GULLS ON THE FORESHORE: T'SIK'WI

A gull cries in protest at not getting his share of a meal

Gulls, or colloquially seagulls, are seabirds of the family Laridae in the suborder Lari.

The Laridae are known from not-yet-published fossil evidence from the Early Oligocene — 30–33 million years ago.

Three gull-like species were described by Alphonse Milne-Edwards from the early Miocene of Saint-Gérand-le-Puy, France.

Another fossil gull from the Middle to Late Miocene of Cherry County, Nebraska, USA, has been placed in the prehistoric genus Gaviota.

These fossil gulls, along with undescribed Early Oligocene fossils are all tentatively assigned to the modern genus Larus. Among those of them that have been confirmed as gulls, Milne-Edwards' "Larus" elegans and "L." totanoides from the Late Oligocene/Early Miocene of southeast France have since been separated in Laricola.

Gulls are most closely related to the terns in the family Sternidae and only distantly related to auks, skimmers and distantly to waders.

A historical name for gulls is mews, which is cognate with the German möwe, Danish måge, Swedish mås, Dutch meeuw, Norwegian måke/måse and French mouette. We still see mews blended into the lexicon of some regional dialects.

In the Kwak̓wala language of the Kwakwaka'wakw, speakers of Kwak'wala, of the Pacific Northwest and my family, gulls are known as t̕sik̕wi. Most folk refer to gulls from any number of species as seagulls. This name is a local custom and does not exist in the scientific literature for their official naming. Even so, it is highly probable that it was the name you learned for them growing up.

If you have been to a coastal area nearly everywhere on the planet, you have likely encountered gulls. They are the elegantly plumed but rather noisy bunch on any beach. You will recognize them both by their size and colouring.

Gulls are typically medium to large birds, usually grey or white, often with black markings on the head or wings. They typically have harsh shrill cries and long, yellow, curved bills. Their webbed feet are perfect for navigating the uneven landscape of the foreshore when they take most of their meals.

Most gulls are ground-nesting carnivores that take live food or scavenge opportunistically, particularly the Larus species. Live food often includes crab, clams (which they pick up, fly high and drop to crack open), fish and small birds. Gulls have unhinging jaws which allow them to consume large prey which they do with gusto.

Their preference is to generally live along the bountiful coastal regions where they can find food with relative ease. Some prefer to live more inland and all rarely venture far out to sea, except for the kittiwakes.

The larger species take up to four years to attain full adult plumage, but two years is typical for small gulls. Large white-headed gulls are typically long-lived birds, with a maximum age of 49 years recorded for the herring gull.

Gulls nest in large, densely packed, noisy colonies. They lay two or three speckled eggs in nests composed of vegetation. The young are precocial, born with dark mottled down and mobile upon hatching. Gulls are resourceful, inquisitive, and intelligent, the larger species in particular, demonstrating complex methods of communication and a highly developed social structure. Many gull colonies display mobbing behaviour, attacking and harassing predators and other intruders.

Certain species have exhibited tool-use behaviour, such as the herring gull, using pieces of bread as bait with which to catch goldfish. Many species of gulls have learned to coexist successfully with humans and have thrived in human habitats. Others rely on kleptoparasitism to get their food. Gulls have been observed preying on live whales, landing on the whale as it surfaces to peck out pieces of flesh. They are keen, clever and always hungry.

VANCOUVER ISLAND'S HIDDEN GEMS: TRENT RIVER

Dan Bowen, Chair, VIPS, Trent River

The rocks that make up the Trent River on Vancouver Island were laid down south of the equator as small, tropical islands. They rode across the Pacific heading north and slightly east over the past 85 million years to where we find them today.

The Pacific Plate is an oceanic tectonic plate that lies beneath the Pacific Ocean. And it is massive. At 103 million km2 (40 million sq mi), it is the largest tectonic plate and continues to grow fed by volcanic eruptions that piggyback onto its trailing edge.

This relentless expansion pushes the Pacific Plate into the North American Plate. The pressure subducts it beneath our continent where it then melts back into the earth. Plate tectonics are slow but powerful forces.

The island chains that rode the plates across the Pacific smashed into our coastline and slowly built the province of British Columbia. And because each of those islands had a different origin, they create pockets of interesting and diverse geology.

It is these islands that make up the Insular Belt — a physio-geological region on the northwestern North American coast. It consists of three major island groups — and many smaller islands — that stretches from southern British Columbia up into Alaska and the Yukon. These bits of islands on the move arrived from the Late Cretaceous through the Eocene — and continues to this day.

The rocks that form the Insular Superterrane are allochthonous, meaning they are not related to the rest of the North American continent. The rocks we walk over along the Trent River are distinct from those we find throughout the rest of Vancouver Island, Haida Gwaii, the rest of the province of British Columbia and completely foreign to those we find next door in Alberta.

To discover what we do find on the Trent takes only a wee stroll, a bit of digging and time to put all the pieces of the puzzle together. The first geological forays to Vancouver Island were to look for coal deposits, the profitable remains of ancient forests that could be burned to the power industry.

Jim Monger and Charlie Ross of the Geological Survey of Canada both worked to further our knowledge of the complex geology of the Comox Basin. They were at the cutting edge of west coast geology in the 1970s. It was their work that helped tease out how and where the rocks we see along the Trent today were formed and made their way north.

We know from their work that by 85 million years ago, the Insular Superterrane had made its way to what is now British Columbia.

The lands were forested much as they are now but by extinct genera and families. The fossil remains of trees similar to oak, poplar, maple and ash can be found along the Trent and Vancouver Island. We also see the lovely remains of flowering plants such as Cupanities crenularis, figs and breadfruit.

Heading up the river, you come to a delineation zone that clearly marks the contact between the dark grey marine shales and mudstones of the Haslam Formation where they meet the sandstones of the Comox Formation. Fossilized material is less abundant in the Comox sandstones but still contains some interesting specimens. Here you begin to see fossilized wood and identifiable fossil plant material.

Further upstream, there is a small tributary, Idle Creek, where you can find more of this terrestrial material in the sandy shales. As you walk up, you see identifiable fossil plants beneath your feet and jungle-like, overgrown moss-covered, snarly trees all around you.

Walking west from the Trent River Falls at the bottom, you pass the infamous Ammonite Alley, where you can find Mesopuzosia sp. and Kitchinites sp. of the Upper Cretaceous (Santonian), Haslam Formation. Minding the slippery green algae covering some of the river rocks, you can see the first of the Polytychoceras vancouverense zone.

Continuing west, you reach the first of two fossil turtle sites on the river — amazingly, one terrestrial and one marine. If you continue, you come to the Inland Island Highway.

The Trent River has yielded some very interesting marine specimens, and significant terrestrial finds. We have found a wonderful terrestrial helochelydrid turtle, Naomichelys speciosa, and the caudal vertebrae of a Hadrosauroid dinosaur. Walking down from the Hadrosaur site you come to the site of the fossil ratfish find — one of the ocean's oddest fish.

Ratfish, Hydrolagus Collie, are chimaera found in the north-eastern Pacific Ocean today. The fossil specimen from the Trent would be considered large by modern standards as it is a bruiser in comparison to his modern counterparts.

This robust fellow had exceptionally large eyes and sex organs that dangled enticingly between them. You mock, but there are many ratfish who would differ. While inherently sexy by ratfish standards, this fellow was not particularly tasty to their ancient marine brethren (or humans today) — so not hugely sought after as a food source or prey.

A little further again from the ratfish site we reach the contact of the two Formations. The rocks here have travelled a long way to their current location. With them, we peel away the layers of the geologic history of both the Comox Valley and the province of British Columbia.

The Trent River is not far from the Puntledge, a river whose banks have also revealed many wonderful fossil specimens. The Puntledge is also the name used by the K'ómoks First Nation to describe themselves. They have lived here since time immemorial. Along with Puntledge, they refer to themselves as Sahtloot, Sasitla and Ieeksun.

Directions: If you're keen to explore the area, park on the side of Highway 19 about three kilometres south of Courtenay and hike up to the Trent River. Begin to look for parking about three kilometres south of the Cumberland Interchange. There is a trail that leads from the highway down beneath the bridge which will bring you to the Trent River's north side.

ORTHOCONE: STRAIGHT-SHELLED NAUTILOIDS

Orthocone Nautiloid Fossil

An orthocone is an unusually long, straight shell of a nautiloid cephalopod. You have likely seen them from Ontario or Morocco. These straight-shelled nautiloids rules our seas during the Ordovician, nothing else was even close in size to them.

To put that into context, they would have been more than two times longer than the tallest person you know.

During the 18th and 19th centuries, all shells of this type were named Orthoceras, creating a wastebasket taxon, but it is now known that many groups of nautiloids developed or retained this type of shell.

An orthocone can be thought of as a nautilus but with a pencil-straight, uncoiled shell. You have likely seen living nautilus in the sea if you are very lucky or on social media, if your curiosity has you streaming cephalopod posts. Living nautilus are chunky and coiled with a wee squid-like body living within their shells that they use for protection and the air within for buoyancy to move through the water. Their ancestors were not dissimilar. For a long while, we thought that these marine lovelies represented the most primitive form of nautiloid, but we now know that the earliest nautiloids had shells that were slightly curved.

An orthoconic form evolved several times amongst cephalopods. Amongst nautiloid cephalopods, we
see this in the primitive ellesmerocerids, the endocerids — apex predators of the Ordovician who dined on trilobites, molluscs and brachiopods, in the generally straight-shelled actinocerids, the orthoceratoids (perhaps the last unexplored wilderness in the Cephalopoda).

Orthocone Fossil

We see this form again in the rather smallish order bactritids (relatively speaking within the vast array of the Class Cephalopoda).

These lovely straight-shelled fossils are found in Late Cambrian to Late Triassic outcrops but they were most common in the early Paleozoic. Revivals of the orthocone design later occurred in other cephalopod groups, notably baculitid ammonites in the Cretaceous Period.

Orthocone nautiloids range in size from wee little fellas less than 25 mm (1 in) to a massive 5.2 metres or 17 feet long in the case of the giant endocerids of the Ordovician. Never underestimate just how large a cephalopod can get. If our oceans remain fertile, I expect we'd see one larger than a city block one day.

THE RHINO AND THE GREAT DEPRESSION

c6-vES6ZOCyry00iw-Lh-rOS2PcCINRlCF0H7yl-Z6LLWGZRgySHA4G12X_EwS-lfBbTTY79cva=s6000" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;">

The Miocene pillow basalts from the Lake Roosevelt National Recreation Area of central Washington hold an unlikely fossil.

What looks to be a rather unremarkable ballooning at the top of a cave is actually the mould of a small rhinoceros, preserved by sheer chance as its bloated carcass sunk to the bottom of a shallow lake just prior to a volcanic explosion.

We have known about this gem for a long while now. The fossil was discovered by hikers back in 1935 and later cast by the University of California palaeontologists in 1948.

The Dirty Thirties & The Great Depression

These were the Dirty Thirties and those living in Washington state were experiencing the Great Depression along with the rest of the country and the world. Franklin D. Roosevelt was President of the United States, navigating the States away from laissez-faire economics.

Charmingly, Roosevelt would have his good name honoured by this same park in April of 1946, a few years before researchers at Berkeley would rekindle interest in the site.

Both hiking and fossil collecting was a fine answer to these hard economic times and came with all the delights of discovery with no cost for natural entertainment. And so it was that two fossil enthusiast couples were out looking for petrified wood just south of Dry Falls on Blue Lake in Washington State.

While searching the pillow basalt, the Frieles and Peabodys came across a large hole high up in a cave that had the distinctive shape of an upside-down rhinoceros.

This fossil is interesting in all sorts of ways. First, we so rarely see fossils in igneous rocks. As you might suspect, both magma and lava are very hot. Magma, or molten rock, glows a bright red/orange as it simmers at a toasty 700 °C to 1300 °C (or 1300 °F to 2400 °F) beneath the Earth's surface.

A Rhinoceros Frozen in Lava

During the late Miocene and early Pliocene, repeated basaltic lava floods engulfed about 63,000 square miles of the Pacific Northwest over a period of ten to fifteen million years. After these repeated bathings the residual lava accumulated to more than 6,000 feet.

As magma pushes up to the surface becoming lava, it cools to a nice deep black. In the case of our rhino friend, this is how this unlikely fellow became a fossil. Instead of vaporizing his remains, the lava cooled relatively quickly preserving his outline as a trace fossil and remarkably, a few of his teeth, jaw and bones. The lava was eventually buried then waters from the Spokane Floods eroded enough of the overburden to reveal the remains once more.

Diceratherium tridactylum (Marsh, 1875)

Diceratherium (Marsh, 1875) is known from over a hundred paleontological occurrences from eighty-seven collections.

While there are likely many more, we have found fossil remains of Diceratherium, an extinct genus of rhinoceros, in the Miocene of Canada in Saskatchewan, China, France, Portugal, Switzerland, and multiple sites in the United States.

He has also been found in the Oligocene of Canada in Saskatchewan, and twenty-five localities in the United States — in Arizona, Colorado, Florida, Nebraska, North Dakota, Oregon, South Dakota, Washington and Wyoming.

Diceratherium was a scansorial insectivore with two horns and a fair bit of girth. He was a chunky fellow, weighing in at about one tonne (or 2,200 lbs). That is about the size of a baby Humpback Whale or a walrus.

Back in the Day: Washington State 15 Million-Years Ago

He roamed a much cooler Washington state some 15 million years ago. Ice dams blocked large waterways in the northern half of the state, creating reservoirs. Floodwaters scoured the eastern side of the state, leaving scablands we still see today. In what would become Idaho, volcanic eruptions pushed through the Snake River, the lava cooling instantly as it burst to the surface in a cloud of steam.

By then, the Cascades had arrived and we had yet to see the volcanic eruptions that would entomb whole forests up near Vantage in the Takama Canyon of Washington state.

Know Before You Go

You are welcome to go see his final resting site beside the lake but it is difficult to reach and comes with its own risks. Head to the north end of Blue Lake in Washington. Take a boat and search for openings in the cliff face. You will know you are in the right place if you see a white "R" a couple hundred feet up inside the cliff. Inside the cave, look for a cache left by those who've explored here before you. Once you find the cache, look straight up. That hole above you is the outline of the rhino.

If you don't relish the thought of basalt caving, you can visit a cast of the rhino at the Burke Museum in Seattle, Washington. They have a great museum and are pretty sporting as they have built the cast sturdy enough for folk to climb inside.

The Burke Museum

The Burke Museum recently underwent a rather massive facelift and has re-opened its doors to the public. You can now explore their collections in the New Burke, a 113,000 sq. ft. building at 4300 15th Ave NE, Seattle, WA 98105, United States. Or visit them virtually, at https://www.burkemuseum.org/

Lincoln, Roosevelt and Recovery from The Great Depression

Rural Tennessee has electricity for the same reason Southeast Alaska has totem parks. In order to help the nation recover from The Great Depression, President Franklin D. Roosevelt, created a number of federal agencies to put people to work. From 1938-1942 more than 200 Tlingit and Haida men carved totem poles and cleared land for the Civilian Conservation Corps in an effort to create “totem parks” the federal government hoped would draw travelers to Alaska.

This odd intersection of federal relief, Alaska Native art and marketing is the subject of Emily L. Moore’s book “Proud Raven, Panting Wolf: Carving Alaska’s New Deal Totem Parks.”

This effort to bring poles out of abandoned villages includes the Lincoln Pole being moved to Saxman Totem Park by the Civilian Conservation Corps (CCC), who established the Saxman Totem Park in 1938.

The top carving on the Lincoln Pole bears a great likeness of Abraham Lincoln. According to the teachings of many Tlingit elders, this carving was meant to represent the first white man seen in Tlingit territory in the 18th century.

A century later, in the 1880s, one of my ancestors from the Gaanax.ádi Raven clan of the Tongass Tlingit commissioned the pole to commemorate our ancestor's pride to have seen this first white man—which has become a Gaanax.ádi crest—using a photograph of Abraham Lincoln as the model.

It is important not only for these various readings of the crests but also because it claims Gaanax.ádi clan territory before the first Europeans and budding Americans came to these shores—territory that Tlingit carvers who were re-carving the pole in the 1940s were trying to assert to the U.S. government as sovereign land.

Interestingly, another pole in that same park is the Dogfish Pole, carved for Chief Ebbits Andáa, Teikweidi, Valley House. The Chief Ebbits Memorial Pole—the Dogfish Kootéeyaa Pole—was raised in 1892 in Old Tongass Village in honour of a great man, Head Chief of the Tongass and my ancestor. It was then moved, re-carved and re-painted at Saxman Totem Park in 1938 as part of Roosevelt's program—and it due to be re-carved again this year.

It tells the story of his life and the curious way he became Ebbits as he was born Neokoots. He met and traded with some early American fur traders. One of those traders was a Mister Ebbits. The two became friends and sealed that friendship with the exchanging of names.

If you would like to read more about that pole and others, I recommend, The Wolf and the Raven, by anthropologist Viola Garfield and architect Linn Forrest (my talented cousin), published in 1961 and still in print as I ordered a copy for a friend just this year.

Nevada is a wonderful place to explore our palaeontological history. The state spans a broad spectrum of exposures showcasing the depth of geologic time. It is an interesting cross-section of young and old — and interestingly, a lovely comparison to the Triassic outcrops in British Columbia.

Exposures of the Upper Triassic, Early Norian, Kerri zone, Luning formation, West Union Canyon, just outside Berlin-Ichthyosaur State Park, Nevada.

The Berlin-Ichthyosaur State Park in central Nevada is a very important locality for the understanding of the Carnian-Norian boundary (CNB) in North America.

Rich ammonoid faunas from this site within the Luning Formation were studied by Silberling (1959) and provided 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. Despite its importance, no further investigations have been done at this site during the last 50 years.

Jim Haggart, Mike Orchard and Paul Smith collaborated on a project that took them down to Nevada to look at the conodonts and ammonoids; the group then 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.

They conducted a bed-by-bed sampling of ammonoids and conodonts in West Union Canyon during October 2010. 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.

Ammonoids of the Luning Formation

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.

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 the coeval faunas of the Tethys and Canada.

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

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 had 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.

HORNBY ISLAND'S GLORIOUS FOSSILS

Diplomoceras sp.

This gorgeous cream and brown big beast of a heteromorph, Diplomoceras (Diplomoceras) sp., (Hyatt, 1900) was found within the 72 million-year-old sediments of the upper Nanaimo Group on the northern Gulf Island of Hornby in southwestern British Columbia, Canada.

The site is known as Boulder Point to the locals and it has been a popular fossil destination for many years. It is the home of the K'ómoks First Nation, who called the island Ja-dai-aich.

Many of the fossils found at this locality are discovered in concretions rolled smooth by time and tide. The concretions you find on the beach are generally round or oval in shape and are made up of hard, compacted sedimentary rock.

If you are lucky, when you split these nodules you are rewarded with a fossil hidden within. That is not always the case but the rewards are worth the effort.

These past few years, many new and wonderful specimens have been unearthed — particularly by members of the Vancouver Island Palaeontological Society.

And so it was in the first warm days of early summer last year. Three members of the Vancouver Palaeontological Society excavated this 100 cm long fossil specimen over two days in June of 2020. The specimen was not in concretion but rather embedded in the hard sintered shale matrix beneath their feet. It was angled slightly downward towards the shoreline and locked within the rolling shale beds of the island.

Diplomoceratidae (Spath, 1926) are often referred to as the paperclip ammonites. They are in the family of ammonites included in the order Ammonitida in the Class Cephalopoda and are found within marine offshore to shallow subtidal Cretaceous — 99.7 to 66.043 million-year-old — sediments worldwide.

I was reading with interest this morning about a new find published by Muramiya and Shigeta in December 2020 of a new heteromorph ammonoid Sormaites teshioensis gen. et sp. nov. (Diplomoceratidae) described from the upper Turonian (Upper Cretaceous) in the Nakagawa area, Hokkaido, northern Japan.

This lovely has a shell surface ornamented with simple, straight, sharp-tipped ribs throughout ontogeny, but infrequent flared ribs and constrictions occur on later whorls. Excluding its earliest whorls, its coiling and ornamentation are very similar to Scalarites mihoensis and Sc. densicostatus from the Turonian to Coniacian in Hokkaido and Sakhalin, suggesting that So. teshioensis was probably derived from one of these taxa in the Northwest Pacific during middle to late Turonian.

Much like the long-lived geoducks living in Puget Sound today, studies of Diplomoceras suggest that members of this family could live to be over 200 years old — a good 40-years longer than a geoduck but not nearly as long-lived as the extant bivalve Arctica islandica that reach 405 to 410 years in age.

Along with this jaw-dropper of a heteromorph, the same group found an Actinosepia, gladius — internal hard body part found in many cephalopods of a Vampyropod. Vampyropods are members of the proposed group Vampyropoda — equivalent to the superorder Octopodiformes — which includes vampire squid and octopus.

The upper Nanaimo Group is a mix of marine sandstone, conglomerate and shale. These are partially exposed in the Campanian to the lower Maastrichtian outcrops at Collishaw Point on the northwest side of Hornby Island.

Along with fossil crabs, shark teeth, bivalves and occasional rare and exquisite saurodontid fish, an ambush predator with very sharp serrated teeth and elongate, torpedo-like body — we also find three heteromorph ammonite families are represented within the massive, dark-grey mudstones interlaminated and interbedded with siltstone and fine-grained sandstone of the upper Campanian (Upper Cretaceous) strata of the Northumberland Formation exposed here: Baculitidae, Diplomoceratidae and Nostoceratidae.

A variety of species are distinguished within these families, of which only three taxa – Baculites occidentalis (Meek, 1862), Diplomoceras (Diplomoceras) cylindraceum (Defrance, 1816) and Nostoceras (Nostoceras) hornbyense (Whiteaves, 1895), have been studied and reported previously.

Over the last decade, large new collections by many members of the Vancouver Island Palaeontological Society and palaeontologists working at the Geologic Survey of Canada, along with a renewed look at previous collections have provided new taxonomic and morphometric data for the Hornby Island ammonite fauna. This renewed lens has helped shape our understanding and revamp descriptions of heteromorph taxa. Eleven taxa are recognized, including the new species Exiteloceras (Exiteloceras) densicostatum sp. nov., Nostoceras (Didymoceras?) adrotans sp. nov. and Solenoceras exornatus sp. nov.

A great variety of shape and form exist within each group. Morphometric analyses by Sandy McLachlan and Jim Haggart of over 700 specimens unveiled the considerable phenotypic plasticity of these ammonites. They exhibit an extraordinarily broad spectrum of variability in their ornamentation and shell dimensions.

The presence of a vibrant—and deeply awesome—palaeontological community on Vancouver Island made the extent of their work possible.

Graham Beard, Doug Carrick, Betty Franklin, Raymond Graham, Joe Haegert, Bob Hunt, Stevi Kittleson, Kurt Morrison and Jean Sibbald are thanked for their correspondence and generosity in contributing many of the exquisite specimens featured in that study.

These generous individuals, along with many other members of the Vancouver Island Palaeontological Society (VIPS), Vancouver Paleontological Society (VanPS), and British Columbia Paleontological Alliance (BCPA), have contributed a great deal to our knowledge of the West Coast of Canada and her geologic and palaeontological correlations to the rest of the world; notably, Dan Bowen, Rick Ross, John Fam and Pat and Mike Trask, Naomi & Terry Thomas. Their diligence in the collection, preparation and documentation of macrofossils is a reflection of the passion they have for palaeontology and their will to help shape the narrative of Earth history.

Through their efforts, a large population sample of Nostoceras (Nostoceras) hornbyense was made available and provided an excellent case study of a member of the Nostoceratidae. It was through the well-documented collection and examination of a remarkable number of nearly complete, well-preserved specimens that a re-evaluation of diagnostic traits within the genus Nostoceras was made possible.

The north-east Pacific Nostoceras (Nostoceras) hornbyense Zone and the global Nostoceras (Nostoceras) hyatti Assemblage Zone are regarded as correlative, reinforcing a late Campanian age for the Northumberland Formation. This builds on the earlier work of individuals like Alan McGugan and others. McGugan looked at the Upper Cretaceous (Campanian and Maastrichtian) Foraminifera from the Upper Lambert and Northumberland Formations, Gulf Islands, British Columbia, Canada.

The Maastrichtian Bolivina incrassata fauna (upper part of Upper Lambert Formation) of Hornby Island (northern Comox Basin) is now recognized in the southern Nanaimo Basin on Gabriola and Galiano Islands. The Maastrichtian planktonic index species Globotruncana contusa occurs in the Upper Northumberland Formation of Mayne Island and Globotruncana calcarata (uppermost Campanian) occurs| in the Upper Northumberland Formation of Mayne Island and also in the Upper Lambert Formation at Manning Point on the north shore of Hornby Island (Comox Basin).

Very abundant benthonic and planktonic foraminiferal assemblages from the Upper Campanian Lower Northumberland Formation of Mayne Island enable paleoecological interpretations to be made using the Fisher diversity index, triangular plots of Texturlariina/Rotaliina/Miliolina, calcareous/agglutinated ratios, planktonic/benthonic ratios, generic models, and associated microfossils and megafossils.

Combined with local geology and stratigraphy a relatively shallow neritic depositional environment is proposed for the Northumberland Formation in agreement with Scott but not Sliter who proposed an Outer shelf/slope environment with depths of 300 m or more.

VANCOUVER ISLAND'S FABULOUS FOSSILS: TRENT RIVER PALAEONTOLOGY

Dan Bowen, Chair, VIPS, Trent River

The rocks that make up the Trent River on Vancouver Island are on the move. They were laid down near of the equator as small, tropical islands. They rode across the Pacific heading north and slightly east over the past 85 million years to where we find them today.

We know from their work that by 85 million years ago, the Insular Superterrane had made its way to what is now British Columbia.

Continuing west, you reach the first of two fossil turtle sites on the river — amazingly, one terrestrial and one marine. If you continue, you come to the Inland Island Highway.

BUMBLEBEES: HAMDZALAT'SI

This fuzzy yellow and black striped fellow is a bumblebee in the genus Bombus sp., family Apidae. We know him from our gardens where we see them busily lapping up nectar and pollen from flowers with their long hairy tongues.

My Norwegian cousins on my mother's side call them humle. Norway is a wonderful place to be something wild as the wild places have not been disturbed by our hands.

There are an impressive thirty-five species of bumblebee species that call Norway hjem (home), and one, Bombus consobrinus, boasts the longest tongue that they use to feast solely on Monkshood, genus Aconitum, you may know by the name Wolf's-bane.

In the Kwak̓wala language of the Kwakwaka'wakw, speakers of Kwak'wala, and my family in the Pacific Northwest, bumblebees are known as ha̱mdzalat̕si — though I wonder if this is actually the word for a honey bee, Apis mellifera, as ha̱mdzat̕si is the word for a beehive.

I have a special fondness for all bees and look for them both in the garden and in First Nation art.

Bumblebees' habit of rolling around in flowers gives us a sense that these industrious insects are also playful. In First Nation art they provide levity — comic relief along with their cousins the mosquitoes and wasps — as First Nation dancers wear masks made to mimic their round faces, big round eyes and pointy stingers. A bit of artistic license is taken with their forms as each mask may have up to six stingers. The dancers weave amongst the watchful audience and swoop down to playfully give many of the guests a good, albeit gentle, poke.

Honey bees actually do a little dance when they get back to the nest with news of an exciting new place to forage — truly they do. Bumblebees do not do a wee bee dance when they come home pleased with themselves from a successful foraging mission, but they do rush around excitedly, running to and fro to share their excitement. They are social learners, so this behaviour can signal those heading out to join them as they return to the perfect patch of wildflowers.

Bumblebees are quite passive and usually sting in defence of their nest or if they feel threatened. Female bumblebees can sting several times and live on afterwards — unlike honeybees who hold back on their single sting as its barbs hook in once used and their exit shears it off, marking their demise.

They are important buzz pollinators both for our food crops and our wildflowers. Their wings beat at 130 times or more per second, literally shaking the pollen off the flowers with their vibration.

And they truly are busy bees, spending their days fully focused on their work. Bumblebees collect and carry pollen and nectar back to the nest which may be as much as 25% to 75% of their body weight.

And they are courteous — as they harvest each flower, they mark them with a particular scent to help others in their group know that the nectar is gone.

The food they bring back to the nest is eaten to keep the hive healthy but is not used to make honey as each new season's queen bees hibernate over the winter and emerge reinvigorated to seek a new hive each Spring. She will choose a new site, primarily underground depending on the bumblebee species, and then set to work building wax cells for each of her fertilised eggs.

Bumblebees are quite hardy. The plentiful hairs on their bodies are coated in oils that provide them with natural waterproofing. They can also generate more heat than their smaller, slender honey bee cousins, so they remain productive workers in cooler weather.

We see the first bumblebees arise in the fossil record 100 million years ago and diversify alongside the earliest flowering plants. Their evolution is an entangled dance with the pollen and varied array of flowers that colour our world.

We have found many wonderful examples within the fossil record, including a rather famous Eocene fossil bee found by a dear friend and naturalist who has left this Earth, Rene Savenye.

His namesake, H. Savenyei, is a lovely fossil halictine bee from Early Eocene deposits near Quilchena, British Columbia — and the first bee body-fossil known from the Okanagan Highlands — and indeed from Canada.

It is a fitting homage, as bees symbolize honesty, playfulness and willingness to serve the community in our local First Nation lore and around the world — something Rene did his whole life.

CHIRPING THERMOMETERS

About 250 million years ago, our once silent world became a cacophony of diverse animal sounds.

One of the most lyrical of those voices to join the Earth's chorus were the true crickets. We can count them as some of the earliest musicians on the planet.

This group evolved and contributed to the nocturnal circumambience of our planet a full 150 million years before our human ancestors would have heard them for the very first time. It is their long lineage that I am mindful of when I am out for an evening stroll and hear their pleasing serenade.

If you find yourself out in the woods and are wondering what the temperature might be, you need only slip closer to the nearest stand of deciduous trees to follow the musical sounds of the wee Snowy Tree Cricket, Oecanthus Fultoni, part of the order orthoptera.

Snowy Tree Crickets and their cousins double as thermometers and wee garden predators, dining on aphids and other wee beasties. Weather conditions, both hot and cold, alter the speed at which they rub the base of their wings together and consequently regulate their rate of chirping.

Listen closely for their tell-tale high pitch triple chirp sound in the early evening. Being in Canada, our crickets chirp in Celsius. To figure out the temperature, we simply count the number of chirps over a seven-second period and add five to learn the local temperature.

If did not happen to bring your calculator and you are still operating in old-school Fahrenheit, you can use this handy conversion — double the temperature in Celsius, add 32 you'll get the approximate temperature in Fahrenheit. And if you are not all that interested in the temperature, enjoy their pleasing serenade as you take your early evening stroll. They've been working on this number for millions of years.

Daniel Otte from the Academy of Natural Sciences in Philadelphia did up a wonderful piece on the evolution of cricket songs. If you’re a keen bean & want to learn more, I'll attach the journal article for you. https://doi.org/10.2307/3503559. https://www.jstor.org/stable/3503559

EXPLORING THE GLORIOUS KOOTENAY REGION

The East Kootenay region on the south-eastern edge of British Columbia is a land of colossal mountains against a clear blue sky.

That is not strictly true, of course, as this area does see its fair share of rain and temperature extremes — but visiting in Autumn every view is a postcard of mountainous terrain.

Rocks from deep within the Earth's crust underlie the entire East Kootenay region and are commonly exposed in the areas majestic mountain peaks, craggy rocky cliffs, glaciated river canyons, and rock cuts along the highways. Younger Ice Age sediments blanket much of the underlying rock.

I've been heading to the Cranbrook and Fernie area since the early 1990s. My interest is the local geology and fossil history that these rocks have to tell. I'm also drawn to the warm and welcoming locals who share a love for the land and palaeontological treasures that open a window to our ancient past.

Cranbrook is the largest community in the region and is steeped in mining history and the opening of the west by the railway. It is also a stone's throw away from Fort Steele and the Lower Cambrian exposures of the Eager Formation. These fossil beds rival the slightly younger Burgess Shale fauna and while less varied, produce wonderful examples of olenellid trilobites and weird and wonderful arthropods half a billion years old.

Labiostria westriopi, McKay Group

The Lower Cambrian Eager Formation outcrops at a few localities close to Fort Steele, many known since the early 1920s, and up near Mount Grainger near the highway.

Further east, the Upper Cambrian McKay Group near Tanglefoot Mountain is a palaeontological delight with fifteen known outcrops that have produced some of the best-preserved and varied trilobites in the province — many of them new species.

The McKay Formation also includes Ordovician outcrops sprinkled in for good measure.

Other cities in the area and the routes to and from them produce other fossil fauna from Kimberley to Fernie and the district municipality of Invermere and Sparwood. This is an arid country with native grasslands and forests of semi-open fir and pine. Throughout there are a host of fossiliferous exposures from Lower Cretaceous plants to brachiopods.

The area around Whiteswan Lake has wonderful large and showy Ordovician graptolites including Cardiograptus morsus and Pseudoclimacograptus angustifolius elongates — some of our oldest relatives. A drive down to Flathead will bring you to ammonite outcrops and you can even find Eocene fresh-water snails in the region.

The drive from Cranbrook to Fernie is about an hour and change through the Cambrian into the Devonian which flip-flops and folds over revealing Jurassic exposures.

Fernie Ichthyosaur Excavation, 1916

The Crowsnest Highway into Fernie follows Mutz Creek. From the highway, you can see the Fernie Group and the site along the Elk River where an ichthyosaur was excavated in 1916.

The Fernie Formation is Jurassic. It is present in the western part of the Western Canada Sedimentary Basin in western Alberta and northeastern British Columbia.

It takes its name from the town of Fernie, British Columbia, and was first defined by W.W. Leach in 1914. The town of Fernie is rimmed by rugged mountains tipped with Devonian marine outcrops. In essence, all these mountains are upside down with the oldest layers flipped to the top and a good 180 million years older than those they sit upon.

Before they were mountains, these sedimentary rocks were formed as sediment collected in a shallow sea or inland basin. About 360 million years ago, the rocks that you see in Fernie today were down near the equator. They road tectonic plates, pushing northeast smashing into the coastline of what would become British Columbia. A little push here, shove there — compression and thrust faulting — and the rock was rolled over on its head — repeatedly. But that is how mountains are often formed, though not usually pushed so hard that they flip over. But still, it is a slow, relentless business.

Cretaceous Plant Material, Fernie, BC

Within Fernie, there are small exposures of Triassic and Jurassic marine outcrops. East of the town there are Cretaceous plant sites, and of course, the Jurassic 1.4-metre Titanites occidentalis ammonite up on Coal Mountain.

The regional district's dominant landform is the Rocky Mountain Trench, which is flanked by the Purcell Mountains and the Rocky Mountains on the east and west, and includes the Columbia Valley region. The southern half of which is in the regional district — its northern half is in the Columbia-Shuswap Regional District.

The regional district of Elk Valley in the southern Rockies is the entryway to the Crowsnest Pass and an important coal-mining area.

Other than the Columbia and Kootenay Rivers, whose valleys shape the bottomlands of the Rocky Mountain Trench, the regional districts form the northernmost parts of the basins of the Flathead, Moyie and Yahk Rivers.

The Moyie and Yahk are tributaries of the Kootenay, entering it in the United States, and the Flathead is a tributary of the Clark Fork into Montana.

FERNIE'S GIANT AMMONITE: TITANITES

Titanites occidentalis, Fernie Ammonite

The Fernie ammonite, Titanites occidentalis, from outcrops on Coal Mountain near Fernie, British Columbia, Canada.

This beauty is the remains of a carnivorous cephalopod within the family Dorsoplanitidae that lived and died in a shallow sea some 150 million years ago.

If you would like to get off the beaten track and hike up to see this ancient beauty, you will want to head to the town of Fernie in British Columbia close to the Alberta border.

This is the traditional territory of the the Yaq̓it ʔa·knuqⱡi ‘it First Nation who have lived here since time immemorial. There was some active logging along the hillside in 2021, so if you are looking at older directions on how to get to the site be mindful that many of the trailheads have been altered and a fair bit of bushwhacking will be necessary to get to the fossil site proper. That being said, the loggers from CanWel may have clear-cut large sections of the hillside but they did give the ammonite a wide berth and have left it intact.

Wildsight, a non-profit environmental group out of the Kimberly Cranbrook area has been trying to gain grant funding to open up the site as an educational hike with educational signage for folks visiting the Fernie area. It is likely the province of British Columbia would top up those funds if they are able to place the ammonite under the Heritage Conservation Act. CanWel would remain the owners of the land but the province could assume the liability for those visiting this iconic piece of British Columbia's palaeontological history.

Driving to the trail base is along an easy access road just east of town along Fernie Coal Road. There are some nice exposures of Cretaceous plant material on the north side (left-hand side) of the road as you head from Fernie towards Coal Creek. I recently drove up to Fernie to look at Cretaceous plant material and locate the access point to the now infamous Late Jurassic (Tithonian) Titanites (S.S. Buckman, 1921) site. While the drive out of town is on an easy, well-maintained road, the slog up to the ammonite site is often a wet, steep push. This time of year, it is buried in a blanket of crisp, white snow.

Fernie, British Columbia, Canada

The first Titanites occidentalis was about one-third the size and was incorrectly identified as Lytoceras, a fast-moving nektonic carnivore. The specimen you see here is significantly larger at 1.4 metres (about four and a half feet) and rare in North America.

Titanites occidentalis, the Western Giant, is the second known specimen of this extinct fossil species.

The first was discovered in 1947 in nearby Coal Creek by a British Columbia Geophysical Society mapping team. When they first discovered this marine fossil high up on the hillside, they could not believe their eyes — both because it is clearly marine at the top of a mountain and the sheer size of this ancient beauty.

In the summer of 1947, on a warm summer's day, a field crew was mapping coal outcrops for the BC Geological Survey (GSC) east of Fernie. One of the students reported finding “a fossil truck tire.” Fair enough. The similarity of size and optics are pretty close to your average Goodridge.

A few years later, GSC Paleontologist Hans Frebold described and named the fossil Titanites occidentalis after the large Jurassic ammonites from Dorset, England. The name comes from Greek mythology. Tithonus, as you may recall, was the Prince of Troy. He fell in love with Eos, the Greek Goddess of the Dawn. Eos begged Zeus to make her mortal lover immortal. Zeus granted her wish but did not grant Tithonus eternal youth. He did indeed live forever — ageing hideously. Ah, Zeus, you old trickster. It is a clever play on time placement. Dawn is the beginning of the day and the Tithonian being the latest age of the Late Jurassic. Clever Hans!

HIKING TO THE FERNIE AMMONITE

From the town of Fernie, British Columbia, head east along Coal Creek Road towards Coal Creek. The site is 3.81 km from the base of Coal Creek Road to the trailhead as the crow flies. I have mapped it here for you in yellow and added the wee purple GPS marker for the ammonite site proper. There is a nice, dark grey to black roadcut exposure of Cretaceous plants on the north side of the dirt road that is your cue to pull over and park.

You access what is left of the trailhead on the south side of the road. You will need to cross the creek to begin your ascent. There is no easy way across the creek and you'll want to tackle this one with a friend when the water level is low.

The beginning of the trail is not clear but a bit of searching will reveal the trailhead with its telltale signs of previous hikers. This is a moderate 6.3-kilometre hike up & back bushwhacking through scrub and fallen trees. Heading up, you will make about a 246-metre elevation gain. You will likely not have a cellular signal up here but if you download the Google Map to your mobile, you will have GPS to guide you. The area has been recently logged so much of the original trail has been destroyed. There may now be easier vehicle access up the logging roads but I have not driven them since the logging and new road construction.

If you are coming in from out of town, the closest airport is Cranbrook. Then it is about an hour and change to Fernie and another 15-minutes or so to park near the site.

You will want to leave your hammers with your vehicle (no need to carry the weight and this lovely should never be struck with anything more than a raindrop) as this site is best enjoyed with a camera.

This is a site you will want to wear hiking boots to access. Know that these will get wet as you cross the creek.

If you would like to see the ammonite but are not keen on the hike, a cast has been made by fossil preparator Rod Bartlett is on display at the Courtenay Museum in Courtenay, Vancouver Island, Canada.

Respect for the Land / Leave No Trace

As your feet move up the hillside, you can imagine this land 10,000 years ago, rising above great glaciers. Where footfalls trace the steps of those that came before you. This land has been home to the Yaq̓it ʔa·knuqⱡi ‘it First Nation and Ktunaxa or Kukin ʔamakis First Nations whose oral history have them living here since time immemorial. Like them, take only what you need and no more than the land offers — packing out anything that you packed in.

FOSSIL TETRAPODS FROM THE ARCTIC

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!
