MASSIVE AMMONITE FROM MADAGASCAR

This big beastie is a superb specimen of the ammonite Lobolytoceras costellatum showing the intricate fractal pattern of its septa. 

This lovely measures to a whopping 230 mm and hails from Oxfordian outcrops near Sakara, Madagascar. Lovingly prepped by the supremely talented José Juárez Ruiz.

Ammonites were predatory, squidlike creatures that lived inside coil-shaped shells. Like other cephalopods, ammonites had sharp, beak-like jaws inside a ring of squid-like tentacles that extended from their shells. They used these tentacles to snare prey — plankton, vegetation, fish and crustaceans — similar to the way a squid or octopus hunt today.

Catching a fish with your hands is no easy feat, as I'm sure you know. Ammonites did the equivalent, catching prey in their tentacles. They were skilled and successful hunters. They caught their prey while swimming and floating in the water column. 

Within their shells, they had a number of chambers, called septa, filled with gas or fluid that were interconnected by a wee air tube. By pushing air in or out, they were able to control their buoyancy in the water column.

They lived in the last chamber of their shells, continuously building new shell material as they grew. As each new chamber was added, the squid-like body of the ammonite would move down to occupy the final outside chamber.

They were a group of extinct marine mollusc animals in the subclass Ammonoidea of the class Cephalopoda. These molluscs, commonly referred to as ammonites, are more closely related to living coleoids — octopuses, squid, and cuttlefish) then they are to shelled nautiloids such as the living Nautilus species.

Ammonites have intricate and complex patterns on their shells called sutures. The suture patterns differ across species and tell us what time period the ammonite is from. If they are geometric with numerous undivided lobes and saddles and eight lobes around the conch, we refer to their pattern as goniatitic, a characteristic of Paleozoic ammonites.

Ammonites first appeared about 240 million years ago, though they descended from straight-shelled cephalopods called bacrites that date back to the Devonian, about 415 million years ago, and the last species vanished in the Cretaceous–Paleogene extinction event.

They were prolific breeders that evolved rapidly. If you could cast a fishing line into our ancient seas, it is likely that you would hook an ammonite, not a fish. They were prolific back in the day, living (and sometimes dying) in schools in oceans around the globe. We find ammonite fossils (and plenty of them) in sedimentary rock from all over the world.

In some cases, we find rock beds where we can see evidence of a new species that evolved, lived and died out in such a short time span that we can walk through time, following the course of evolution using ammonites as a window into the past.

For this reason, they make excellent index fossils. An index fossil is a species that allows us to link a particular rock formation, layered in time with a particular species or genus found there. Generally, deeper is older, so we use the sedimentary layers rock to match up to specific geologic time periods, rather the way we use tree-rings to date trees. A handy way to compare fossils and date strata across the globe.

BUMBLEBEES, FOSSILS AND FIRST NATIONS

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.

AMYLASE: YOU ARE WHAT YOU EAT

The old adage, you are what you eat, might be best amended to you are what you can digest. 

For all the mammals, you and I included, we need the amylase gene (AMY). It codes for a starch-digesting enzyme needed to break down the vegetation we eat. 

Humans, dogs and mice have record numbers of the amylase gene. The AMY gene copy number increases in mammal populations where starch-based foods are more abundant. Think toast and jam versus raw chicken.

A good example of this is seen when we compare wolves living in the wild to dogs from agricultural societies. Dogs split off the lineage from wolves around 30,000–40,000 years ago. 

Domesticated dogs have extra copies of amylase and other genes involved in starch digestion that contribute to an increased ability to thrive on a starch-rich diet, allowing Fido to make the most of those table scraps. Similar to humans, some dog breeds produce amylase in their saliva, a clear marker of a high starch diet. So do mice, rats, and pigs, as expected as they live in concert with humans. Curiously, so do some New World monkeys, boars, deer mice, woodrats, and giant African pouched rats. 

Miss Coco Bean Surveying Her Realm

More like cats and less like other omnivores, dogs can only produce bile acid with taurine and they cannot produce vitamin D, which they obtain from animal flesh. Also, more like cats, dogs require arginine to maintain their nitrogen balance. These nutritional requirements place dogs halfway between carnivores and omnivores.

The amount of AMY and starch in the diet varies among subspecies, and sometimes even amongst geographically distinct populations of the same species. 

I was at a talk recently given by Alaskan wolf researchers who shared that two individual packs of wolves separated by less than a kilometre ate vastly different diets. This had me thinking about what we eat and it is mostly driven by what is on offer. 

Diet impacts our genetics and this, in turn, allows the fittest to eat, digest and survive. While wolves win the carnivore contest, they will still eat opportunistically and that includes vegetation when other food is scarce. 

Would they evolve similar levels of AMY as humans, dogs and mice? Maybe if their diets evolved to be similar. Likely. The choice would be that or starvation. The evolution of amylase in other domesticated or human commensal mammals remains an alluring area of inquiry.

As for our domesticated friends, they eat what is on offer. Mostly kibble and some table scraps. The cutie above is my girl Coco Bean surveying her realm. She eats a raw diet like her ancestors but scavenged from her dish versus hunting in the wild.

BERLIN-ICHTHYSAUR STATE PARK, NEVADA

Time Slows at Berlin-Ichthyosaur State Park

High on the hillside up a long entry road sits the entrance to Berlin-Ichthyosaur State Park in central Nevada.

A worn American flag and sun bleached outbuildings greet you on your way to the outcrops. Away from the hustle and bustle that define 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 sage brush.

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.

KING OF THE TRILOBITES: UNEARTHING ISOTELUS REX

Isotelus rex, the King of Trilobites

In the remote limestone flats of northern Manitoba, a remarkable fossil lay undisturbed for nearly half a billion years. Sunken in gray stone, its broad armored body preserved in exquisite detail, it waited silently—until a team of Canadian paleontologists happened upon it during a summer field expedition in 1999.

What they uncovered would change the story of trilobites forever.

Meet Isotelus rex, the largest complete trilobite ever discovered—a 70-centimetre-long prehistoric titan from the Ordovician seas. It's more than just a big trilobite. It’s a window into an ancient world and a landmark find in Canadian paleontology.

A Fossil Giant in a Forgotten Sea

Trilobites, extinct marine arthropods, are among the most iconic fossils in the world. Their hard, segmented exoskeletons and alien-like eyes make them favorites among collectors and scientists alike. They first appeared more than 520 million years ago and thrived in Earth’s oceans for over 270 million years before vanishing in the Permian extinction.

Many trilobites are palm-sized or smaller. But Isotelus rex was something else entirely.

Discovered near William Lake in the Hudson Bay Lowlands of Manitoba, Isotelus rex was preserved in limestone laid down when central Canada was submerged beneath a warm, shallow sea. That sea teemed with life—brachiopods, nautiloids, sea lilies, and trilobites like Isotelus, which would have cruised the muddy bottom looking for food.

With its broad, paddle-shaped tail, deeply segmented body, and large compound eyes, Isotelus rex was a slow-moving but imposing presence on the seafloor.

The Paleontologists Behind the Discovery

The discovery was made by a team of seasoned Canadian researchers: Dr. David Rudkin of the Royal Ontario Museum, Dr. Graham Young and Edward Dobrzanske of the Manitoba Museum, and Dr. Robert Elias from the University of Manitoba. 

All were participating in a joint field expedition to study the fossil-rich limestone of the Churchill River Group, near Churchill in northern Manitoba.

Dr. Rudkin is one of Canada’s leading experts on Paleozoic arthropods, with a particular passion for trilobites and other ancient sea creatures. 

His work at the Royal Ontario Museum has helped bring the stories of long-extinct animals to life through detailed study and public exhibition.

Dr. Young, curator of geology and paleontology at the Manitoba Museum, specializes in ancient marine ecosystems—piecing together how life functioned and interacted in prehistoric oceans. 

Dr. Elias, a geologist and paleontologist at the University of Manitoba, focuses on Paleozoic reefs and ancient sedimentary environments. Dobrzanske, a collections technician and field expert, brought deep practical knowledge to the fieldwork.

It was the perfect blend of expertise and passion.

One overcast morning, while surveying outcrops of Ordovician limestone, the team spotted a familiar ripple in the rock—a faint curve suggesting a trilobite’s cephalon, or head shield. As they slowly and carefully uncovered more of the fossil, its remarkable size and completeness became apparent.

The mostly complete holotype specimen of Isotelus rex, from the Churchill River Group, measures a staggering 720 millimetres (28 inches) in length, 400 millimetres (16 inches) in maximum width across the cephalon, and 70 millimetres (3 inches) in height at the posterior midpoint of the head. It remains the largest complete trilobite ever found.

“We thought it might be a fluke,” Rudkin later recalled. “A fragment from a large individual. But as we kept going—it just kept going. That was when we realized we were looking at something truly extraordinary.”

Perfect Conditions for Preservation

Unlike many trilobite fossils, which are found in fragments or disarticulated pieces, Isotelus rex was remarkably well-preserved—fully articulated, lying in life position.

Paleontologists believe it was buried rapidly by fine carbonate mud, likely during a sudden underwater event like a storm or sediment slump. The seafloor at the time was likely anoxic—lacking oxygen—which would have prevented decay and scavenging, allowing the trilobite’s body to remain intact as minerals slowly fossilized it over millions of years.

“It’s one of the most complete large trilobites ever found anywhere in the world,” said Young. “It offers a rare look at what these creatures really looked like, in full form.”

While its size is headline-grabbing, Isotelus rex offers deeper scientific insights. It shows that trilobites—already known for their diversity—could grow far larger than previously thought. Its presence in northern Manitoba also highlights how much of Canada’s paleontological richness remains underexplored.

The fossil was later transported to Winnipeg, where it became a highlight of the Manitoba Museum’s paleontology collection. A custom case was built to display it—regular trilobite mounts just wouldn’t do for a specimen of this scale.

The name Isotelus rex—Latin for “equal end king”—reflects both its classification and its grandeur.

Today, Isotelus rex is more than just a museum centerpiece. It’s a reminder of the power of curiosity, collaboration, and exploration. It represents a frozen moment from 450 million years ago, when trilobites were the dominant animals of Earth’s seas.

And thanks to the eyes, hands, and minds of Rudkin, Elias, Young, and Dobrzanske, we now know what the king of trilobites looked like and he is an impressive specimen, indeed!

BURGESS SHALE FOSSILS: A DEEP TIME JOURNEY IN YOHO NATIONAL PARK

Tucked high in the Canadian Rockies above the tiny hamlet of Field, British Columbia, lies one of the most extraordinary fossil sites on Earth — the Burgess Shale. 

This UNESCO World Heritage site offers a rare and detailed look at life on Earth over half a billion years ago, during a time known as the Cambrian Explosion.

Whether you're a seasoned paleontology buff or a curious traveler, this ancient treasure trove belongs on your bucket list. Here’s everything you need to know about the fossils, the tours, how to get there, where to stay, eat, and explore.

Why Are the Burgess Shale Fossils Important?

The fossils of the Burgess Shale are a paleontological jackpot. Dating back 508 million years, they preserve not just the hard shells and bones, but also the soft tissues of ancient creatures — things like gills, eyes, and guts. These rare details offer a vivid snapshot of life in the ancient Cambrian seas.

Discovered by Charles Doolittle Walcott in 1909, the Burgess Shale holds some of the earliest and weirdest animals to ever live on Earth — including:

• Anomalocaris – a top predator with grasping arms and a ring of teeth
• Opabinia – a creature with five eyes and a long, tube-like nose
• Hallucigenia – a spiny worm that once puzzled scientists with its upside-down anatomy
• Pikaia – one of the first known animals with a notochord, an early precursor to the backbone

These fossils help us understand the roots of animal evolution — including our own.

Guided Fossil Tours: Hike Through Deep Time

Yes — you can actually visit these ancient fossil beds! Parks Canada offers guided day hikes to several Burgess Shale sites during the summer months (late June to early September). All tours must be booked in advance and are mandatory to access these protected areas. You can take photos galore but cannot collect or keep any of the fossils. They are protected and their removal is illegal.

MASSIVE FOSSIL AMMONITE NEAR FERNIE, BRITISH COLUMBIA

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.

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, a field crew was mapping coal outcrops for the BC Geological Survey 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.

ANCIENT SEA MONSTERS: ICHTHYOSAURS AND MOSASAURS

When we think of prehistoric creatures, dinosaurs usually steal the spotlight. But beneath the ancient waves swam giants just as awe-inspiring—and sometimes even more terrifying. 

Among these marine reptiles, two groups stand out: ichthyosaurs and mosasaurs. Though they never coexisted, both ruled the oceans in their own time and in their own terrifying ways.

Ichthyosaurs: Dolphin-Like Reptiles of the Jurassic

Ichthyosaurs (meaning "fish lizards") were sleek, fast swimmers that first appeared around 250 million years ago during the Triassic. 

Their streamlined bodies, long snouts, and large eyes gave them an appearance eerily similar to modern dolphins—though they weren’t mammals. This resemblance is a perfect example of convergent evolution, where unrelated animals develop similar traits to adapt to similar environments.

Some ichthyosaurs grew as long as a school bus, and their enormous eyes (some as large as dinner plates) suggest they were capable of deep-sea hunting. They fed on fish, squid, and other marine life, and some species likely gave birth to live young—a rare trait among reptiles.

They thrived for millions of years but began to decline in the mid-Cretaceous, eventually going extinct before the rise of mosasaurs.

Mosasaurs: Apex Predators of the Cretaceous Seas

Enter the mosasaurs, who rose to dominance after the ichthyosaurs were gone. Mosasaurs appeared around 98 million years ago and ruled the oceans until the mass extinction event 66 million years ago that also wiped out the dinosaurs.

These were true marine lizards, closely related to today’s monitor lizards and snakes. Picture a massive, crocodile-headed Komodo dragon with flippers and a shark-like tail—and you’ll have a good image of a mosasaur. Some species grew over 50 feet long, and their jaws were packed with conical, backward-curving teeth perfect for gripping slippery prey.

Mosasaurs were apex predators, eating anything they could catch—fish, turtles, birds, and even other mosasaurs. Their double-jointed jaws could open wide, allowing them to swallow large prey whole.

Who Would Win in a Fight?

While it’s fun to imagine a battle between an ichthyosaur and a mosasaur, it never could have happened—ichthyosaurs were long extinct by the time mosasaurs evolved. That said, mosasaurs were more heavily built and had powerful jaws, making them formidable hunters. Ichthyosaurs were faster and more agile, more suited to quick chases than brute force.

Legacy Beneath the Waves

Both ichthyosaurs and mosasaurs left behind rich fossil records, giving scientists insight into how reptiles adapted to life in the oceans. Their bones have been found on every continent, including Antarctica, reminding us that the ancient oceans were just as dynamic and dangerous as today’s wildest habitats.

Next time you watch a documentary about dinosaurs or visit a natural history museum, take a moment to appreciate the marine reptiles that once ruled the seas. After all, the land wasn't the only place where prehistoric giants thrived.

MEET UNESCOCERATOPS KOPPELHUSAE

Unescoceratops koppelhusae, Julius Csotonyi

A very sweet small leptoceratopsid dinosaur, Unescoceratops koppelhusae — a new species in the collections of the Royal Tyrrell Museum of Palaeontology in Drumheller, Alberta.

The colourful and beautifully detailed painting you see here is by the very talented Julius Csotonyi who captured the magnificence of form, texture and palette to bring this small leptoceratopsid dinosaur to life.

The Royal Tyrrell Museum of Palaeontology, named in honour of Joseph Burr Tyrrell, is a palaeontology museum and research facility in Drumheller, Alberta, Canada. 

This jaw is the holotype specimen of this small leptoceratopsid dinosaur. Only a handful of isolated fossils have been found from this species, including a jaw that is the holotype specimen now in collections at the Royal Tyrell.

The rusty chocolate jaw bone you see here is the puzzle piece that helped all of the research come together and help us to better understand more about the diminutive leptoceratopsid dinosaurs from Alberta. 

The Cleveland Museum of Natural History's Michael Ryan and David Evans of the Royal Ontario Museum in Toronto recently determined that the specimen was a new genus and species. 

Unescoceratops is a genus of leptoceratopsid ceratopsian dinosaurs known from the Late Cretaceous (about 76.5-75 million years ago) of Alberta, Canada. Unescoceratops is thought to have been between one and two meters long and less than 91 kilograms. A plant-eater, its teeth were the roundest of all Leptocertopsids.

Dinosaur Provincial Park, Alberta, Canada

The genus name acknowledges the UNESCO  World Heritage Site, Dinosaur Provincial Park, where the fossil was found. 

In addition to its particularly beautiful scenery, Dinosaur Provincial Park – located at the heart of the province of Alberta's badlands – is unmatched in terms of the number and variety of high-quality specimens.

To date, they represent more than 44 species, 34 genera and 10 families of dinosaurs, dating back 75-77 million years. This provides us with remarkable insight into life millions of years ago.

The park contains exceptional riparian habitat features as well as badlands of outstanding aesthetic value.

The creamy honey, beige and rust coloured hills around the fossil locality are outstanding examples of major geological processes and fluvial erosion patterns in semi-arid steppes — think glorious! 

The scenic badlands stretch along 26 kilometres of high quality and virtually undisturbed riparian habitat, presenting a landscape of stark but exceptional natural beauty.

The species name honours Dr. Eva Koppelhus, who has made significant contributions to vertebrate palaeontology and palynology. 

The genus is named to honour the UNESCO World Heritage Site designation for the locality where the specimen was found and from the Greek “ceratops,” which means 'horned face'. 

Dr Michael Ryan explained that he meant to honour UNESCO's efforts to increase understanding of natural history sites around the world.

UNEARTHING A JUVENILE ELASMOSAUR ON THE TRENT RIVER

In August of 2020, an incredible elasmosaur fossil—a mighty marine reptile—was unearthed high up on the cliffs of the Trent River near Courtenay, on the east coast of Vancouver Island, British Columbia. 

This thrilling find marks the culmination of a three-year palaeontological puzzle that began with mere fragments and ended with a daring cliffside excavation!

Elasmosaurs were long-necked marine reptiles roaming Earth's oceans from the Late Triassic to the Late Cretaceous (roughly 215 to 80 million years ago). 

Our Trent River specimen clocks in at about 85 million years old. The rock layers in this area were originally laid down as tropical islands far to the south of the equator. Over tens of millions of years, plate tectonics slowly carried these ancient seabeds north and slightly east to the site we know today on Vancouver Island.

For years, tantalizing fragments of this juvenile elasmosaur washed out of the riverbanks—bones that fired the imagination of fossil enthusiasts but stubbornly refused to reveal their precise origin. The first clue surfaced back in 2017 during a Courtenay Museum fossil tour led by Pat Trask. 

One lucky participant picked up a small finger bone from the river. Pat recognized it immediately as belonging to a marine reptile, possibly an elasmosaur. Although it was an exciting discovery, its source on the cliffs remained a frustrating mystery.

Fast forward to 2018. Another fossil tour, another chance encounter: a wrist bone—again, possibly elasmosaur—turning up in the Trent River. Pat looked down in that very moment and spotted a vertebra right at his feet! Now with multiple bones in hand, Pat collected them in the museum’s lab, increasingly determined to find their point of origin.

Throughout 2019, Pat and volunteers from the Vancouver Island Palaeontological Society (VIPS) combed the area for clues. They rappelled down cliff faces, deployed a drone to scour every crack and crevice, but found nothing definitive. 

Then, in August 2020, everything changed. While leading another fossil tour, Pat stumbled across a newly revealed bone in the river—one that absolutely had not been there the day before. Looking up, he spotted a promising section of cliff and, with help from his wife, Deb, and a trusty telescope, he finally spied a bone jutting from the rock.

The excavation that followed was a marvel of planning and perseverance. Scaffolding had to be built, climbing gear prepared, and countless safety measures put into place. 

Over several weeks, the team carefully pried fossil after fossil from the cliff—loose rib bones, gastroliths (stones swallowed for digestion), wrist bones, finger bones, and parts of the back and pelvis. 

The bigger prize, wrapped safely in plaster and lowered ever-so-gently to the riverbank below, contained an array of bones that could include the skull.

Pat Trask Wrapping the plaster casing

This discovery is part of the Trent River’s ongoing reputation for yielding stunning fossils. 

The Courtenay Museum regularly hosts tours here, offering members of the public a chance to walk the same banks and maybe—just maybe—spot the next big find. 

Past discoveries include other marine reptiles and invertebrate fossils, painting a picture of Vancouver Island’s prehistoric marine ecosystems.

For Pat Trask and his family, the discovery is deeply personal. Pat’s brother, Mike Trask, famously found another elasmosaur on the nearby Puntledge River back in 1988. 

There’s even talk that if this particular find proves to be a new species, it could bear the Trask family name in the scientific literature—a fitting tribute to their passion, grit, and history-making finds in the Comox Valley.

 So far, the bones point clearly to an elasmosaur. At roughly four meters in length, this juvenile is smaller than its adult kin, but it’s no less impressive. Every retrieved vertebra, humerus, and pelvis bone draws us deeper into the ancient ocean world of 85 million years ago. James Wood of the VIPS has taken on the painstaking task of preparing the specimen, aided by a new air abrasive generously provided by the Courtenay Museum.

With the fossil safely in the museum’s care, and research well underway, the Trent River elasmosaur story is poised to shine a spotlight on Vancouver Island’s extraordinary prehistoric past. From the moment that first finger bone surfaced in 2017 to the triumphant lowering of the plaster-wrapped jacket in 2020, this has been an adventure for the ages—and a spectacular reminder that our island still has secrets waiting to be discovered!

I hope to see it published with the Trask family name. Their paleontological history is forever tied to the Comox Valley and the honour would be fitting.

SECRETS IN STONE: VANCOUVER ISLAND'S TRENT RIVER

Trent River, Vancouver Island, BC

Deep in the moss-draped forests of Vancouver Island, beneath a green canopy of second-growth firs and the distant chatter of ravens, an ancient story lies written in stone. 

You’ll find it not in dusty museums but in the riverbeds, sandstone ledges, and shale cliffs of the Trent River, just south of Courtenay, British Columbia. 

This is a place where geology meets adventure — and where fossil hunters walk through time.

This area has been collected and studied in large part due to the efforts of the Vancouver Island Paleontological Society (VIPS) and its members. 

These keen and knowledgeable citizen scientists have had a huge impact on our understanding of fossils in the region. 

The picture below taken on August 20, 2020, when we were all down on the Trent for the extraction of Baby E-a marine reptile found high up in the bank by Pat Trask. 

The Courtenay Museum hosts regular fossil tours here, led by Pat Trask. On one of those field trips back in 2017, Pat was leading a trip with a family and one of the field trip participants picked up a marine reptile finger bone. 

It was laying in the river having eroded out from a nearby cliff. She showed it to Pat and he immediately recognized it as being diagnostic — it definitely belonged to a marine reptile — possibly an elasmosaur — but what species and just where on the river it had eroded from were still a mystery. As more and more of these bits and pieces were discovered, a very tasty pattern was emerging. Somewhere here, embedded in stone and eroding out bit by bit was a mighty marine reptile. 

The excavation was the culmination of a three-year paleontological puzzle of various folk finding bits and pieces of the specimen but ever elusive, had been unable to locate the source. Time and perseverance won the day and that August morning we were on hand to bring that baby, aptly named Baby-E, out of the site and off to be prepped.

In the photo are VIPS members, James Wood, Betty Franklin, Dan Bowen and Jay Hawley. Each of their personal contributions to the paleontology of the Comox Valley, Vancouver Island and the Pacific Northwest are immense.

A Journey Across Oceans and Ages

The rocks that make up the Trent River landscape weren’t born here. In fact, they began their journey over 85 million years ago, far south of the equator as part of a scattered chain of tropical islands. 

These fragments, riding the massive Pacific Plate, drifted slowly across the ocean, eventually slamming into the western edge of the North American continent.

The Pacific Plate — the largest tectonic plate on Earth, covering over 103 million square kilometers — is a restless force. Fueled by volcanic activity at its spreading center, it continues to expand, pushing against the North American Plate and forcing the ocean floor beneath the continent in a process known as subduction. Over time, this relentless collision helped build the rugged mountains and rich geological complexity of British Columbia.

Among the remnants of those far-flung islands is the Insular Superterrane — a mash-up of crustal fragments welded onto the continent from the Late Cretaceous through the Eocene. This allochthonous (meaning "foreign") terrain is geologically distinct from the rest of the mainland. The rocks you walk on along the Trent River don’t match anything next door in Alberta or even down the road. They’re relics of a world long lost to time.

Fossils Beneath Your Feet

In the 1970s, pioneering geologists Jim Monger and Charlie Ross of the Geological Survey of Canada helped map the complex tectonic puzzle of the Comox Basin. Their work revealed that by 85 million years ago, the Insular Superterrane — and the rocks of the Trent River — had already collided with the mainland, forming part of what we now know as Vancouver Island.

Back then, this region was a lush, subtropical landscape. Fossilized leaves and wood found in the area show ancient relatives of oak, poplar, maple, ash — even figs and breadfruit — thrived here. These are the botanical echoes of the Late Cretaceous, preserved in the mudstones and sandstones along the riverbank.

As you follow the river upstream, you'll come to a striking boundary: the transition from the dark-grey marine shales of the Haslam Formation to the sandy, more terrestrial Comox Formation. This contact zone marks a shift from deep ocean to coastal plain, and both formations offer their own fossil treasures.

Ammonites, Turtles, and Dinosaurs — Oh My!

Head west from Trent River Falls and you’ll arrive at Ammonite Alley, where the shale of the Haslam Formation has yielded beautiful examples of Mesopuzosia and Kitchinites, coiled marine cephalopods that once swam in warm Cretaceous seas. This section represents the Polytychoceras vancouverense ammonite zone, a biostratigraphic marker dating back roughly 84 to 83 million years.

Further along, past slick algae-covered stones and twisting alder roots, the story shifts from ocean to land. Paleontologists have uncovered both marine and terrestrial fossil turtles here — including the rare helochelydrid Naomichelys speciosa, a stubby-limbed, tank-like land turtle that once lumbered through the Cretaceous underbrush.

Even more impressive is the discovery of hadrosauroid dinosaur vertebrae by awesome possum Mike Trask — the tailbone of a duck-billed herbivore that may have wandered the nearby floodplains. Nearby, in the fine-grained sediments of Idle Creek, fossilized leaves and logs still peek from the rock, offering tantalizing clues about the forest these creatures once called home.

And then there’s the ratfish — one of the most bizarre and enigmatic finds from the Trent. Fossils of Hydrolagus colliei, a modern-day chimaera species still living off the Pacific coast, have been found in the area. This particular specimen was a bruiser, larger than its modern kin and armed with disproportionately large eyes and unusual reproductive anatomy. As unappetizing to ancient predators as it is to us, this creature is a fascinating link between ancient and modern marine ecosystems.

Where the Ancient Meets the Present

The Trent River is just one piece of a larger fossil-rich puzzle that includes nearby rivers like the Puntledge, also known for its fossil finds — including marine turtles such as Desmatochelys, as detailed in a 1992 paper by paleontologist Elizabeth Nicholls. 

The Puntledge is significant to the K'ómoks First Nation, who have lived in this region since Time Immemorial and know the river by many names from the Puntledge, Sahtloot, Sasitla, and Ieeksun.

Today, fossil hunters — amateur and professional alike — can follow the rivers through time, discovering clues to a vastly different world hidden in the layers beneath their boots.

Planning Your Adventure

If you're ready to explore the paleontological wonders of the Trent River, head about three kilometres south of Courtenay along Highway 19. Look for a safe pull-off just south of the Cumberland Interchange. A trail leads from the highway beneath the bridge, bringing you to the river’s north bank. From here, the journey unfolds — a mix of scrambling, creek-walking, and sharp-eyed searching that can reveal fossils untouched for millions of years.

To head out on a guided tour of the river, visit the Courtenay Museum website and book in with Pat Trask to take you there, share the river's paleontological history and how to find fossils.

Remember: fossil collection is regulated, so always check local rules and never remove fossils from protected sites. In British Columbia, fossils belong to the province. If you find a fossil, you become its steward, noting where you found it and keeping it safe. Sharing your fossil finds with local paleontological societies and museums helps us to know what has been found and let's you know if that find is significant. If it is a new species, it might even be named after you!

The Trent River reminds us that adventure doesn’t always mean scaling peaks or paddling rapids. Sometimes, it’s found in quiet moments along a riverside, where the moss is thick, the rocks are ancient, and time itself feels close enough to touch.

MIDDLE TRIASSIC HUMBOLT RANGE OF NEVADA

Looking out over the Middle Triassic exposures of the Humboldt Mountain Range.

I was down in Nevada to walk through the outcrops of the Humbolt Range with Dan Bowen and Betty Franklin of the Vancouver Island Paleontological Society and John Fam from the Vancouver Paleontological Society in October. 

We were kindly hosted by a wonderful fossil enthusiast who owns some prime property and agreed to drive up from California to meet us. 

These hills were the site of the 1905 Expedition of the University of California’s Department of Geology in Berkeley funded by the beautiful and bold, Annie Alexander, the women to whom the UCMP owes both its collection and existence. 

Annie brought together a paleontological crew to explore these localities and kept an expedition journal of their trip which is now on display at the University of California Museum of Paleontology at Berkeley.

Annie's interest was the ichthyosaurs and she was well pleased with the results. They dodged rattlesnakes and tarantulas, finding many new specimens as they opened up new quarries in the hills of the Humboldt Range of Nevada.

Ichthyosaurs range from quite small, just a foot or two, to well over twenty-six metres in length and resembled both modern fish and dolphins. The specimens from Nevada are especially large and well-preserved. They hail from a time, some 217 million years ago, when Nevada, and parts of the western USA, was covered by an ancient ocean that would one day become our Pacific Ocean. Many ichthyosaur specimens have come out of Nevada. So many, in fact, that they named it their State Fossil back in 1977.

Fossil fragments and complete specimens of these marine reptiles have been collected in the Blue Lias near Lyme Regis and the Black Ven Marls. More recently, specimens have been collected from the higher succession near Seatown. Paddy Howe, Lyme Regis Museum geologist, found a rather nice Ichthyosaurus breviceps skull a few years back. A landslip in 2008 unveiled some ribs poking out of the Church cliffs and a bit of digging revealed the ninth fossil skull ever found of a breviceps, with teeth and paddles to boot.

Specimens have since been found in Europe in Belgium, England, Germany, Switzerland and in Indonesia. Many tremendously well-preserved specimens come from the limestone quarries in Holzmaden, southern Germany.

BLUE LIAS ICHTHYOSAUR

This well-preserved partial ichthyosaur was found in the Blue Lias shales by Lewis Winchester-Ellis. The vertebrae you see here are from the tail section of this marine reptile.

The find includes stomach contents which tell us a little about how this particular fellow liked to dine.

As with most of his brethren, he enjoyed fish and cephalopods. Lewis found fishbone and squid tentacle hooklets in his belly. 

Oh yes, these ancient cephies had grasping hooklets on their tentacles. I'm picturing them wiggling all ominously. The hooklets were the only hard parts of the animal preserved in this case as the softer parts of this ancient calamari were fully or partially digested before this ichthyosaur met his end.

Ichthyosaurus was an extinct marine reptile first described from fossil fragments found in 1699 in Wales. Shortly thereafter, fossil vertebrae were published in 1708 from the Lower Jurassic and the first member of the order Ichthyosauria to be discovered.

To give that a bit of historical significance, this was the age of James Stuart, Jacobite hopeful to the British throne. While scientific journals of the day were publishing the first vertebrae ichthyosaur finds, he was avoiding the French fleet in the Firth of Forth off Scotland. This wasn’t Bonnie Prince Charlie, this was his Dad. Yes, that far back.

The first complete skeleton was discovered in the early 19th century by Mary Anning and her brother Joseph along the Dorset Jurassic Coast. Joseph had mistakenly, but quite reasonably, taken the find for an ancient crocodile. Mary excavated the specimen a year later and it was this and others that she found that would supply the research base others would soon publish on.

Mary's find was described by a British surgeon, Sir Everard Home, an elected Fellow of the Royal Society, in 1814. The specimen is now on display at the Natural History Museum in London bearing the name Temnodontosaurus platyodon, or “cutting-tooth lizard.”

Ichthyosaurus communis

In 1821, William Conybeare and Henry De La Beche, a friend of Mary's, published a paper describing three new species of unknown marine reptiles based on the Anning's finds.

Rev. William Buckland would go on to describe two small ichthyosaurs from the Lias of Lyme Regis, Ichthyosaurus communis and Ichthyosaurus intermedius, in 1837.

Remarkable, you'll recall that he was a theologian, geologist, palaeontologist AND Dean of Westminster. It was Buckland who published the first full account of a dinosaur in 1824, coining the name, "Megalosaurus."

The Age of Dinosaurs and Era of the Mighty Marine Reptile had begun.

Ichthyosaurs have been collected in the Blue Lias near Lyme Regis and the Black Ven Marls. More recently, specimens have been collected from the higher succession near Seatown. Paddy Howe, Lyme Regis Museum geologist, found a rather nice Ichthyosaurus breviceps skull a few years back. A landslip in 2008 unveiled some ribs poking out of the Church cliffs and a bit of digging revealed the ninth fossil skull ever found of a breviceps, with teeth and paddles to boot.

Specimens have since been found in Europe in Belgium, England, Germany, Switzerland and in Indonesia. Many tremendously well-preserved specimens come from the limestone quarries in Holzmaden, southern Germany.

Ichthyosaurs ranged from quite small, just a foot or two, to well over twenty-six metres in length and resembled both modern fish and dolphins.

Dean Lomax and Sven Sachs, both active (and delightful) vertebrate paleontologists, have described a colossal beast, Shonisaurus sikanniensis from the Upper Triassic (Norian) Pardonet Formation of northeastern British Columbia, Canada, measuring 3-3.5 meters in length. The specimen is now on display in the Royal Tyrrell Museum of Palaeontology in Alberta, Canada. It was this discovery that tipped the balance in the vote, making it British Columbia's Official Fossil. Ichthyosaurs have been found at other sites in British Columbia, on Vancouver Island and the Queen Charlotte Islands (Haida Gwaii) but Shoni tipped the ballot.

The first specimens of Shonisaurus were found in the 1990s by Peter Langham at Doniford Bay on the Somerset coast of England.

Dr. Betsy Nicholls, Rolex Laureate Vertebrate Palaeontologist from the Royal Tyrrell Museum, excavated the type specimen of Shonisaurus sikanniensis over three field sessions in one of the most ambitious fossil excavations ever ventured. Her efforts from 1999 through 2001, both in the field and lobbying back at home, paid off. Betsy published on this new species in 2004, the culmination of her life’s work and her last paper as we lost her to cancer in autumn of that year.

Roy Chapman Andrews, AMNH 1928 Expedition to the Gobi Desert

Charmingly, Betsy had a mail correspondence with Roy Chapman Andrews, former director of the American Museum of Natural History, going back to the late 1950s as she explored her potential career in palaeontology. Do you recall the AMNH’s sexy paleo photos of expeditions to the Gobi Desert in southern Mongolia in China in the early 20th century? I've posted a picture here to jog your memory. Roy Chapman Andrews was the lead on that trip. The man was dead sexy. His photos are what fueled the flames of my own interest in paleo.

We've found at least 37 specimens of Shonisaurus in Triassic outcrops of the Luning Formation in the Shoshone Mountains of Nevada, USA. The finds go back to the 1920s. The specimens that may it to publication were collected by M. Wheat and C. L. Camp in the 1950s.  The aptly named Shonisaurus popularis became the Nevada State Fossil in 1984. Our Shoni got around. Isolated remains have been found in a section of sandstone in Belluno, in the Eastern Dolomites, Veneto region of northeastern Italy. The specimens were published by Vecchia et al. in 2002.

For a time, Shonisaurus was the largest ichthyosaurus known.

Move over, Shoni, as a new marine reptile find competes with the Green Anaconda (Eunectes murinus) and the Blue Whale (Balaenoptera musculus) for size at a whopping twenty-six (26) metres.

The find is the prize of fossil collector turned co-author, Paul de la Salle, who (you guessed it) found it in the lower part of the intertidal area that outcrops strata from the latest Triassic Westbury Mudstone Formation of Lilstock on the Somerset coast. He contacted Dean Lomax and Judy Massare who became co-authors on the paper.

The find and conclusions from their paper put "dinosaur" bones from the historic Westbury Mudstone Formation of Aust Cliff, Gloucestershire, UK site into full reinterpretation.

And remember that ichthyosaur the good Reverend Buckland described back in 1837, the Ichthyosaurus communis? Dean Lomax was the first to describe a wee baby. A wee baby ichthyosaur! Awe. I know, right? He and paleontologist Nigel Larkin published this adorable first in the journal of Historical Biology in 2017.

They had teamed up previously on another first back in 2014 when they completed the reconstruction of an entire large marine reptile skull and mandible in 3-D, then graciously making it available to fellow researchers and the public. The skull and braincase in question were from an Early Jurassic, and relatively rare, Protoichthyosaurus prostaxalis. The specimen had been unearthed in Warwickshire back in the 1950s. Unlike most ichthyosaur finds of this age, it was not compressed and allowed the team to look at a 3-D specimen through the lens of computerized tomography (CT) scanning.

Another superb 3-D ichthyosaur skull was found near Lyme Regis by fossil hunter-turned-entrepreneur-local David Sole and prepped by the late David Costain. I'm rather hoping it went into a museum collection as it would be wonderful to see the specimen studied, imaged, scanned and 3-D printed for all to share. Here's hoping.

Ichthyosaurus somersetensis Credit: Dean R Lomax

Lomax and Sven Sachs also published on an embryo from one of the largest ichthyosaurs known, a new species named Ichthyosaurus somersetensis.

Their paper in the ACTA Palaeontologica Polonica from 2017, describes the third embryo known for Ichthyosaurus and the first to be positively identified to species level. The specimen was collected from Lower Jurassic strata (lower Hettangian, Blue Lias Formation) of Doniford Bay, Somerset, UK and is housed in the collection of the Niedersächsisches Landesmuseum (Lower Saxony State Museum) in Hannover, Germany.

We have learned a lot about them in the time we've been studying them. We now have thousands of specimens, some whole, some as bits and pieces. Many specimens that have been collected are only just now being studied and the tools we are using to study them are getting better and better.

BEARS: HARBINGERS OF SPRING

Stretching the legs on a Spring stroll

Some of Vancouver Island’s many bears take a stroll through the wilds in the Comox Valley. 

While stumbling upon them may cause us surprise, they have heard us (and smelled us) coming for miles. 

If you work or play in the woods of British Columbia, both grizzly and black bear sightings are common. 

As Spring arrives with warmer weather and growing daylight, bears begin awakening in the Comox Valley, across Vancouver Island and around the rest of the province, they wake up thirsty and often quench their thirst, then head back to their dens for more sleep. 

As well as parched, some have such powerful hunger they choose to forgo more sleep in favour of beginning the welcome task of searching for food. 

 

Up for a Spring snack but still a bit sleepy

They snack on plant roots, grasses, berries, insects, the shellfish on our coastlines and small mammals—all to replace the many calories they burned off over their winter hibernation. 

Nearly half the world's population, some 26,000 grizzly bears and 380,000 black bears, roam the Canadian wilderness — of those, 14,000 grizzlies and around 140,000-ish black bears call British Columbia home. 

These highly intelligent omnivores lumber along our coastlines, mountains and forests. It is hard to confirm how many live on Vancouver Island, but estimates range from 7,000 to 12,000. 

Bears in the Fossil Record Both bear families descend from a common ancestor, Ursavus, a bear-dog the size of a raccoon who lived more than 20 million years ago. Seems an implausible lineage given the size of their enormous descendants. 

Our Island black bears are a little larger than their mainland counterparts. Females can weigh up to almost 400 lbs or (180 kg), and our males get up to 600 lbs or (275 kg) in weight. 

Their beefy cousins get even bigger. An average grizzly weighs in around 800 lbs (363 kg), but a recent find in Alaska tops the charts at 1600 lbs (726 kg). This mighty beast stood 12' 6' high at the shoulder, 14' to the top of his head and is one of the largest grizzlies ever recorded — a na̱ndzi. Adult bears tend to live solo except during mating season. 

Those looking for love congregate from May to July hoping to find a mate. Through adaptation to shifting seasons, the females' reproductive system delays the implantation of fertilised eggs — blastocysts —until November or December to ensure her healthy pups arrive during hibernation. If food resources are slim, the newly formed embryo does not catch or attach to her uterine wall, and she would try again next year. 

Female grizzly bears reach mating maturity at 4-5 years of age. They give birth to a single or up to four cubs (though usually just two) in January or February. The newborn cubs are cute little nuggets — tiny, hairless, and helpless — weighing in at 2-3 kilograms or 4-8 pounds. 

They feast on their mother’s nutrient-dense milk for the first two months of life then stay with their mother for another 16 months or more. 

Once fully grown, they can run 56 km an hour, are good at climbing trees, swimming, and live 20-25 years in the wild. 

Bear encounters bring a humbling appreciation of how remarkable these massive beasts are. Knowing their level of intelligence, keen memory, and bite force of over 8,000,000 pascals — enough to crush a bowling ball — inspires awe and caution in equal measure. 

They have an indescribable presence. It is likely because of this that these majestic bears show up often in the superb carvings and work of First Nations artists. First Nation Lore and Language In the Kwak'wala language of the Kwakwaka'wakw — speakers of Kwak'wala — a grizzly bear is known as nan. 

The ornamental carved grizzly bear headdress worn by the comic Dluwalakha Grizzly Bear Dancers — Once more from Heaven — in the Grizzly Bear Dance or Gaga̱lalał, is known as na̱ng̱a̱mł. 

The Dluwalakha dancers receive supernatural treasures or dloogwi, which they pass down from generation to generation.

Should you encounter a black bear and wish to greet them in Kwak'wala, you would call them t̕ła'yi. Kwakiutl First Nations, Smoke of the World, count Grizzly Bears as an ancestor — along with Seagull, Sun and Thunderbird. To tell stories of the ancestors is na̱wiła.

Each of these ancestors took off their masks to become human and founded the many groups now bound together by language and culture as Kwakwaka’wakw. Not all Kwakwaka'wakw dance the Gaga̱lalał, but their ancestors likely attended feasts where the great bear was celebrated. To speak or tell stories of the ancestors is na̱wiła — and Grizzly bear as an ancestor is Na̱n Helus. 

Whether ancestor or neighbour, these beautiful creatures live all around us. We may see them moving through our neighbourhoods for food or returning to their habitat. 

It is vital for all of us to be mindful of how our actions impact them and to keep attractants — delicious, smelly garbage and open food — in sealed garbage cans and not outside in open containers. We share this world with them and it is our responsibility to help keep them — and us — safe.
