above, but slightly below the first occurrence of Norian ammonoids Guembelites jandianus and Stikinoceras, two new species of conodonts (Gen et sp. nov. A and B) appear that also occur close to the favoured Carnian/Norian boundary at Black Bear Ridge, British Columbia. Stratigraphically higher collections continue to be dominated by forms close to M. mersinensis and E. orchardi after BC's own Mike Orchard.

The best exposure of the Kerri Zone is on the western side of the West Union Canyon. Ammonoids, dominated by Guembelites and Stikinoceras div. sp., have been collected from several fossil-bearing levels. Conodont faunas replicate those of the east section. The collected ammonoids fit perfectly well with the faunas described by Silberling in 1959, but they differ somewhat from coeval faunas of the Tethys and Canada. 

The ammonoid fauna paints a compelling picture of Tethyan influence with a series of smoking guns. We see an abundance of Tropitidae in the Carnian, a lack of Pterosirenites in the Norian, copious Guembelites, the Tethyan species G. philostrati, the stratigraphic position of G. clavatus and the rare occurrence of Gonionotites. Their hallelujah moment was likely finding an undescribed species of the thin-shelled bivalve Halobia similar to Halobia beyrichi — the clincher that perhaps seals this deal on Tethyan influence. 

I'll take a boo to see what Christopher McRoberts published on the find. A jolly good idea to have him on this expedition as it would have been easy to overlook if the focus remained solely on the conodonts and ammonoids. McRoberts has published on the much-studied Pardonet Formation up in the Willison Lake Area of Northeastern, British Columbia. He knows a thing or two about Upper Triassic Bivalvia and the correlation to coeval faunas elsewhere in the North American Cordillera, and to the Boreal, Panthalassan and Tethyan faunal realms. 

If you fancy a read, they published a paper: "Towards the definition of the Carnian/Norian Boundary: New data on Ammonoids and Conodonts from central Nevada," which you can find in the proceedings of the 21st Canadian Paleontology Conference; by Haggart, J W (ed.); Smith, P L (ed.); Canadian Paleontology Conference Proceedings no. 9, 2011 p. 9-10.

Fig. 1. Location map of Berlin-Ichthyosaur State Park

Marco Balini, James Jenks, Riccardo Martin, Christopher McRoberts, along with Mike Orchard and Norman Siberling, did a bed by bed sampling in 2013 and published on The Carnian/Norian boundary succession at Berlin-Ichthyosaur State Park (Upper Triassic, central Nevada, USA) and published in January 2014 in Paläontologische Zeitschrift 89:399–433. That work is available for download from ResearchGate. The original is in German, but there is a translation available.

After years of reading about the correlation between British Columbia and Nevada, I had the very great pleasure of walking through these same sections in October 2019 with members of the Vancouver Paleontological Society and Vancouver Island Palaeontological Society. It was with that same crew that I'd originally explored fossil sites in the Canadian Rockies in the early 2000s. Those early trips led to paper after paper and the exciting revelations that inspired our Nevada adventure.

If you plan your own adventure, you'll want to keep an eye out for some of the other modern fauna — mountain lions, snakes, lizards, scorpions, wolves, coyotes, foxes, ground squirrels, rabbits, falcons, hawks, eagles, bobcats, sheep, deer and pronghorns.

LYSAKER MEMBER TRILOBITE

Niobe schmidti (Balashova, 1976)

This gorgeous trilobite is an exceptionally well-preserved Niobe schmidti (Balashova, 1976) from middle Ordovician limestone deposits of the Huk Formation, Lysaker member near Oslo, Norway. 

The limestones of the Huk Formation have an extreme geological history and fossils from this formation are usually very difficult to prepare. 

The beige/grey limestones are often heavily cemented to the shelly material, which can be quite fragile.

The rich chocolate coloured specimen you see here was no exception. It presented many challenges in its 26 hours of preparation but each of these was overcome by the patience and skill of Paul Freitag Wolvers at Freitag Fossils. 

I have added a link below with a series of photos so you can walk through the preparation process step by step with Paul. If you have a special specimen you would like prepped, I highly recommend you contact him. His work is outstanding.

Superb prep of this Niobe schmidti (Balashova, 1976)

The shell was partly hollow, very fragile and stuck firmly to the matrix. The positive was assembled from two pieces and much of the shell of the left half of the trilobite had to be transferred over from the negative — no small feat. 

Despite these challenges, the final result is superb. This Niobe schmidti is a museum-quality specimen with exquisite preservation. You can clearly see the lovely terrace lines, pores and eye lenses are excellent to study.  

This specimen hails from the middle Ordovician. The Ordovician lasted almost 45 million years, beginning 488.3 million years ago and ending 443.7 million years ago. 

It was the time in our Earth's history when the area north of the tropics was almost entirely underwater and most of the world's land was collected into the southern supercontinent of Gondwana. Throughout the Ordovician, Gondwana slowly shifted towards the South Pole and much of it remained submerged under an ancient ocean.

Niobe schmidti (Balashova, 1976)

At the time that this fellow was making a living in our ancient seas, he would have been joined by a diverse community of marine invertebrates —graptolites, fellow trilobites, brachiopods and the early vertebrate conodonts. 

These marine communities were joined by red and green algae, primitive fish, cephalopods, corals, crinoids, and gastropods. 

We also find stunning tetrahedral spores similar to those of primitive land plants which tell us who was living on the land at the time.

One of the first specimens of this lovely species I had the pleasure to see was from the Voybokalo Quarry near St. Petersburg in Russia. These outcrops are part of the Kunda Horizon, Lower Ordovician, Asaphus expansus zone and run roughly 468 million years old. 

From the Lower to Middle Ordovician, the Earth was enjoying a mild, humid climate — the weather was warm and the atmosphere contained a significant amount of moisture. 

Once Gondwana finally settled on the South Pole during the Upper Ordovician, massive glaciers formed. These drained the shallow seas and ocean levels dropped. By the end of the Ordovician, 60% of all marine invertebrates and 25% of all life on Earth disappeared as part of the Ordovician mass extinction event. We enjoy many of those species now only as fossils and if we are lucky, preserved in remarkable detail.

KHATSAHLANO: A FOREST FIRE IN STONE

In the Field with Vancouverite Geoscientist Andy Randell — We were super excited to spend a day with the awesome possum that is Andy Randell filming fossils in the field.

We braved the wet and cold on this fine day to head out in search of fossil plants along the Kitsilano foreshore.

And find them we did! 40 million-year-old pretty as you please plant fossils

The Kitsilano fossil plant sites are intriguing as they hold a mystery... why ONLY plants and NO animal fossils? Nary an insect, mammal or reptile to be found. 

We did find some truly lovely plant fossils that speak to a warmer, wetter environment than the Kitsilano we know today. 

Andy shared that the sediments that lay on the foreshore along Kitsilano Beach are thought to be from the Upper Eocene / Early Oligocene in age (38 to 28 million years old), although opinion varies on the exact age with some folk thinking they may be as much as 40 million-years-old. 

The rocks here are layered in stacks of sand, silt and mudstones associated with a lowland estuarine or deltaic environment. If you look closely, you can see signs of the water meandering into channels and ponds of still water. 

The area would have formed a basin, surrounded by mountains that were drained by rivers into this area. It seems that there are no indications of any marine incursions in the sediment pile, and so the area is assumed to have remained stable for some time.

Plant fossils are common in these beds and are often well preserved. The most common are broadleaved deciduous species such as beech, oak, chestnut and hazel, although several coniferous species are known including redwoods (Sequoia), larch, pine and spruce. The deciduous trees like low, moist landscapes which fit with the basin model. The coniferous species likely lived on the surrounding hills where the ground was somewhat drier and their remains transported by rivers into the depositional basin.

There are also regular signs of burning in the fossils – indicating some kind of forest fire events that must have occurred with some frequency.

You will want to catch his wonderfully engaging interviews. Andy is a professional geologist living in Vancouver who is tailoring his career to bring change to the minerals exploration industry. 

Since 2014, he has established his consulting business, SGDS Hive, which takes on graduate geoscientists and mentors them through a variety of exploration projects to help engage and educate the next generation of geologists. 

Andy is the engine behind Below BC, a non-profit society that provides outreach to the public around Earth Science topics, which now serves several thousand people in British Columbia each year. 

His love of geology and palaeontology started early. Andy is a wealth of knowledge on fossil plants. Growing up on the Isle of Wight, he studied plants that are remarkably similar to those we looked at today—and he is a natural behind the lens!

We were joined by my good friend Lauren, the deeply awesome John Fam, Vice-Chair of the Vancouver Paleontological Society & his two boys, Oliver & Liam. 

It was Liam's first fossil field trip & my 7-month old Flat Coat Retriever's first foray into the field. Both Liam and Coco had a grand time! He found fossils that she inspected and on occasion took a wee bite of to see what all the fuss was about.

We were blessed to have David, Andy's partner, teacher & botany buff, along with their two palaeo puppers — Daisy & Dobby — to complete our escort.

With Andy's guidance, everyone found fossil material and learned a lot about how these fossils were originally laid down in a river system.

A huge thank you to Gabriel Mesquita our talented cinematographer! It was a cold, wet day and the entire crew were troopers. If you are planning to visit the Kitsilano foreshore to look for fossils, know that the stairwell access at the base of Dunbar/Alma Street has been washed away. 

You'll want to head to Waterloo Street and make your way to the beach on the rather steep stairwell found there. Surface collecting is fine at this site. Wear rubber boots and know that the rock is very slippery.

ABALONE: GWA'LIT'SA

Abalone is the common name for a group of large marine snails — gastropod molluscs in the genus Haliotis, family Haliotidae.

Haliotis once contained six subgenera but these are now grouped together as alternate representations of Haliotis. 

In the Pacific Northwest, our rocky shores are home to the Northern or Pinto abalone, Haliotis kamtschatkana. 

In the Kwak̓wala language of the Kwakiutl or Kwakwaka'wakw, speakers of Kwak'wala, of the Pacific Northwest, abalone are known as gwa'lit̕sa.

They range from Mexico to Alaska and are the only abalone species found in Washington state, British Columbia and Alaska. Abalone prefer to live amongst the cold waters and high surf of rocky reef habitats. They are easily harvested as their sweet spot is water between 3-18 meters or 10-60 feet deep.  

The shells of abalones have a low, open spiral structure, and are characterized by several open respiratory pores in a row near the shell's outer edge. The thick inner layer of the shell is composed of nacre or mother-of-pearl. Their iridescent nacre is gorgeous and runs from white to blue to green. Both their meat and their shells are highly prized. 

The Northern or Pinto abalone is protected today. Those looking to use the shell for decorative purposes must now look to California or New Zealand. The California abalone is more colourful than its northern cousin and has long been preferred by First Nations artists, particularly for the large earrings favoured by women of rank amongst First Nations of the Pacific Northwest. 

My relatives are no exception. This wonderful photo of Dzawada'enuxw Margaret Frank neé Wilson wearing abalone shell earrings was taken by Edward Curtis on his visit to the northern end of Vancouver Island in 1914. 

Curtis visited many of my relatives and took numerous photos for which we are eternally grateful as they capture a time in history where the use of photography was limited. 

When he filmed In the Land of the Head Hunters, Dzawada'enuxw Margaret Frank was featured. It was later named, much more appropriately, In the Land of the War Canoes.

He also captured the work of Anisalaga, Mary Ebbetts Hunt, on these visits. When she married Robert Hunt, her son William, my great great grandfather married Annie Wilson. 

It is through Annie that I am related to this beautiful soul captured here.

OH, WHAT WE DO FOR FOSSILS

Coroniceras sp. from Sayward, British Columbia

This yummy Lower Jurassic ammonite with the creamy dark chocolate colouring is from an all but inaccessible outcrop of the Upper Sinemurian, Bonanza Group,  Harbledownense Zone, Memekay River area, near Sayward, Vancouver Island, British Columbia, Canada. 

This area is home to the We Wai Kai and Wei Wai Kum First Nations and lands of the K'omoks whose culture thrives and reflects the natural rugged beauty of the central island region.

I passed through Sayward earlier this month on the way to northern Vancouver Island. 

It is rugged, remote and beautiful. Think trees and valleys for as far as the eye can see. Some of those hillsides on the horizon contain wonderful fossils, including this Coroniceras sp. with the truly marvellous keel.

By the time these ammonites were being buried in sediment, Wrangellia, the predominately volcanic terrane that now forms Vancouver Island and Haida Gwaii, had made its way to the northern mid-latitudes.

Within the basal part of the sequence, sedimentary beds are found interbedded with lapilli and crystal tuffs. Here you'll see maroon tuffaceous sandstone, orange-grey sandstone, granule sandstone and conglomerate. Within them we find ammonites nestled in with gastropods and pelecypods. 

While the fossiliferous outcrop is quite small, the Bonanza group is much larger, estimated to be at least 1000 metres thick. The site is quite small and in an active logging area, so the window to collect was limited. The drive up the mountain was thrilling as there had just been heavy rains and the road was washed out and narrowed until it was barely the width of our wheelbase and very, very steep. Closer to the top it narrowed to be just shy of the width of the vehicle — thrilling, to say the least. 

So scary that my passengers all got out as there was a high probability of going head-first over the edge. I was navigating by some handwritten field notes and a wee map on a paper napkin that should have read, "park at the bottom and hike up." 

Did we park at the bottom and hike up? No, we did not. 

The torrential rains of the Pacific Northwest had been working their magic on the hillside and slowly washing out the road until it slowly became more of a trail.

At the base of the hillside all looked well. Giddy for the fossils to come, we ventured off with a truck full of enthusiasm. Within 15 minutes of steep elevation gain, we had a wonderful view of the valley below. We were halfway up the mountain before I realized the error of my ways. The road twisted and turned then slowly narrowed to the width of my tires. Too narrow to turn around, so the only way was up. 

Graham Beard from Qualicum Beach was the fellow who showed me the site and drew the wee map for me. I cannot recall everyone on the trip, but Perry Poon was there — he shot a video of the drive up that he described as thrilling. I have never seen it but would like to one day — and so was Patricia Coutts with her lovely Doberman. 

She and I had just done a trip up to Goldbridge where the cliff we were on had turned into a landslide into a ravine so she was feeling understandably cautious about the power of Mother Nature. 

Picture the angle, the hood of my jeep riding high and hiding what remained of the road beneath and a lovely stick shift that made you roll backwards a wee bit with every move to put it into gear. So, without being able to see the very narrow path beneath, I had to just keep going. 

Both Perry and Patricia helped with filling in the potholes so my tires would have something to grip. 

I bent the frame on the jeep heading up and had some explaining to do when I returned it to the car rental place. 

As I recall, I wasn't in my ordinary vehicle but a rental because my car had been stolen the weekend before when I was away with John Fam and Dan Bowen collecting at Jurassic Point, an epic fossil site accessible only by boat on our wild west coast.

Fortuitous timing really, as they stole my car but I had unloaded my precious fossil collecting gear out of the trunk just days before.  

In the end, we found what we were looking for. Memekay yields a mix of ammonites, gastropods and bivalves. 

Many of them are poorly preserved. It was a hell of a ride but well worth the effort as we found some great fossils and with them more information on the palaeontology and geology of Vancouver Island. Just look at the keel on this beauty.

I would share the site information but it is now covered over with debris and inaccessible. One day, this whole region will be developed and the site will be opened up again. Until then, we'll have to enjoy what has been unearthed.

FIRST DINOSAUR FROM VANCOUVER ISLAND

This dapper fellow is a pine needle and horsetail connoisseur. He's a hadrosaurus — a duck-billed dinosaur. They were a very successful group of plant-eaters that thrived throughout western Canada during the late Cretaceous, some 70 to 84 million years ago.

Hadrosaurs lived as part of a herd, dining on pine needles, horsetails, twigs and flowering plants.

Hadrosaurs are ornithischians — an extinct clade of mainly herbivorous dinosaurs characterized by a pelvic structure superficially similar to that of birds. They are close relatives and possibly descendants of the earlier iguanodontid dinosaurs. 

They had slightly webbed, camel-like feet with pads on the bottom for cushioning and perhaps a bit of extra propulsion in water. They were primarily terrestrial but did enjoy feeding on plants near and in shallow water. There had a sturdy build with a stiff tail and robust bone structure. 

At their emergence in the fossil record, they were quite small, roughly three meters long. That's slightly smaller than an American bison. They evolved during the Cretaceous with some of their lineage reaching up to 20 meters or 65 feet.

Hadrosaurs are very rare in British Columbia but a common fossil in our provincial neighbour, Alberta, to the east. Here, along with the rest of the world, they were more abundant than sauropods and a relatively common fossil find. They were common in the Upper Cretaceous of Europe, Asia, and North America.

There are two main groups of Hadrosaurs, crested and non-crested. The bony crest on the top of the head of the hadrosaurs was hollow and attached to the nasal passages. It is thought that the hollow crest was used to make different sounds. These sounds may have signalled distress or been the hadrosaur equivalent of a wolf whistle used to attract mates. Given their size it would have made for quite the trumpeting sound.

This beautiful specimen graces the back galleries of the Courtenay and District Museum on Vancouver Island, British Columbia, Canada. I was very fortunate to have a tour this past summer with the deeply awesome Mike Trask joined by the lovely Lori Vesper. The museum houses an extensive collection of palaeontological and archaeological material found on Vancouver Island, many of which have been donated by the Vancouver Island Palaeontological Society.

Dan Bowen, Chair of the Vancouver Island Palaeontological Society, shared the photo you see here of the first partly articulated dinosaur from Vancouver Island ever found. The vertebrate photo and illustration are from a presentation by Dr. David Evans at the 2018 Paleontological Symposium in Courtenay.  The research efforts of the VIPS run deep in British Columbia and this new very significant find is no exception. A Hadrosauroid dinosaur is a rare occurrence and further evidence of the terrestrial influence in the Upper Cretaceous, Nanaimo Group, Vancouver Island — outcrops that we traditionally thought of as marine from years of collecting well-preserved marine fossil fauna.

CDM 002 / Hadrosauroid Caudal Vertebrae

The fossil bone material was found years ago by Mike Trask of the Vancouver Island Palaeontological Society. You may recall that he was the same fellow who found the Courtenay Elasmosaur on the Puntledge River.

Mike was leading a fossil expedition on the Trent River. While searching through the Upper Cretaceous shales, the group found an articulated mass of bones that looked quite promising.

Given the history of the finds in the area, the bones were thought to be from a marine reptile.

Since that time, we've found a wonderful terrestrial helochelydrid turtle, Naomichelys speciosa, but up to this point, the Trent had been known for its fossil marine fauna, not terrestrial. Efforts were made to excavate more of the specimen, and in all more than 25 associated vertebrae were collected with the help of some 40+ volunteers. Identifying fossil bone is a tricky business. Encased in rock, the caudal vertebrae were thought to be marine reptile in origin. Some of these were put on display in the Courtenay Museum and mislabeled for years as an unidentified plesiosaur.

In 2016, after years of collecting dust and praise in equal measure, the bones were reexamined. They didn't quite match what we'd expect from a marine reptile. Shino Sugimoto, Fossil Preparator, Vertebrate Palaeontology Technician at the Royal Ontario Museum was called in to work her magic — painstakingly prepping out each caudal vertebrae from the block.

Once fully prepped, seemingly unlikely, they turned out to be from a terrestrial hadrosauroid. This is the second confirmed dinosaur from the Upper Cretaceous Nanaimo Group. The first being a theropod from Sucia Island consisting of a partial left thigh bone — the first dinosaur fossil ever found in Washington state.

Dr. David Evans, Temerty Chair in Vertebrate Palaeontology, Department of Natural History, Palaeobiology from the Royal Ontario Museum, confirmed the ID and began working on the partial duck-billed dinosaur skeleton to publish on the find.

Drawing of Trent River Hadrosauroid Caudal Vertebrae

Now fully prepped, the details of this articulated Hadrosauriod caudal vertebrae come to light. We can see the prominent chevron facets indicative of caudal vertebrae with a nice hexagonal centrum shape on its anterior view.

There are well-defined long, raked neural spines that expand distally — up and away from the acoelous centrum. 

Between the successive vertebrae, there would likely have been a fibrocartilaginous intervertebral body with a gel-like core —  the nucleus pulposus — which is derived from the embryonic notochord. This is a handy feature in a vertebrate built as sturdily as a hadrosaur. Acoelous vertebrae have evolved to be especially well-suited to receive and distribute compressive forces within the vertebral column.

This fellow has kissing cousins over in the state of New Jersey where this species is the official state fossil. The first of his kind was found by John Estaugh Hopkins in New Jersey back in 1838. Since that time, we've found many hadrosaurs in Alberta, particularly the Edmontosuaurs, another member of the subfamily Hadrosaurine.

In 1978, Princeton University found fifteen juvenile hadrosaurs, Maiasaura ("good mother lizard") on a paleontological expedition to the Upper Cretaceous, Two Medicine Formation of Teton County in western Montana. 

Their initial finds of several small skeletons had them on the hunt for potential nests — and they found them complete with wee baby hatchlings!

VIPS LECTURE: DAVE EVANS, HADROSAURS AND ORNITHOMIMIDS

Dr. David Evans, Hadrosaurs & Ornithomimids

Join us for a VIPS Zoom Lecture with Dr. David Evans to learn about dinosaur discoveries on Vancouver Island.  

A Hadrosauroid dinosaur is a rare occurrence and further evidence of the terrestrial influence in the Upper Cretaceous, Nanaimo Group, Vancouver Island — outcrops that we traditionally thought of as marine from years of collecting well-preserved marine fossil fauna.

The fossil bone material was found years ago by Mike Trask of the Vancouver Island Palaeontological Society. You may recall that he was the same fellow who found the Courtenay Elasmosaur on the Puntledge River.

Mike was leading a fossil expedition on the Trent River. While searching through the Upper Cretaceous shales, the group found an articulated mass of bones that looked quite promising.

Given the history of the finds in the area, the bones were thought to be from a marine reptile.

In 2016, after years of collecting dust and praise in equal measure, the bones were reexamined. They didn't quite match what we'd expect from a marine reptile. Shino Sugimoto, Fossil Preparator, Vertebrate Palaeontology Technician at the Royal Ontario Museum was called in to work her magic — painstakingly prepping out each caudal vertebrae from the block.

Once fully prepped, seemingly unlikely, they turned out to be from a terrestrial hadrosauroid. This is the second confirmed dinosaur from the Upper Cretaceous Nanaimo Group. The first being a theropod from Sucia Island consisting of a partial left thigh bone — the first dinosaur fossil ever found in Washington state.

FISHAPODS OF ELLESMERE ISLAND

Qikiqtania wakei, a fishapod & relative to tetrapods

You will likely recall the amazing tetrapodomorpha fossil found on Ellesmere Island in the Canadian Arctic in 2004, Tiktaalik roseae. 

These were advanced forms transitional between fish and the early labyrinthodonts playfully referred to as fishapods — half-fish, half-tetrapod in appearance and limb morphology. 

Up to that point, the relationship of limbed vertebrates (tetrapods) to lobe-finned fish (sarcopterygians) was well known, but the origin of significant tetrapod features remained obscure for the lack of fossils that document the sequence of evolutionary changes — until Tiktaalik. 

While Tiktaalik is technically a fish, this fellow is as far from fish-like as you can be and still be a card-carrying member of the group. 

Interestingly, while Neil Shubin and crew were combing the icy tundra for Tiktaalik, another group was trying their luck just a few kilometres away. 

A week before the eureka moment of Tiktaalik's discovery, Tom Stewart and Justin Lemberg unearthed material that we now know to be a relative of Tiktaalik's. 

Meet Qikiqtania wakei, a fishapod and close relative to our dear tetrapods — and cousin to Tiktaalik — who shares features in the flattened triangular skull, shoulders and elbows in the fin. 

Qikiqtania (pronounced kick-kick-TAN-ee-ya)

But, and here’s the amazing part, its upper arm bone (humerus) is specialised for open water swimming, not walking. 

The story gets wilder when we look at Qikiqtania’s position on the evolutionary tree— all the features for this type of swimming are newly evolved, not primitive. 

This means that Qikiqtania secondarily reentered open water habitats from ancestors that had already had some aspect of walking behaviour. 

And, this whole story was playing out 365 million years ago — the transition from water to land was going both ways in the Devonian.

Why is this exciting? You and I descend from those early tetrapods. We share the legacy of their water-to-land transition and the wee bony bits in their wrists and paddles that evolved to become our hands. I know, mindblowing!

Thomas Stewart and Justin Lemberg put in thousands of hours bringing Qikiqtania to life. 

The analysis consisted of a long path of wild events— from a haphazard moment when it was first spotted, a random collection of a block that ended up containing an articulated fin, to a serendipitous discovery three days before Covid lockdowns in March 2020.

Both teams acknowledge the profound debt owed to the individuals, organizations and indigenous communities where they had the privilege to work — Grise Fiord and Resolute Bay— Ellesmere Island in Nunavut, the largest and northernmost territory of Canada. 

Part of that debt is honoured in the name chosen for this new miraculous species. 

Aerial View of Ellesmere Island

The generic name, Qikiqtania (pronounced kick-kick-TAN-ee-ya), is derived from the Inuktitut words Qikiqtaaluk and Qikiqtani which are the traditional place name of the region where the fossil was discovered. 

The specific name, wakei, is in memory of the evolutionary biologist David Wake — colleague, mentor and friend. 

He was a professor of integrative biology and Director and curator of herpetology at the Museum of Vertebrate Zoology at the University of California, Berkeley who passed away in April 2021. 

Wake is known for his work on the biology and evolution of salamanders and vertebrate evolutionary biology. 

If you look at the photo on the left you can imagine visiting these fossil localities in Canada's far north.

Qikiqtania was found on Inuit land and belongs to the community. Thomas Stewart and his colleagues were able to conduct this research because of the generosity and support of individuals in the hamlets of Resolute Bay and Grise Fiord, the Iviq Hunters and Trappers of Grise Fiord, and the Department of Heritage and Culture, Nunavut.

To them, on behalf of the larger scientific community — Nakurmiik. Thank you!

STORYHIVE VOICES: MEET JULIUS CSOTONYI

Julius Csotonyi BTS on BC'S FOSSIL BOUNTY

Meet Julius Csotonyi — scientist, natural history illustrator, conservationist and biological sciences graduate with a passion for drawing dinosaurs. 

He got hooked on the palaeontology bug early and has been doodling dinosaurs since childhood. 

Over the years, he has expanded his portfolio to include all branches of scientifically inspired artwork — each of them beautifully rendered. 

He has collaborated on projects with several major museums and book publishers from around the globe, including the National Geographic Society and the Royal Tyrrell Museum, working closely with scientists and drawing from his scientific background. 

An MSc graduate of Ecology and Environmental Biology (University of Alberta), and a PhD graduate in microbiology (University of Manitoba), he has published scientific papers on mutualisms in Utah and some very cool and unusual alien-looking bacteria from deep ocean hydrothermal volcanic vents. 

His scientific background fuels his passion to strive to restore as realistically as possible the curiously alien environments that earth has hosted in its deep past. 

His style spans the gamut from pencil and ink line drawings to watercolour, pastel, 2-dimensional digital illustrations and 3-dimensional digital models. His superbly detailed work encompasses dinosaurs and other prehistoric life, sharks and other living animals, as well as space art, fantasy and science fiction themes.

Julius Csotonyi's Hell Creek Raptor

His paleoart career began with work on two dinosaur encyclopedias with UK author Dougal Dixon. 

His largest projects to date have been a panoramic 75-foot-long mural commissioned for the Houston Museum of Natural Science (HMNS), depicting a Late Cretaceous Montana ecosystem along with a mummified Brachylophosaurus —  Dinosaur Mummy CSI: Cretaceous Science Investigation, 2008. 

He has illustrated many life-sized dinosaur murals — some up to 45 metres or 150 feet long — for the Royal Ontario Museum's 2012 exhibit, Ultimate Dinosaurs; Giants from Gondwana. 

Julius illustrated the 25th anniversary exhibit ('Alberta Unearthed') for the Royal Tyrrell Museum of Paleontology (Drumheller, Alberta, 2010) and most of the new Hall of Paleontology at the HMNS. 

Some of his other projects have included the ceratopsian exhibit for the Royal Tyrrell Museum (2007), a mummified Edmontosaurus for Phillip Manning's 'Grave Secrets of Dinosaurs' (National Geographic Books, 2007) and an African Massospondylus nesting site (Royal Ontario Museum, Toronto, 2010). In addition to books and museum projects, 

Csotonyi accepts private commissions of artwork in a wide range of digital and traditional media. His website, http://csotonyi.com, features a growing portfolio of his work, and some of it is also featured on his science blog, 'Evolutionary Routes'. 

He is appearing in BC'S FOSSIL BOUNTY — airing on TELUS Optik TV & the TELUS YouTube Channel beginning Autumn 2022.

KU'MIS: WARRIOR CRAB

Look how epic this little guy is! 

He is a crab — and if you asked him, the fiercest warrior that ever lived. While that may not be strictly true, crabs do have the heart of a warrior and will raise their claws, sometimes only millimetres into the air, to assert dominance over their world. 

Crabs are decapod crustaceans of the Phylum Arthropoda. 

In the Kwak'wala language of the Kwakwa̱ka̱ʼwakw First Nations of the Pacific Northwest, this brave fellow is ḵ̓u'mis — both a tasty snack and familiar to the supernatural deity Tuxw'id, a female warrior spirit. Given their natural armour and clear bravery, it is a fitting role.

They inhabit all the world's oceans, sandy beaches, many of our freshwater lakes and streams. Some few prefer to live in forests.

Crabs build their shells from highly mineralized chitin — and chitin gets around. It is the main structural component of the exoskeletons of many of our crustacean and insect friends. Shrimp, crab, and lobster all use it to build their exoskeletons.

Chitin is a polysaccharide — a large molecule made of many smaller monosaccharides or simple sugars, like glucose. 

It is handy stuff, forming crystalline nanofibrils or whiskers. Chitin is actually the second most abundant polysaccharide after cellulose. It is interesting as we usually think of these molecules in the context of their sugary context but they build many other very useful things in nature — not the least of these are the hard shells or exoskeletons of our crustacean friends.

Crabs in the Fossil Record

The earliest unambiguous crab fossils date from the Early Jurassic, with the oldest being Eocarcinus from the early Pliensbachian of Britain, which likely represents a stem-group lineage, as it lacks several key morphological features that define modern crabs. 

Most Jurassic crabs are only known from dorsal — or top half of the body — carapaces, making it difficult to determine their relationships. Crabs radiated in the Late Jurassic, corresponding with an increase in reef habitats, though they would decline at the end of the Jurassic as the result of the decline of reef ecosystems. Crabs increased in diversity through the Cretaceous and represented the dominant group of decapods by the end.

We find wonderful fossil crab specimens on Vancouver Island. The first I ever collected was at Shelter Point, then again on Hornby Island, down on the Olympic Peninsula and along Vancouver Island's west coast near Nootka Sound. They are, of course, found globally and are one of the most pleasing fossils to find and aggravating to prep of all the specimens you will ever have in your collection. Bless them.

CHINESE REPTILIAN WING: SINOSAUROPTERYX

Sinosauropteryx prima

This glorious specimen is Sinosauropteryx, a small theropod caught in a traditional death pose. 

Only one species of Sinosauropteryx has been named: S. prima, meaning "first" in reference to its status as the first feathered non-avialian dinosaur species discovered. Three specimens have been described. The third specimen previously assigned to this genus represents either a second, as-yet unnamed species or a distinct, related genus.

Sinosauropteryx lived in what is now northeastern China during the early Cretaceous period. It was among the first dinosaurs discovered from the Yixian Formation in Liaoning Province, and was a member of the Jehol Biota. Well-preserved fossils of this species illustrate many aspects of its biology, such as its diet and reproduction.

They had unusually long tail and very short arms. The longest known specimen reaches up to 1.07 metres (3.51 feet) in length, with an estimated weight of 0.55 kilograms (1.21 pounds) It was a close relative of the similar but older genus Compsognathus, both genera belonging to the family Compsognathidae. 

Described in 1996, it was the first dinosaur taxon outside of Avialae (birds and their immediate relatives) to be found with evidence of feathers. Quite amazingly, we know what this lovely may have looked like in life, right down to its colouring! It was covered with a coat of very simple filament-like feathers with the wee structures that tell us what colour those feathers were. Sinosauropteryx is the first non-avialian dinosaur where we are able to do this. 

And what colour were they? They had a lovely reddish hue with a lighter banded tail. Some contention has arisen with an alternative interpretation of the filamentous impression as remains of collagen fibres, but this has not been widely accepted.

Sinosauropteryx (meaning "Chinese reptilian wing", simplified Chinese: 中华龙鸟; traditional Chinese: 中華龍鳥; pinyin: Zhōnghuá lóng niǎo; lit. 'Chinese dragon bird') is a compsognathid dinosaur. 

SABRE-TOOTHED SALMON OF WASHINGTON STATE

This toothy specimen is an Oncorhynchus nerka, a Pleistocene Sockeye Salmon from outcrops along the South Fork Skokomish River, Olympic Peninsula, Washington State, USA.

The area is home to the Skokomish — one of nine tribes of the Twana, Coast Salish First Nations in the northern-mid Puget Sound area of western Washington state in the United States. 

Each of the Tribal Nations are known by their locations — Dabop, Quilcene or salt-water people, Dosewallips, Duckabush, Hoodsport, Skokomish or Skoko'bsh, Vance Creek, Tahuya, and Duhlelap or Tule'lalap. The name Skokomish means river people or people of the river in the language of the Twana, sqʷuqʷóbəš or sqWuqWu'b3sH.

Closer to my home farther north in the Pacific Northwest on northern Vancouver Island are the Kwakiutl or Kwakwaka'wakw, speakers of Kwak'wala. Here, sockeye salmon are known as ma̱łik. You would likely recognize these fossils' modern counterparts from their distinctive red bodies and greenish heads. 

Their descendants had been absent from the Skokomish River for more than a decade up to 2014 when construction to augment the negative impact of the Cushman Reservoir was undertaken to restore their natural habitat.

The fossil specimens include individuals with enlarged breeding teeth and worn caudal fins. It is likely that these salmon acted very similar to their modern counterparts with males partaking in competitive and sneaky tactics to gain access to the sexiest (large and red) females who were ready to mate. These ancient salmon had migrated, dug their nests, spawned and defended their eggs prior to their death. For now, we're referring to the species found here as Oncorhynchus nerka, as they have many of the characteristics of sockeye salmon, but also several minor traits of the Pink Salmon, Oncorhynchus gorbuscha.

I had expected to learn that the locality contained a single or just a few partial specimens, but the fossils beds are abundant with large, 45–70 cm, four-year-old adult salmon concentrated in a beautiful sequence of death assemblages.

Oncorhynchus nerka, Pleistocene Sockeye Salmon

Gerald Smith, a retired University of Michigan professor was shown the specimens and recognized them as Pleistocene, a time when the northern part of North America was undergoing a series of glacial advances and retreats that carved their distinctive signature into the Pacific Northwest.

It looks as though this population diverged from the original species about one million years ago, possibly when the salmon were deposited at the head of a proglacial lake impounded by the Salmon Springs advancement of a great glacier known as the Puget lobe of the Cordilleran Ice Sheet. 

Around 17,000 years ago, this 3,000 foot-thick hunk of glacial ice had made its way down from Canada, sculpting a path south and pushing its way between the Cascade and Olympic Mountains. The ice touched down as far south as Olympia, stilled for a few hundred years, then began to melt.

After the ice began melting and retreating north, the landscape slowly changed —  both the land and sea levels rising — and great freshwater lakes forming in the lowlands filled with glacial waters from the melting ice. The sea levels rose quite considerably, about one and a half centimetres per year between 18,000 and 13,000 years ago. The isostatic rebound (rising) of the land rose even higher with an elevation gain of about ten centimetres per year from 16,000 to 12,500 years ago.

Around 14,900 years ago, sea levels had risen to a point where the salty waters of Puget Sound began to slowly fill the lowlands. Both the land and sea continued to rise and by 5,000 years ago, the sea level was about just over 3 meters lower than it is today. The years following were an interesting time in the geologic history of the Pacific Northwest. The geology of the South Fork Skokomish River continued to shift, undergoing a complicated series of glacial damming and river diversions after these salmon remains were deposited.

Today, we find their remains near the head of a former glacial lake at an elevation of 115 metres on land owned by the Green Diamond Company. The first fossil specimens were found back in 2001 by locals fishing for trout along the South Fork Skokomish River.

Upon seeing the fossil specimens, Smith teamed up with David Montgomery of the University of Washington, Seattle, along with N. Phil Peterson and Bruce Crowley, a Late Oligocene Mysticete specialist from the Burke Museum, to complete fieldwork and author a paper.

The fossil specimen you see here is housed in the Burke Museum collection. They opened the doors to their new building and exhibitions in the Fall of 2019. These photos are by the deeply awesome John Fam from a trip to see the newly opened exhibits this year.

MCABEE FOSSIL BEDS

The McAbee Fossil Beds are known for their incredible abundance, diversity and quality of fossils including lovely plant, insect and fish species that lived in an old lake bed setting 52-53 million years ago.

It is one of the best local sites in the province to experience a fossil dig first-hand. It's an easy 4-hour drive from Vancouver and easily done as a rather longish day trip. I headed up this past summer with some wonderful enthusiastic crew to see how things were progressing with its development.

The site was designated a Provincial Heritage Site under British Columbia's Heritage Conservation Act in July of 2012. The site was reopened to public tours and viewing this summer with plans to build out a visitor's centre and educational programs in the future.

We were greeted on the day by two wonderful hosts from the Bonaparte Band, Gayle Pierro and Leroy Antoine. Both were very welcoming and informative, sharing the lay of the land, a bit of their history with the workings and offering us a guided tour. 

From the road, it is a short drive up to the first staging area that houses visitor parking and a public washroom. The first Site Information station is a short stroll away and includes a tent with a table and maps showing plans for the site. Here, Gayle walked us through the vision for McAbee and showed us a selection of some of the species found here. 

We were asked to stop back on the way down and fill out a survey that asked about our experience and provide feedback that will help shape what McAbee is to become. A short hike up the hill towards the hoodoos leads to another staging area. Here, Leroy was our host and guide. He shared a bit more about the geology of the area and showed us specimens found over the summer.

As McAbee is a Heritage Site, their only request was that we stay within the marked area and trails and keep ourselves safe. Here safe means hydrated, shaded from the sun and avoiding both the resident rattlesnakes and cacti. McAbee offers an excellent opportunity for education and outreach both for locals and the larger community. It was very enjoyable to see the reactions of those visiting the site as they took in the wonderful diversity of fossil species and learning about the local history from our hosts.

The Province is committed to providing access to the site to scientists and the lay public. The direction on what happens next at McAbee is being driven by the Heritage Branch in consultation with members of the Shuswap Nation and Bonaparte Band. Bonaparte's traditional territory is located within the Shuswap Nation and includes the site where the McAbee Fossil Beds are situated. 

Local members of the Bonaparte Band are Secwepemc. They would like to share the spiritual significance of the area from a Secwepemc First Nation perspective and see McAbee as an indigenous tourism destination. So it looks like it will be paleontology, archaeology with a cultural focus to add spice. In any case, fossil viewing, and hopefully supervised collecting will continue with oversight to ensure significant fossil finds make their way to science.

It would be good to see McAbee take a page out of the Courtney and District Museum's playbook. You'll recall that it was the Puntledge Elasmosaur that sparked the expansion of that museum and inspired a whole host of outreach and educational programs. The Courtenay Museum has been offering paid guided tours to the elasmosaur heritage site for over a dozen years. 

They are members of the British Columbia Paleontological Alliance (BCPA), a union of professional and amateur paleontological organizations working to advance the science of paleontology in the province by fostering public awareness, scientific collecting and education, and by promoting communication among all those interested in fossils. Within that context, the Courtenay Museum are bound both by the BCPA constitution and bylaws, and of course, the laws around fossil collecting in British Columbia.

One of the sister sites to McAbee, the Driftwood Canyon Provincial Park Fossil Beds, offers an honours system for their site. Visitors may handle and view fossils but are asked to not take them home. Both Driftwood Canyon and McAbee are part of an arc of Eocene lakebed sites that extend from Smithers in the north, down to the fossil site of Republic Washington, in the south. The grouping includes the fossil sites of Driftwood Canyon, Quilchena, Allenby, Tranquille, McAbee, Princeton and Republic. Each of these localities provides important clues to our ancient climate.

The fossils range in age from Early to Middle Eocene. McAbee had a more temperate climate, slightly cooler and wetter than other Eocene sites to the south at Princeton, British Columbia, Republic in north-central Washington, in the Swauk Formation near Skykomish and the Chuckanut Formation of northern Washington state. The McAbee fossil beds consist of 30 metres of fossiliferous shale in the Eocene Kamloops Group.

The fossils are preserved here as impressions and carbonaceous films. We see gymnosperm (16 species); a variety of conifers (14 species to my knowledge); two species of ginkgo, a large variety of angiosperm (67 species); a variety of insects and fish remains, the rare feather and a boatload of mashed deciduous material. Nuts and cupules are also found from the dicotyledonous Fagus and Ulmus and members of the Betulaceae, including Betula and Alnus.

We see many species that look very similar to those growing in the Pacific Northwest today. Specifically, cypress, dawn redwood, fir, spruce, pine, larch, hemlock, alder, birch, dogwood, beech, sassafras, cottonwood, maple, elm and grape. If we look at the pollen data, we see over a hundred highly probable species from the site. Though rare, McAbee has also produced spiders, birds (and lovely individual feathers) along with multiple specimens of the freshwater crayfish, Aenigmastacus crandalli.

For insects, we see dragonflies, damselflies, cockroaches, termites, earwigs, aphids, leafhoppers, spittlebugs, lacewings, a variety of beetles, gnats, ants, hornets, stick insects, water striders, weevils, wasps and March flies. The insects are particularly well-preserved. Missing are the tropical Sabal (palm), seen at Princeton and the impressive Ensete (banana) and Zamiaceae (cycad) found at Eocene sites in Republic and Chuckanut, Washington.

McAbee is located just east of Cache Creek, just north of and visible from Highway 1/97. 14.5 km to be exact and exactly the distance you need to drink one large coffee and then need a washroom. You'll be pleased to know they have installed one at the site. McAbee is a site for hiking boots, hand, head and eye protection. They have a few resident rattlesnakes and prickly cacti to keep you on your toes. Keep yourself safe and well-hydrated. There will be someone to greet you and let you know if it is open to collecting or if you'll have to satisfy yourself by enjoying their interpretive offerings.

As you drive up, you'll see telltale hoodoos on the ridge to let you know you've reached the right spot. If you have a GPS, pop in these coordinates and you're on your way. 50°47.831′N 121°8.469′W.

FOSSILS ON JUAN DE FUCA STRAIGHT

River Otter on the Foreshore, Juan de Fuca Strait

We all dream of finding new species, and new fossil species in particular. This happens more than you think. 

As impossible as it sounds, it has happened numerous times at many fossils sites in British Columbia including Sooke on Vancouver Island.

The upper Oligocene Sooke Formation outcrops at Muir Beach on southwestern Vancouver Island, British Columbia where it is flanked by the cool, clear waters of the Strait of Juan de Fuca.

While the site has been known since the 1890s, my first trip here was in the early 1990s as part of a Vancouver Paleontological Society (VanPS) fossil field trip. This easy, beach walk locality is a wonderful place to collect fossils and is especially good for families. If you are solar-powered, you will enjoy the sun playing off the surf from May through September. If you are built of hardier stuff, then the drizzle of Spring or Autumn is a lovely, un-people-y time to walk the beachfront.

As well as amazing west coast scenery, the beach site outcrop has a lovely soft matrix with well-preserved fossil molluscs, often with the shell material preserved (Clark and Arnold, 1923).

By the Oligocene ocean temperatures had cooled to near modern levels and the taxa preserved here as fossils bear a strong resemblance to those found living beneath the Strait of Juan de Fuca today. Gastropods, bivalves, echinoids, coral, chitin and limpets are common-ish — and on rare occasions, fossil marine mammals, cetacean and bird bones are discovered.

The diving bird you see here is Stemec suntokum, a Fossil Plopterid from Sooke, British Columbia, Canada.

Fossil Bird Bones 

Back in 2013, Steve Suntok and his family found fossilized bones from a 25-million-year-old wing-propelled flightless diving bird while out strolling the shoreline near Sooke. Not knowing what they had found but recognizing it as significant, the bones were brought to the Royal British Columbia Museum to identify.

The bones found their way into the hands of Gary Kaiser. Kaiser worked as a biologist for Environment Canada and the Nature Conservatory of Canada. After retirement, he turned his eye from our extant avian friends to their fossil lineage. The thing about passion is it never retires. Gary is now a research associate with the Royal British Columbia Museum, published author and continues his research on birds and their paleontological past.

Kaiser identified the well-preserved coracoid bones as the first example from Canada of a Plotopteridae, an extinct family that lived in the North Pacific from the late Eocene to the early Miocene. In honour of the First Nations who have lived in the area since time immemorial and Steve Suntok who found the fossil, Kaiser named the new genus and species Stemec suntokum.

Magellanic Penguin Chick, Spheniscus magellanicus

This is a very special find. Avian fossils from the Sooke Formation are rare. We are especially lucky that the bird bone was fossilized at all.  These are delicate bones and tasty. Scavengers often get to them well before they have a chance and the right conditions to fossilize.

Doubly lucky is that the find was of a coracoid, a bone from the shoulder that provides information on how this bird moved and dove through the water similar to a penguin. It's the wee bit that flexes as the bird moves his wing up and down.

Picture a penguin doing a little waddle and flapping their flipper-like wings getting ready to hop near and dive into the water. Now imagine them expertly porpoising —  gracefully jumping out of the sea and zigzagging through the ocean to avoid predators. It is likely that the Sooke find did some if not all of these activities.

When preservation conditions are kind and we are lucky enough to find the forelimbs of our plotopterid friends, their bones tell us that these water birds used wing-propelled propulsion to move through the water similar to penguins (Hasegawa et al., 1979; Olson and Hasegawa, 1979, 1996; Olson, 1980; Kimura et al., 1998; Mayr, 2005; Sakurai et al., 2008; Dyke et al., 2011).

Kaiser published on the find, along with Junya Watanabe, and Marji Johns. Their work: "A new member of the family Plotopteridae (Aves) from the late Oligocene of British Columbia, Canada," can be found in the November 2015 edition of Palaeontologia Electronica. If you fancy a read, I've included the link below.

The paper shares insights into what we have learned from the coracoid bone from the holotype Stemec suntokum specimen. It has an unusually narrow, conical shaft, much more gracile than the broad, flattened coracoids of other avian groups. This observation has led some to question if it is, in fact, a proto-cormorant of some kind. We'll need to find more of their fossilized lineage to make any additional comparisons.

Sooke, British Columbia and Juan de Fuca Strait

Today, fossils from these flightless birds have been found in outcrops in the United States and Japan (Olson and Hasegawa, 1996). They are bigger than the Sooke specimens, often growing up to two metres.

While we'll never know for sure, the wee fellow from the Sooke Formation was likely about 50-65 cm long and weighed in around 1.72-2.2 kg — so roughly the length of a duck and weight of a small Magellanic Penguin, Spheniscus magellanicus, chick. 

To give you a visual, I have included a photo of one of these cuties here showing off his full range of motion and calling common in so many young.

The first fossil described as a Plotopteridae was from a wee piece of the omal end of a coracoid from Oligocene outcrops of the Pyramid Hill Sand Member, Jewett Sand Formation of California (LACM 8927). Hildegarde Howard (1969) an American avian palaeontologist described it as Plotopterum joaquinensis. Hildegarde also did some fine work in the La Brea Tar Pits, particularly her work on the Rancho La Brea eagles.

In 1894, a portion of a pelagornithid tarsometatarsus, a lower leg bone from Cyphornis magnus (Cope, 1894) was found in Carmanah Group on southwestern Vancouver Island (Wetmore, 1928) and is now in the collections of the National Museum of Canada as P-189401/6323. This is the wee bone we find in the lower leg of birds and some dinosaurs. We also see this same bony feature in our Heterodontosauridae, a family of early and adorably tiny ornithischian dinosaurs — a lovely example of parallel evolution.

While rare, more bird bones have been found in the Sooke Formation over the past decade. In 2013, three avian bones were found in a single year. The first two were identified as possibly being from a cormorant and tentatively identified as Phalacrocoracidae tibiotarsi, the large bone between the femur and the tarsometatarsus in the leg of a bird.

They are now in the collections of the Royal BC Museum as (RBCM.EH2013.033.0001.001 and RBCM.EH2013.035.0001.001). These bones do have the look of our extant cormorant friends but the specimens themselves were not very well-preserved so a positive ID is tricky.

The third (and clearly not last) bone, is a well-preserved coracoid bone now in the collection at the RBCM as (RBCM.EH2014.032.0001.001).

The fossil bird find was the first significant find by the Suntok family but not their last. Just last year, they found part of a fish dental plate was studied by Russian researcher Evgeny Popov who named this new genus and species of prehistoric fish Canadodus suntoki, which translates to the "Tooth from Canada." Perhaps not quite as inspired as Kaiser, but a lovely homage to these Citizen Scientists.

Sooke Fossil Fauna

Along with these rare bird bones, the Paleogene sedimentary deposits of the Carmanah Group on southwestern Vancouver Island have a wonderful diversity of delicate fossil molluscs (Clark and Arnold, 1923). Walking along the beach, look for boulders with white shelly material in them. You'll want to collect from the large fossiliferous blocks and avoid the cliffs. The lines of fossils you see in those cliffs tell the story of deposition along a strandline. Collecting from them is both unsafe and poor form as it disturbs nearby neighbours and is discouraged.

We find nearshore and intertidal genera such as Mytilus (mussels) and barnacles, as well as more typically subtidal predatory globular moon snails (my personal favourite), surf clams (Spisula, Macoma), and thin, flattened Tellin clams.

The preservation here formed masses of shell coquinas that cemented together but are easily worked with a hammer and chisel. Remember your eye protection and I'd choose wellies or rubber boots over runners or hikers.

You may be especially lucky on your day out. Look for the larger fossil bones of marine mammals and whales that lived along the North American Pacific Coast in the Early Oligocene (Chattian).

Concretions and coquinas on the beach have yielded desmostylid, an extinct herbivorous marine mammal, Cornwallius sookensis (Cornwall, 1922) and 40 cm. skull of a cetacean Chonecetus sookensis (Russell, 1968), and a funnel whale, a primitive ancestor of our Baleen whales. 

A partial lower jaw and molar possibly from a large, bear-like beach-dwelling carnivore, Kolponomos, was also found here. A lovely skull from a specimen of Kolponomos clallamensis (Stirton, 1960) was found 60 km southwest across the Strait of Juan de Fuca in the early Miocene Clallam Formation and published by Lawrence Barnes and James Goedert. That specimen now calls the Natural History Museum of Los Angeles County home and is in their collections as #131148.

Directions to Muir Creek Fossil Site at Sooke: 

From the town of Sooke west of Victoria, follow Highway 14 for about 14 kilometres. Just past the spot where the highway crosses Muir Creek, you will see a gravel parking area on your left. Pull in and park here. 

From the barrier, walk out to the beach and turn right (west) and walk until you see the low yellow-brown sandstone cliffs about 400 metres ahead. 

Look at the grey sandstone boulders on the beach with bits of white flecks in them. The fossil material here will most often be a whitish cream colour. Check for low tide before heading out and choose rubber boots for this beach adventure.
