ANCIENT ELEGANCE: UINTACRINUS SOCIALIS

There is a particular kind of quiet magic in the world, the sort that sends a small shiver of awe through you when all the elements of deep time align. 

Every so often, nature grants us a perfect moment: minerals seep gently into ancient flesh, sediments cradle a creature’s delicate form, and the slow choreography of preservation captures a life in astonishing detail. 

For me, nothing embodies that magic quite like crinoids. These elegant echinoderms—equal parts flower and animal—feel like whispers from an ancient sea, caught forever in stone.

The specimen before us is no exception. If you lean in close and let your eyes wander across its intricate geometry, you will find yourself face to face with a stunning representative of Uintacrinus socialis. 

This Upper Cretaceous beauty, hailing from the Santonian roughly 85 million years ago, was first named nearly a century and a half ago by O.C. Marsh in honour of the Uinta Mountains of Utah. 

This specimen hail from the soft chalky layers of the Smoky Hills Niobrara Formation in central Kansas—a region that once lay beneath the warm, shallow waters of the Western Interior Seaway. Here, entire colonies of Uintacrinus drifted like living chandeliers, their feathery arms extended into the sun-dappled currents.

Crinoids are the quiet dancers of the animal kingdom. Although they appear plant-like—an underwater blossom swaying gracefully in the tide—they are very much animals, part of the illustrious echinoderm clan that includes sea stars, brittle stars, and urchins. 

Imagine a lily turned sentient: a cup-shaped central body holding a mouth on its upper surface, surrounded by delicate, branching arms that sweep food particles from the water. 

And, in true echinoderm fashion, add an anus inconveniently positioned right beside the mouth. Evolution, it seems, has a sense of humour.

The anchored species, traditionally called sea lilies, rise from the seafloor on slender stalks composed of stacked calcite rings—columnals—that resemble beads fallen from some ancient necklace. In shallower waters, the stalks can be short and sturdy, but in deeper seas they may stretch a metre or more, holding the crinoid aloft like the mast of a living ship, swaying gently with each passing current.

Yet most crinoids in today’s oceans are not anchored at all. The feather stars, or comatulids, break free from their juvenile stalks and spend their adulthood drifting, crawling, or even swimming with slow, balletic strokes of their arms. 

They cling to rocks and coral with tiny curved structures called cirri—delicate as eyelashes yet strong enough to grip firmly in swirling water. These cirri also allowed many fossil crinoids to hold fast to the Cretaceous seafloor, weathering tides and storms in the vast expanse of the Western Interior Seaway.

Like all echinoderms, crinoids exhibit pentaradial symmetry: a five-fold architecture expressed in their plates, arms, and feeding grooves. The aboral, or underside, of the calyx is encased in a mosaic of calcium carbonate plates that form their internal skeleton—robust enough to fossilize beautifully. 

The top surface, the oral area, is mostly soft tissue in life, opening into five deep ambulacral grooves where tube feet once reached outward like tiny graceful fingers. Between these lie the interambulacral zones, together forming the elegant star-like pattern that both living and fossil crinoids display.

Their fossil record is ancient and abundant. Crinoids first appear in the Ordovician over 450 million years ago—unless one counts Echmatocrinus, that strange and controversial form from the Burgess Shale whose affinities still spark debate among paleontologists. 

Through the Paleozoic, crinoids flourished in such numbers that their disarticulated columnals often blanket limestone beds. In some places, these columnals form the very fabric of the rock itself, creating entire cliffs built from the remnants of ancient underwater meadows. To run your fingers along such a rock is to touch a community that lived hundreds of millions of years before humans ever drew breath.

And yet, crinoids endure. They survive today in tropical reefs, deep ocean slopes, and soft-bottomed basins, their lineage stretching unbroken from those early Paleozoic seas to the modern oceans. 

Some cling to the seafloor in twilight depths; others drift like feathered ghosts, arms unfurling in silent, rhythmic pulses. 

When a fossil like Uintacrinus socialis emerges from the chalk of Kansas or the limestone of Utah, we are granted a rare window into that vanished age. 

And for those of us who spend our days searching riverbeds, quarries, and sea cliffs for such wonders, as I am sure you do, it is for the thrill of having a satisfying split and letting the past shine through.

That, to me, is pure magic.

CHEERFUL CHICKADEES: WASHINTON'S TINY WINTER SONGBIRD

On a frosty Washington morning, when mist clings to the Douglas firs and frost paints the ferns silver, a flit of motion catches your eye—a small, round bird with a bold black cap and curious, sparkling eyes. 

It lands on a branch covered in ice crystals, flicks its tail, and calls out its name: chick-a-dee-dee-dee! 

Few sounds are as heartening in the Northwest woods as the song of the chickadee, a reminder that even in the quiet cold of winter, life hums along in cheerful defiance.

Chickadees are some of the most beloved birds in Washington State. Two species are especially common: the Black-capped Chickadee (Poecile atricapillus), found in lowland forests, parks, and backyards, and the Chestnut-backed Chickadee (Poecile rufescens), a fluffier cousin that prefers the damp coniferous forests of the coast and Cascades. Both species are year-round residents—tiny nonmigratory survivors who somehow endure the state’s wet winters and brief, brilliant summers.

Despite weighing less than a dozen paperclips, chickadees are bold, curious, and surprisingly fearless. Birdwatchers often find them among the first to visit feeders, snatching a seed and darting off to store it for later. They can remember the locations of hundreds, even thousands, of hidden food caches—an astonishing feat of memory for such a small creature.

Their name, “chickadee,” comes from their signature call, which varies in tone and number of “dees” depending on what’s happening. A few soft notes mean “all is well,” while a flurry of dee-dee-dees can signal alarm. The more “dees,” the greater the threat—almost like a feathery Morse code. Researchers have discovered that chickadees use an intricate communication system that rivals those of parrots or crows in complexity.

Chickadees thrive in Washington because of their incredible adaptability. They’re found from the Olympic Peninsula’s moss-draped rainforests to the dry ponderosa pine country east of the Cascades. In winter, they fluff their feathers to trap heat and can even lower their body temperature at night to conserve energy—a form of regulated hypothermia called torpor.

They feed on insects, seeds, and berries, often gleaning tiny larvae from bark crevices or pecking open fir cones for seeds. In summer, they shift toward a high-protein diet of caterpillars and spiders, feeding their chicks a steady stream of wriggling meals.

Each spring, chickadees begin their courtship with soft calls and playful chases through the trees. They’re cavity nesters, meaning they prefer to raise their young in holes—often old woodpecker nests or natural tree cavities. Sometimes they’ll even excavate a soft-rotted snag themselves, a remarkable feat for such a small bird.

Once a site is chosen, the female lines the nest with moss, fur, and feathers, creating a cozy chamber for her eggs. Typically, she lays 6–8 small white eggs, which she incubates for about two weeks. Both parents take part in feeding the chicks, bringing in insects almost constantly until the young fledge and venture into the world.

In Washington, chickadees are more than just a common backyard bird—they’re a symbol of resilience and cheer. Their constant movement and lively chatter seem to bring warmth even to the dampest winter days. Many Washingtonians hang feeders of black oil sunflower seeds or suet to attract these tiny visitors, rewarding them with a flurry of acrobatics and music.

If you’re out hiking in Mount Rainier National Park or walking through Seattle’s Green Lake Park, listen for that bright, whistled fee-bee or the classic chick-a-dee-dee-dee. You may find a black-capped chickadee tilting its head curiously at you from a low branch, unbothered by your presence.

Chickadees, like all modern songbirds, trace their lineage deep into the fossil record—back to the Miocene, around 23 to 5 million years ago, when the ancestors of the family Paridae (which includes chickadees, titmice, and tits) first appeared in Europe and Asia. 

These early perching birds evolved from small, insect-eating passerines that diversified rapidly after the extinction of the dinosaurs, filling the forests of the world with song. Fossil evidence from sites in Europe, such as the famed Miocene deposits of Germany, shows small tit-like birds already possessing the short, stout bills and agile feet that characterize today’s chickadees. 

Over time, these adaptable birds spread across the Northern Hemisphere, eventually colonizing North America through Beringia during cooler Pleistocene glacial periods. The Washington State chickadees we see today—bold, intelligent, and winter-hardy—carry within them the ancient legacy of these pioneering songbirds that once flitted through prehistoric forests millions of years ago.

In the heart of Washington’s wild landscapes—beneath towering cedars, beside mountain streams, or even outside your kitchen window—the chickadee sings. Unfazed by rain or snow, this tiny bird embodies the wild spirit of the Pacific Northwest: curious, enduring, and always full of life.

ANCIENT AMBUSH KILLER: MACHAIRODUS

Saber-Toothed Cat, Machairodus aphanistus

The skull before you lies cradled in a glass case at the Museo Nacional de Ciencias Naturales in Madrid, Spain.

This museum—one of my most cherished anywhere in the world—houses extraordinary treasures in the heart of a city I adore.

Even at a distance, the skull seems almost unreal, its sweeping lines and lethal symmetry more like an artifact of myth than a product of natural selection.

The upper canines of Machairodus aphanistus sweep downward in a deadly curve, their bases thick and reinforced, their blades tapering into elegant, murderous crescents. 

Grooves along their sides lighten the teeth without robbing them of strength, an evolutionary compromise that allowed this ancient predator to deliver precise, slicing blows. The zygomatic arches flare outward with commanding confidence, a testament to the enormous jaw muscles that once powered the bite. Even the wide nasal opening hints at a creature ruled by scent, finely attuned to the faintest whispers of prey on a warm Miocene wind.

This skull—stripped of flesh, muscle, and fur—remains a vivid record of a predator that walked the Earth between nine and five million years ago, long before the saber-toothed icons of the Americas made their mark. 

Machairodus aphanistus lived in the shifting landscapes of the Late Miocene, a time when Europe and western Asia were giving way to broader grasslands and open woodlands. Forest canopies receded. Herds grew larger and faster. Predators had to adapt or perish, and Machairodus responded with a design both beautiful and deadly.

Unlike its more famous descendant, Smilodon, with its compact body and powerful forelimbs, Machairodus moved with the grace of a panther. It was long-limbed and athletic, relying on bursts of speed and stealth to launch an ambush. But its skull tells a more nuanced story—one of tension between speed and specialization. The tall sagittal crest reveals a powerhouse of jaw muscles anchoring deep into the bone. 

The forward-facing orbits provide the stereoscopic vision needed to track prey with extraordinary accuracy. The sheer length of the canines required a jaw capable of opening nearly ninety degrees, a gape far wider than that of any modern cat, allowing those great blades to descend unobstructed into vulnerable regions like the throat.

You will be relieved to hear that our ancestors did not hunt and were not hunted by this impressive predator. Machairodus aphanistus went extinct in the Late Miocene, roughly 5–9 million years ago.

The earliest members of the human lineage (Homo) did not appear until about 2.8 million years ago, in the early Pleistocene. Even our more ancient relatives—Australopithecines—don’t show up until 4–4.5 million years ago.

So there is a gap of millions of years between the disappearance of Machairodus and the emergence of anything that could be considered human or human-adjacent. For that, I think we can all breath a collective sigh.

Still, others were alive on the plains that were their hunting grounds. Both hunters and prey.

In the warm, open savannas of the Miocene, the world of Machairodus was alive with competition. Packs of early hyenas honed their bone-crushing skills. Bear-dogs patrolled the river valleys. Other machairodonts—kin, rivals, or both—shared the same hunting grounds. 

The herbivores were just as diverse: early horses galloped across the plains in tight herds, while rhinocerotids, camelids, and horned antelope moved in cautious groups, ever aware of shadows that shifted in the tall grass. To survive in this dynamic ecosystem, Machairodus embraced an ambush strategy refined over countless generations. It would stalk silently, using shrubs, boulders, or dim forest edges for cover. 

When the distance closed, it lunged with explosive force, using its muscular forelimbs to pin or destabilize its prey before delivering a swift, slicing bite to the neck. Death came quickly—less by crushing force and more by catastrophic blood loss.

There is a sense, looking at its skull that you are seeing an evolutionary idea mid-transformation.

Machairodus aphanistus stands at a pivotal moment in the story of the saber-toothed cats. Its body remained agile and panther-like, but its cranial features were edging ever closer to the extreme adaptations that would define later giants like Homotherium and Smilodon. It represents a crucial chapter in which nature was experimenting, refining, and pushing the boundaries of what a predator could become.

The skull contains all of this history within its bone: the open grasslands, the pounding hooves of prey, the quiet tension of ambush, and the relentless arms race that shaped predator and prey alike. 

In its silence, it speaks. It tells of a world both familiar and wild, a world where the line between beauty and brutality was sharpened to a sabre’s edge.

ICELAND'S BLACK SAND BEACH

Reynisfjara, Iceland's Black Sand Beach

Imagine a beach covered with impossibly smooth black stones. In site of the shore, stand tall black basalt sentinels and a cliff of basalt behind you. 

This dreamlike setting is Iceland’s famed black-sand shores. Wind, rain, puffins and surf—a bucket-list moment. 

The beach—Reynisfjara, a wind-scoured sweep on the island’s southern edge—unfurls beneath a sky bruised with storm light and salted mist. 

Each wave rushes in with a roar that rolls through your ribs. When the water drains back, it draws away over sand so dark it behaves like a mirror, reflecting the cloud-washed sky in long silver ribbons.

Iceland sits astride the Mid-Atlantic Ridge, a tectonic boundary where the North American and Eurasian plates pull apart at a geological snail’s pace—an inch or two each year. 

Rising beneath this rift is a mantle plume, a column of hot rock that feeds Iceland’s remarkable volcanism. Eruptions here are not rare; they are a defining rhythm of life.

When lava from the island’s volcanoes meets the frigid North Atlantic, it shatters almost instantly. 

Sea Stacks, Reynisfjara, Iceland

Thermal shock fractures the molten rock into fine, glassy fragments—tiny shards of basalt, magnetite-rich minerals, and volcanic glass called tachylite. 

Over centuries, these microscopic pieces are tumbled smooth by tide and storm, accumulating into endless black expanses that gleam like obsidian under low Arctic sun.

Just above the surf line rises a natural marvel so striking it feels engineered: a vast wall of columnar basalt, known as Hálsanefshellir. 

At first glance it looks like an organ pipe gallery fit for a storm god. In truth, it is the architecture of cooling lava. Even with the inclement weather, it was being fully explored by waves of tourists. 

When a thick basaltic flow slowly cools, it contracts and fractures along geometric planes. The result is a forest of hexagonal pillars—mathematical, precise, and impossibly ordered for something born of chaos. 

The Cave at Reynisfjara, Iceland

These columns stack and curve like ribs along the cliff face, forming a cavern whose acoustics mimic a cathedral. 

The cave, carved by relentless Atlantic weathering, feels ancient yet alive. Each winter storm pries loose boulders from the upper wall; each summer’s calm polishes the stones below.

The sound inside the cave is a chorus: wind whistling through basalt corridors, waves booming like drums, and the occasional cry of seabirds nesting along the ledges. 

Even the light behaves differently here—broken and refracted into soft geometric shadows.

Offshore stand Reynisdrangar, three jagged sea stacks rising like dark sentinels from the foam. I risked getting close to them to feel the incredible power of the surf, but also kept an eye on it as I had arrived on a rising tide.

The scene was moody and dreamlike. The silhouettes shift with the tide and light—sometimes harsh and angular, sometimes softened into mythic silhouettes. Legend says they were once trolls turned to stone by the rising sun. Geology tells a different story.

Reynisdrangar are the remnants of an ancient volcanic plug—stubborn harder rock that resisted erosion long after surrounding cliffs surrendered to the sea. As waves undercut the basalt headland, fractures widened into arches, arches collapsed into towers, and the towers now endure as lonely paragons of erosion’s slow sculpting hand.

Their basalt cores are layered with volcanic ash and pillow lavas, hinting at a prehistoric eruption beneath ice or water. 

Seabirds—guillemots, kittiwakes, and Atlantic puffins—wheel around them in summer, decorating their cliffs with life and movement. I was sad to miss the puffins, but I will return to these shores again in the Spring. 

Reynisfjara is beautiful, but it is also powerful—and unpredictable. Sneaker waves, born from distant storms off Antarctica, surge higher than expected, racing up the sand with startling speed. 

They are a reminder that this coast is shaped by forces vast and ongoing: plate tectonics, glacial history, volcanic fire, and a restless ocean with no memory of the day before.

This is Iceland at its most iconic: stark, sculptural, and alive. It delivered all the feels I was looking for. It also delivered some wonderful palm-sized souvenirs that were inspected with interest as I moved through Customs on the way home.

URSUS CURIOUS: TLA'YI

A young Black Bear cub, Ursus americanus, tip-toes toward a frisky (and very startled) Striped Skunk, Mephitis mephitis — two wonderfully charismatic neighbours here in southern British Columbia.

Skunks, despite their reputation as the great olfactory villains of the mammal world, are actually closer to Old World stink badgers than to true polecats. 

Their infamous spray comes from paired anal scent glands capable of delivering a sulphur-rich chemical cocktail with uncanny accuracy — up to three metres, cross-wind. 

A single blast contains thiols so potent that predators learn, very quickly, that curiosity is overrated. Well… most predators. This wee bear clearly didn’t get the memo.

Black Bear cubs are, by nature, little bundles of kinetic joy and overwhelming inquisitiveness. Born in mid-winter, blind and tiny (weighing little more than a can of soup), they spend their first months cozied up in the den. 

By spring, though? Trouble. Pure, adorable trouble. Cubs stay with their mothers for about two years, learning every essential skill — how to climb, what to eat, what not to poke — but sometimes a particularly irresistible mystery will lure one a few metres away for a solo investigation.

Skunks, meanwhile, are far more than their signature scent. They’re accomplished insectivores with surprisingly strong forelimbs, adapted for rooting out beetle larvae, grubs, and other soil-dwelling goodies. 

They’re also bold. A skunk will usually stomp its feet, click its teeth, and arch its tail in a dramatic “Don’t make me do it” warning display. 

And yet — miracle of miracles — nobody got skunked. A karmic win for everyone involved.

This charming moment is also a reminder of the rich biodiversity we’re blessed with on the rugged west coast of British Columbia, where coastal rainforests shelter everything from salmon-loving black bears to nocturnal, grub-snuffling skunks.

Bears and skunks also have deep, fascinating roots in the fossil record. The lineage leading to modern skunks (Mephitidae) first appears in the Oligocene, roughly 30–32 million years ago, with early forms like Promephitis showing many of the skeletal hallmarks — and likely the scent-gland superpowers — of their modern cousins. 

Bears (Ursidae), meanwhile, trace their ancestry back even further. Their earliest known relatives emerge in the late Eocene, around 38 million years ago, with small, doglike proto-bears such as Parictis and later the hemicyonids, sometimes called “dog-bears,” bridging the evolutionary steps toward the true bears we know today. 

By the Miocene, both families were well established across North America, sharing ancient forests and floodplains just as their modern descendants do today — though hopefully with just as few skunk-related mishaps.

In the Kwak'wala language of the Kwakwaka'wakw First Nations of the Pacific Northwest, this playful black bear is t̕ła'yi — a name that captures both its spirit and its place within these lands. 

A perfect word for a perfect little explorer with an arguably questionable sense of danger.

HOLCOPHYLLOCERAS: A JEWEL OF JURASSIC SEAS

What is most wonderful about natural science is that every fossil—every spiral, ridge, and suture—opens a window onto a vanished world. 

Take, for instance, this tremendously robust, intricately sutured ammonite: Holcophylloceras mediterraneum (Neumayr, 1871). Collected from Late Jurassic (Oxfordian) deposits near Sokoja, Madagascar, it is a marvel of paleontological sculpture, a testament to evolutionary experimentation that thrived in the tropical Tethyan seas some 160 million years ago.

Madagascar has long been recognized as a treasure trove of beautifully preserved fossils. From its Cretaceous dinosaurs to its Triassic amphibians and its extraordinary Jurassic ammonites, the island offers a richness few regions can rival. 

The spiraled shell of Holcophylloceras mediterraneum is no exception—its ornate sutures and lustrous preservation hint at a creature exquisitely adapted to the warm, shallow continental shelf of Gondwana’s eastern margin.

Like all ammonites, Holcophylloceras built its shell in a series of chambers divided by walls known as septa. These septa, when intersecting the outer shell, formed the elaborate suture patterns that make collectors swoon—tangled, fractal-like lines that resemble botanical tracings or rivers on an ancient map.

Running through each chamber was the siphuncle, a biological marvel that allowed the ammonite to adjust the gas and fluid content inside its shell. In effect, ammonites carried a set of built-in ballast tanks, enabling them to rise and sink through the water column almost effortlessly. Their final and largest chamber—the body chamber—housed the soft tissues, including the tentacles, eyes, and muscular arms.

Picture, if you will, a squid or octopus, then surround it with a coiled, beautifully ribbed shell. Now place it in a warm tropical sea filled with predators and prey, reefs and drifting plankton, and a ton upon ton of water pressing down from above. That was the world Holcophylloceras mastered.

The Oxfordian oceans surrounding Madagascar were not quiet waters. They were alive—thrumming with movement, colour, and competition. The ammonite’s elegant spiral belies the reality of its bustling neighbourhood. Some of the many animals that would have swum, crawled, hunted, or drifted around Holcophylloceras mediterraneum include:

Marine Reptiles

• Plesiosaurs – long-necked Cryptoclidus–like forms gliding between shoals of fish.
• Ichthyosaurs – such as Ophthalmosaurus, sleek torpedo-shaped hunters with dinner-plate eyes built for dim, deeper waters.
• Pliosaurs – apex predators like Liopleurodon, whose cavernous jaws could swallow a human whole.

Other Cephalopods

Belemnites – dart-shaped squid-relatives such as Hibolithes, flickering through the water column like living arrows.

Other ammonite genera sharing these seas:

• Perisphinctes
• Asaphoceras
• Physodoceras
• Aspidoceras
• Glochiceras

Each species filled its own ecological niche, from fast-swimming pursuit hunters to slow-drifting plankton feeders.

Fishes and Sharks

• Hybodont sharks – including Hybodus and Asteracanthus, equipped with crushing teeth for shelled prey and formidable dorsal spines.
• Teleost fishes – early ray-finned fishes beginning to diversify.
• Coelacanths – ancient lobe-finned holdovers patrolling calmer waters.

Invertebrates

• Bivalves – oysters, rudists, and inoceramids carpeting the shallow seafloor.
• Gastropods – from turreted turritellids to broad-shelled neritids.
• Crustaceans – shrimp, lobsters, and small crabs scraping algae from reef structures.
• Sea urchins and echinoids – spiny architects of sandy burrows.

Reefs & Drifting Life

• Sponges and corals creating pocket reefs in warm carbonate-rich environments.
• Planktonic foraminifera and radiolarians – the drifting micro-architecture of the Jurassic sea, powering food webs from below.

Ammonites like Holcophylloceras thrived in these diverse ecosystems by filling a mid-level trophic niche. They were both predator and prey—nimble enough to hunt small fish and crustaceans, yet vulnerable to larger hunters. Their greatest evolutionary advantage was their ability to regulate buoyancy, adjusting depth as easily as a modern submarine.

But their most beautiful legacy remains their shells. In death, they fell to the seafloor, where their chambers filled with sediment, minerals, and eventually time itself. 

Today, polished by erosion or revealed in limestone, they offer a perfect blend of geometry, biology, and ancient artistry.

MASSIVE ICHTHYOSAUR VERTEBRAE FROM NEVADA

The massive marine reptile vertebra you see here—broad, five-sided, drum-shaped, and heavy enough to require two hands to lift—once belonged to an ichthyosaur, one of the most impressive lineages of marine reptiles ever to patrol Earth’s oceans. 

This particular fossil hails from Berlin–Ichthyosaur State Park in central Nevada, a high desert landscape where sagebrush now whispers over ground that was once submerged beneath a warm, tropical Triassic sea.

During the Late Triassic, roughly 217 million years ago, this region lay along the western margin of the supercontinent Pangaea. 

Shallow, nutrient-rich waters supported a thriving marine ecosystem dominated by ammonites, early fish, and  ichthyosaurs.

Today, the Berlin–Ichthyosaur site is the richest concentration of large ichthyosaur fossils in North America. 

More than 37 articulated or semi-articulated skeletons have been excavated from the Luning Formation, a thick sequence of limestone and shaly carbonates that records the rise and fall of this ancient seaway. 

These rocks formed from fine carbonate mud and shell debris that settled on the sea floor, gradually entombing the bodies of these marine giants under quiet, low-oxygen conditions ideal for fossil preservation.

The site’s fossil beds preserve something even more scientifically tantalizing: multiple large individuals clustered together in a single stratigraphic horizon. 

Whether these accumulations represent mass strandings, predator trap dynamics, toxic algal events, or a natural death assemblage remains debated.

What you don’t see in the photo are the enormous grins we’re both wearing as we marvel over this beauty—hers because she gets to hold it, and mine because I get to capture the moment. 

Thank you, Berlin-Ichthyosaur!

WHEN GORGONS REIGNED SUPREME

Step back into the deep Paleozoic—an era that began some 540 million years ago with oceans bustling with trilobites, early fish, and soft-bodied wonders, while the continents themselves hosted little more than humble mats of mosses and fungi. Life’s great drama was still mostly underwater.

Fast-forward 240 million years, and the evolutionary landscape had transformed dramatically. 

Vertebrates had conquered the land, ecosystems had diversified, and Earth’s surface teemed with reptilian innovators, amphibians the size of crocodiles, and the early ancestors of mammals. Among these emerging terrestrial titans strode the Gorgonopsians, or “Gorgons”—ferocious sabre-toothed therapsids that dominated the Middle to Late Permian, from about 265 to 252 million years ago.

These were no sluggish proto-reptiles. Gorgons were highly specialized predators, boasting elongated canine teeth worthy of any future saber-toothed cat, powerful jaws, and sleek, muscular bodies built for pursuit. Their anatomy blended the primitive and the prophetic: reptile-like postures paired with early mammalian traits such as differentiated teeth and strong jaw musculature. 

Their clawed limbs, keen forward-facing eyes, and cutting-edge predatory adaptations placed them firmly at the top of the Permian food chain. In a world long before dinosaurs, they were the undisputed apex hunters.

My own fascination with these remarkable creatures was ignited by Gorgons, Peter Ward’s wonderfully wry and insightful dive into the ancient landscapes of South Africa. Ward’s vivid tales of fieldwork in the blistering, bone-dry vastness of the Karoo Basin—ancestral home of the Gorgons—captured both the hardships and the sheer exhilaration of unearthing deep time. 

His descriptions of sunburn and scientific revelations in that arid world made me laugh more than once. It is a highly enjoyable read.

The Great Karoo itself is a geological and paleontological marvel. This enormous, semi-arid expanse formed within a vast inland basin roughly 320 million years ago, at a time when the part of Gondwana destined to become Africa lay draped across the South Pole. 

Layer upon layer of sedimentary rock accumulated as glaciers advanced and retreated, rivers meandered, lakes dried, and ecosystems rose and fell. Today, those layers read like a grand evolutionary chronicle, preserving a world populated by beaked herbivores, hulking amphibians, and the charismatic, toothy Gorgonopsians.

This was a pivotal chapter in Earth’s history—just before the catastrophic Permian-Triassic extinction swept away nearly 90% of life. Yet in the twilight of the Permian, before that great dying, the Karoo thrived with innovation and ecological complexity. It was a world where the early steps toward warm-bloodedness were being taken, where synapsids (our own deep ancestors) were experimenting with new forms, and where the Gorgons reigned supreme.

SEMENOVITES OF THE CASPIAN RIM: CRETACEOUS AMMONITES OF KAZAKHSTAN

This tasty block of Semenovites (Anahoplites) cf. michalskii hails from Cretaceous, Albian deposits that outcrop on the Tupqaraghan — Mangyshlak Peninsula, a stark and beautiful finger of land jutting into the eastern Caspian Sea in western Kazakhstan. 

The ammonites you see here are housed in the collection of the deeply awesome Emil Black. 

Their ancient provenance lies in rocks laid down some 105–110 million years ago, a time when warm epeiric seas flooded much of Central Asia and the ancestors of these coiled cephalopods thrived in shelf environments rich in plankton and marine life.

Present-day Kazakhstan is itself a geological palimpsest, a place made from multiple micro-continental blocks that were rifted apart during the Cambrian, later sutured back together, then pressed against the southern margin of Siberia before drifting to where we find them today. 

The Mangyshlak block preserves a record of these shifting tectonic identities, its plateaus and scarps reading like the torn edges of continents long departed.

The Mangyshlak (Mangghyshlaq) Peninsula is a land of structure and emptiness—high, wind-planed plateaus abruptly broken by escarpments, dry valleys, and shallow basins bleached white with salt. 

To the west lies the Caspian Sea; to the northeast the marshy Buzachi Peninsula, its wet depressions feeding migratory birds and a surprising profusion of reeds. Just north, the Tyuleniy Archipelago—a scattering of low islands—hints at the shallow bathymetry and shifting sediment loads that dominate this coastline.

Field workers on Mangyshlak often describe the region by its broad horizontality. The sky feels enormous, unbroken, a pale arch stretching over the tawny plateaus. The ground underfoot is firm but dusty, composed of compacted sandy limestones and weathered marl that break into familiar, fossil-bearing blocks. The climate is dry, the winds persistent, and visibility often perfect—ideal for spotting promising outcrops from a great distance.

Kazakhstan as a whole is a nation shaped by contrasts. Lowlands form fully one-third of its landmass. Hilly plateaus and plains account for nearly half. Low mountainous regions rise across the eastern and southern margins, making up roughly one-fifth of the terrain.

This spacious geography culminates at Mount Khan-Tengri (22,949 ft / 6,995 m) in the Tien Shan range, a crystalline sentinel marking the border between Kazakhstan, Kyrgyzstan, and China. These far-off mountains are invisible from Mangyshlak, but their presence is felt in the broad regional tectonic architecture.

 
The Western Lowlands and the Caspian Depression

The Tupqaraghan Peninsula lies within the influence of the Caspian Depression, one of the lowest terrestrial points on Earth. At its deepest, the Depression reaches 95 feet below modern sea level, a phenomenon caused by both tectonic subsidence and the unusual hydrology of the endorheic Caspian Basin.

To the south, the land rises gradually into the Ustyurt Plateau, an immense chalk and limestone table marked by wind-sculpted buttes and long, eroded escarpments. The Tupqaraghan Peninsula itself is cut from these same sedimentary sequences—Miocene, Paleogene, and Mesozoic strata cropping out in irregular terraces that lure geologists and paleontologists alike.

This is a region where erosional processes are laid bare. Minimal vegetation allows exposures to remain clean and highly visible; many slopes are studded with ammonites, inoceramid bivalves, belemnite rostra, and the fragmentary remains of marine reptiles and pterosaurs. Expeditions here frequently report layers rich in small, well-preserved invertebrate fossils, their delicate sutures and ornamentation astonishingly intact.

 
Deserts, Uplands, and Salt-Lake Basins

Much of Kazakhstan is dominated by arid and semi-arid environments, and the Mangyshlak Peninsula is no exception. To the east and southeast of the region lie the great sand deserts that define Central Asia:

• Greater Barsuki Desert
• Aral Karakum Desert
• Betpaqdala Desert
• Muyunkum and Kyzylkum Deserts

These swaths of wind-polished grains advance and retreat across broad flats and shallow depressions. The vegetation here—shrubs, saxaul, and salt-tolerant herbs—is sparse, drawing life from subterranean groundwater or ephemeral spring melt.

In central Kazakhstan, salt-lake depressions punctuate the uplands. These basins often shimmer under the sun, their surfaces coated in chalky halite crusts that record cycles of evaporation stretching back millennia.

To the north and east the land lifts again, rising into ridges and massifs: the Ulutau Mountains, the Chingiz-Tau Range, and the Altai complex, which sends three great ridges reaching into Kazakhstan. Farther south, the Tarbagatay Range and the Dzungarian Alatau introduce still more rugged topography before the landscape resolves again into plains around Lake Balkhash.
Paleontological Richness of the Region

Kazakhstan is famed for more than its ammonites. Dinosaurian bones, trackways, and scattered pterosaur remains punctuate Mesozoic and Paleogene localities across the nation. The Mangyshlak region in particular has yielded:

• Albian ammonites
• Cretaceous bivalves
• Marine reptile fragments
• Occasional vertebrate traces

These Semenovites come from a fossiliferous belt once submerged under a warm, shallow sea—a world unfurled in silt and light where these cephalopods thrived.

HAIDA GWAII: MISTY SHORES AND DAPPLED LIGHT

Misty shores, moss-covered forests, dappled light, and the smell of salt air—these are my memories of Haida Gwaii, a land where ancient stories are written in stone.

Formerly known as the Queen Charlotte Islands, the archipelago of Haida Gwaii lies at the far western edge of Canada, where the Pacific Ocean meets the continental shelf. 

These islands—steeped in the rich culture of the Haida Nation—are not only a cultural treasure but a geologic and paleontological wonderland.

Geologically, Haida Gwaii is part of Wrangellia, an exotic tectonostratigraphic terrane that also includes parts of Vancouver Island, western British Columbia, and Alaska. The region's complex geological history spans hundreds of millions of years and includes volcanic arcs, seafloor spreading, and the accretion of entire landmasses.

The Geological Survey of Canada (GSC) has long been fascinated with these remote islands. 

Their geologists and paleontologists have led numerous expeditions over the past century, documenting the diverse sedimentary formations and fossiliferous beds. 

Much of the foundation for this work was laid by Joseph Frederick Whiteaves, the GSC’s chief paleontologist in Ottawa during the late 19th century.

In 1876, Whiteaves published a pioneering paper on the Jurassic and Cretaceous faunas of Skidegate Inlet. This work firmly established the paleontological significance of the archipelago and cemented Whiteaves’ reputation as a global authority in the field. His paper, "On the Fossils of the Cretaceous Rocks of British Columbia" (GSC Report of Progress for 1876–77), remains a key early reference for West Coast palaeontology.

Later, Whiteaves would go on to describe Anomalocaris canadensis from the Burgess Shale—an “unlike other shrimp” fossil that would later be recognized as one of the most extraordinary creatures of the Cambrian explosion.

Whiteaves' early work on the fossil faunas of Haida Gwaii, particularly in the Haida Formation, created a foundation for generations of researchers to follow.

One of our most memorable fossil field trips was to the Cretaceous exposures of Lina Island, part of the Haida Formation. We considered it one of our “trips of a lifetime.” 

With great sandstone beach exposures and fossil-rich outcrops dating from the Albian to Cenomanian, Lina Island offered both scientific riches and stunning natural beauty.

Haida Fossil Fauna

Our expedition was supported and organized by John Fam, Vice Chair of the Vancouver Paleontological Society, and Dan Bowen, Chair of the British Columbia Paleontological Alliance and the Vancouver Island Paleontological Society. 

Their dedication to fostering collaborative research and building relationships with local Haida communities was key. 

We were warmly welcomed, and field trips to fossil sites were arranged in partnership with community members and cultural stewards.

The Haida Formation yielded beautifully preserved specimens embedded both in bedding planes and in concretions—hard, rounded nodules that often house exceptionally preserved fossils. 

Collecting in the mists along the foreshore, our finds included:

• Douvilleiceras spiniferum
• Brewericeras hulenense
• Cleoniceras perezianum
• Fossil cycads, evidence of rich Cretaceous plant life

These fossils offered a rare glimpse into an ancient marine ecosystem that once teemed with life. Douvilleiceras, a spiny ammonite, is particularly striking. 

Douvilleiceras spiniferum, Haida Gwaii

This genus, first identified by Whiteaves from Haida Gwaii, ranges from the Middle to Late Cretaceous and has been found across Asia, Africa, Europe, and the Americas.  

The Haida specimens, from the early to mid-Albian, to my eye are the most beautiful—and beautifully preserved.

  Douvilleiceras is one of my favourite ammonites of all time and I was blessed to find several good examples of that species from our expeditions to these fossil-rich outcrops.

All of the fossils I collected from Haida Gwaii have been skillfully prepped and donated to the Haida Gwaii Museum in Skidegate, British Columbia. 

It is a privilege to contribute in a small way to the scientific and cultural understanding of these extraordinary islands.

MOSASAURS: LORDS OF OUR CRETACEOUS SEAS

A Mosasaur Snatches a Tasty Bite

Slip beneath the surface of a Late Cretaceous ocean—if you dare—and you enter the domain of one of Earth’s most spectacular marine predators: the mosasaur. 

Long before whales ruled the deep, these muscular, paddle-limbed lizards patrolled warm inland seas with the confidence of creatures that knew nothing could challenge them for long.

Imagine a body built like a torpedo, jaws hinged like a trap, and teeth designed for the dual purposes of slicing and holding. Some species stretched over 15 metres long—longer than a city bus—yet they moved with the agility of oversized crocodiles on turbo mode. 

With a powerful tail fin beating side to side, they could lunge forward in explosive bursts, swallowing ammonites whole or ambushing unsuspecting sharks. Yes—sharks were on their menu.

Scientifically, mosasaurs are a wonderful paradox. They were reptiles—close cousins of modern monitor lizards—but they evolved flippers, streamlined skulls, and even tail flukes remarkably similar to those of whales and ichthyosaurs. Convergent evolution at its flashy finest.

Mosasaurs hunted in our Cretaceous Seas

Their fossils also tell a tale of planetary drama. The chalky cliffs of Europe, the badlands of Morocco, the ancient seaways of Kansas—all hold the remains of these sea dragons. 

Every jawbone and vertebra is a relic from a vanished ocean that once split North America in two.

Along the rugged shores of Vancouver Island, mosasaurs left their mark as well. 

In the Nanaimo Group—marine deposits laid down in the twilight of the Cretaceous—researchers have uncovered beautifully preserved remains that once cruised the ancient Pacific coastline. 

Species recorded from these rocks include Tylosaurus pembinensis, Plioplatecarpus marshii, Mosasaurus hoffmanni, Clidastes liodontus, and the smaller but no less impressive Phosphorosaurus ponpetelegans. 

These fossils, often found in shale and sandstone, offer a rare West Coast window into the last great age of marine reptiles.

And yet, their spectacular reign was brief. When the asteroid struck 66 million years ago, the seas dimmed, the food chains collapsed, and even these titans couldn’t outswim extinction.

But in stone, they still roar. Their skeletons—sleek, predatory, impossibly elegant—remind us that Earth’s oceans were once ruled by lizards the size of whales… and that nature occasionally writes stories no novelist would dare invent.

FOSSILS OF THE UPPER CRETACEOUS MOTORCROSS SITE: NANAIMO

Steller's Jay, Cyanocitta stelleri

One of the classic fossil localities on Vancouver Island lies within the Santonian–Maastrichtian (Upper Cretaceous) Haslam Formation at the old Motocross Pit near Brannen Lake, just outside Nanaimo, British Columbia. 

Once an active quarry, the site now hums with the roar of dirt bikes and the scent of gasoline and wet earth carried on the coastal wind. The air is cool and mineral-rich, and if you pause between races, you can catch the distant rush of Benson Creek Falls through the evergreens. 

A smaller gravel operation still works nearby, closer to Ammonite Falls, where shale and sandstone beds of the Nanaimo Group continue to reveal fossils from an ancient seaway that once covered this region. 

Despite its modern transformation, the Motocross Pit remains one of the most storied and scientifically valuable fossil sites of the Nanaimo Group.

We find well-preserved nautiloids and ammonites — Canadoceras, Pseudoschloenbachia, Epigoniceras — the bivalves — Inoceramus, Sphenoceramus— gastropods, and classic Nanaimo Group decapods — Hoploparia, Linuparus. We also find fossil fruit and seeds which tell the story of the terrestrial history of Vancouver Island.

The Motocross Pit locality was first brought to my attention by John Fam, Vice-Chair of the Vancouver Island Paleontological Society (VanPS). John is one of those rare individuals whose enthusiasm for paleontology is matched only by his warmth and generosity. During his years on Vancouver Island, he was an active VanPS member and a key collaborator during my tenure as Chair. Many of the most memorable joint VIPS/VanPS expeditions were sparked by his curiosity, leadership, and infectious passion for fossils.

John grew up just fifteen minutes from the Motocross locality and spent countless hours there collecting specimens with his father. His love of fossils is a family affair—one that continues today with his wife, Grace, and their two young sons, who now share in the same sense of wonder that first drew John to the site.

I first met John many years ago and still remember staying overnight at his parents’ home before a weekend field trip to Jurassic Point. That evening, he shared stories of his early fossil-hunting adventures and walked me through his carefully curated collection—an experience that spoke volumes about his dedication to the science and art of paleontology.

Upper Cretaceous Haslam Fm near Brannen Lake

Inspired by his stories, I later visited the Motocross Pit with my uncle Doug, a kind and curious man who had explored much of the coast but had never seen this fossil treasure so close to home. 

We spent the day walking through time together, tracing the ancient layers of the Cretaceous seafloor. 

When I returned to the site alone this past year, the wind in the trees and the scent of damp shale carried a bittersweet note—reminding me of the joy of that shared day and of one of the best men I have ever known, now gone but never forgotten. 

As I approached the site, there were no people around, so I walked the periphery looking for the bedrock of the Haslam. The rocks we find here were laid down south of the equator as small, tropical islands. They rode across the Pacific heading north and slightly east over the past 80 million years to where we find them today.

Upper Cretaceous Haslam Formation Motocross Pit

Jim Haggart and Peter Ward have each made remarkable contributions to our understanding of the rich molluscan fauna of the Nanaimo Group, the Late Cretaceous sedimentary sequence that records the history of an ancient seaway once spanning much of what is now coastal British Columbia and Washington State.

Both men bring to paleontology a mix of scholarly rigor and adventurous spirit—embodying, in the best sense, that “Indiana Jones” archetype of the field scientist: field-worn boots, weathered notebooks, and an endless curiosity for the deep past. 

Their fieldwork across Vancouver Island, the Gulf Islands, and the San Juan archipelago has provided essential biostratigraphic correlations, linking fossil assemblages across what were once the submerged margins of the Wrangellia Terrane. 

Through careful mapping, fossil collection, and stratigraphic analysis, their work has helped clarify the temporal and environmental relationships among the various formations of the Nanaimo Group, from the Haslam and Extension to the Pender and Geoffrey formations.

Haggart and Ward’s research builds on a long tradition of geologic and paleontological inquiry in the region. Foundational studies by Usher (1952), Matsumoto (1959a, 1959b), and Mallory (1977) established the first detailed taxonomic and biostratigraphic frameworks for these Late Cretaceous faunas. 

Equally significant was the work of Muller and Jeletzky (1970), who untangled the complex lithostratigraphic and biostratigraphic relationships within the Nanaimo Group—providing the bedrock upon which modern interpretations stand.

Together, this lineage of research has transformed the Nanaimo Group from a series of scattered coastal outcrops into one of the best-documented Cretaceous marine sequences in western North America, offering crucial insight into paleogeography, faunal migration, and the dynamic tectonic history of the Pacific margin.

As I walked along the bedrock of the Haslam, a Steller's Jay, Cyanocitta stelleri, followed me from tree to tree making his guttural shook, shook, shook call. 

Instructive, he seemed to be encouraging me, timing his hoots to the beat of my hammer. Vancouver Island truly has glorious flora and fauna.

Fancy some additional reading? Check out a paper published in the Journal of Paleontology back in 1989 by Haggard and Ward on Nanaimo Group Ammonites from British Columbia and Washington State.

In it, they look at the ammonite species Puzosia (Mesopuzosia) densicostata Matsumoto, Kitchinites (Neopuzosia) japonicus Spath, Anapachydiscus cf. A. nelchinensis Jones, Menuites cf. M. menu (Forbes), Submortoniceras chicoense (Trask), and Baculites cf. B. boulei Collignon are described from Santonian--Campanian strata of western Canada and northwestern United States.

Stratigraphic occurrences and ranges of the species are summarized and those taxa important for correlation with other areas in the north Pacific region and Late Cretaceous ammonite fauna of the Indo-Pacific region. Here's the link: https://www.jstor.org/stable/1305358?seq=1

Peter Ward is a prolific author, both of scientific papers and more popularized works. I highly recommend his book Gorgon: Paleontology, Obsession, and the Greatest Catastrophe in Earth's History. It is an engaging romp through a decade's research in South Africa's Karoo Desert.

WINTER LIGHT: NUSFJORD, LOFOTEN

Nusfjord, Lofoten, Norway

In the soft blue twilight of a Lofoten winter, the village of Nusfjord sits cradled between mountains that rise like frozen waves. 

Wooden rorbuer—those classic red fishermen’s cabins—hug the harbour, their walls creaking softly in the cold. 

A sharp, salty breeze drifts through the village, carrying with it the unmistakable tang of drying cod—rich, briny, and threaded with the cold bite of the Arctic sea.

The air is crisp with the scent of the sea and cod drying on wooden racks, rows of fish stiff as boards in the Arctic wind. 

Gulls wheel overhead, their cries echoing off the fjord walls, while beneath the surface, the North Atlantic swirls dark and ancient, shaped by ice, fire, and time. The gulls know a meal is at hand if they can catch you unaware.

Nusfjord, one of Norway’s best-preserved fishing villages, tells a story of the rugged people who live here, the sea and its bounty but also a great geological drama. The stone on which it rests—gneiss and schist—was forged nearly 3 billion years ago, among the oldest rocks in Europe. These are remnants of Earth’s early continental crust, once buried miles below the surface. 

Over eons, tectonic collisions folded, pressed, and recrystallized them, transforming simple sediments into the gleaming banded rocks you see today.

The rugged backdrop of the Lofoten Islands owes its shape to the Caledonian Orogeny, a mountain-building event that occurred some 400 million years ago, when the ancient continents of Laurentia and Baltica collided. The pressures of that collision thrust deep crustal rocks upward, forming mountains that once rivaled the Himalayas. 

Time, glaciers, and relentless coastal erosion have since sculpted those peaks into the steep, knife-edged forms that now cradle Nusfjord like the walls of a stony amphitheatre.

During the last Ice Age, glaciers carved deep U-shaped valleys through these hard rocks, leaving behind the fjords we know today. As the ice retreated roughly 10,000 years ago, the sea flooded these valleys, creating a perfect natural harbour—sheltered from storms, yet open to the rich fishing grounds of the Norwegian Sea. It was this unique geography that first drew Norse fishermen here more than a thousand years ago, setting the stage for Nusfjord’s long relationship with cod.

While the fish still hang to dry each winter—a ritual unchanged for centuries—the rocks whisper stories of an even older world. Every granite ridge and polished outcrop is a page from the deep-time chronicle of our planet. It is icy poetry by all accounts and one of my favourite parts of the world.

In Nusfjord, geology and human history intertwine as seamlessly as sea and sky: a place where the bones of the Earth rise through ice and salt air, and the past is written in both stone and scales.

PETALS FROZEN IN TIME: THE PRINCETON CHERT

It began with a bloom, Florissantia quilchenensis, its petals splayed across a creamy, beige-brown matrix like a fossilized whisper from a warmer world. 

This precious bloom was hard-earned. Covered in dust and sweat, I grinned and held this elusive beauty to the light to take in its exceptional preservation and dusty beauty!

It was day three of my travels. I was hiking the hills around the town of Princeton in the Similkameen region of southern British Columbia, Canada. 

The former mining and railway hub lies at the confluence of the Tulameen into the Similkameen River, just east of the Cascade Mountains. It is dry, arid country covered by native grasslands and low scrub. 

Princeton, BC is located in the traditional territories of the Nlaka’pamux and Syilx (Okanagan) peoples. 

The region has historical significance for the Syilx, particularly the Upper and Lower Similkameen Indian Bands, and has been an important area for gathering red ochre for thousands of years. I had first explored the region looking for red ochre deposits to photograph, always with an eye to the local fossils.

On this particular trip, I was searching for fossils and the iconic flower, Florissantia, in the slopes known locally as Hospital Hill.

A lucky split brought a eureka moment. Is it? Could it be? Yes! Peeling back the layers, I had uncovered a near perfect flower and the treasure I had long been seeking. Searching for Florissantia had brought me to the Princeton area on many occasions but my first was found on this trip. 

Under a hand lens, its details unfurl: each vein etched in silica, each contour revealed with startling fidelity. 

I had uncovered a perfect flower, a time capsule telling us about the landscape as it once was, lush, tropical, and steaming with life.

This singular fossil, preserved in almost impossibly fine detail, is one of the jewels of the Princeton Chert, a fossil treasure hidden in the hills of British Columbia. 

Here, an entire ancient ecosystem—plants, fungi, fish, and the delicate traces of vanished warmth—was captured in stone with such precision that cell walls, stomata, and even parasitic fungi remain visible 48 million years later.

The Princeton Chert lies tucked along the east bank of the Similkameen River, 8.5 km south of the town of Princeton, B.C. At first glance, the exposures of the Allenby Formation appear unassuming: thinly layered bands of shale, coal, and pale chert. 

But within these layers, we've discovered something extraordinary—an anatomically preserved flora, fossilized in three dimensions. Unlike typical compression fossils, these organisms were permeated by silica-rich waters so quickly and so thoroughly that even their internal structures survived.

Since the 1950s, collectors and researchers have pulled back the curtain on this Eocene world, but it was in the 1970s and onward that the Chert achieved global attention. Scientists recognized that the Princeton Chert wasn’t just another fossil site. 

It was a Lagerstätte of unparalleled richness—one of the few places on Earth where entire plant communities are preserved down to the microscopic level.

Thin-sectioned under a microscope, these fossils show xylem vessels, aerenchyma, reproductive organs, pollen, seeds, roots, and fungal pathogens—all exquisitely intact. Few fossil floras in the world rival this clarity.

The Princeton Chert formed in a landscape shaped by fire and water. Its 49 known chert layers, ranging from thin wafers to thick beds over half a metre, alternate with volcanic ash, coal, and shale. Each layer represents a momentary pause in time—a lake or pond basin repeatedly drowned in silica-rich waters after nearby volcanic eruptions.

Radiometric dating now places the site at 48.7 million years old, deep within the Early Eocene Ypresian Stage, a time when Earth’s climate simmered near its all-time warmest. Greenhouse gases were high, ice was nearly absent, and tropical warmth lapped into polar regions.

The Princeton Chert flora thrived in shallow lakes and quiet backwaters. Many species were fully aquatic or semi-aquatic, and the fossils show unmistakable features of plants adapted to waterlogged conditions:

• Reduced vascular tissue (because buoyant plants need little support)
• Aerenchyma—honeycombed air chambers for floatation
• Protoxylem lacunae, ringed by thick-walled cells

Many of these plants have close relatives today:

• Allenbya – a water lily
• Keratosperma – an arum with curling, sculptural leaves
• Alismataceae – water plantains
• Ethela – rush-like monocots and sedges

Seeds, fruits, and roots appear in beautiful profusion. Meanwhile, terrestrial plants—those carried in by floods or dropped by birds—are rare but present.

The chert also preserves snippets of the animals that lived alongside these aquatic gardens. In the overlying shale beds, paleontologists have recovered Amia (bowfins), Amyzon, Libotonius, and even a soft-shelled turtle—a small but telling cast of freshwater neighbours.

One of the most remarkable aspects of the Princeton Chert is its preservation of fungi. Here, we have identified:

• Tar spot fungi parasitizing Uhlia palm leaves
• Cryptodidymosphaerites princetonensis, a mycoparasite attacking the tar spot fungus
• Ectomycorrhizae—the first ever documented fossil mycorrhizal symbiosis with Pinus

In Metasequoia milleri, the Eocene ancestor of modern dawn redwood, mycorrhizal relationships appear nearly identical to those in modern forests. It is as though 50 million years have passed with hardly a change.

The Princeton Chert has attracted generations of paleobotanists, sedimentologists, and fossil enthusiasts, each drawn to its exquisite three-dimensional preservation and its window into Eocene ecosystems. 

Charles William “Chuck” Basinger, a Canadian paleobotanist renowned for his work on anatomically preserved plants and early conifer evolution. His meticulous studies helped illuminate the internal structures of Princeton Chert flora at cellular resolution. 

Ruth A. Stockey, a leading paleobotanist specialising in fossil conifers, seed plants, and reproductive biology, has published (along with her many grad students) extensively on the chert’s gymnosperms and angiosperms, reconstructing entire plants from roots to reproductive organs. 

Together with many collaborators over the decades, these scientists have pieced together a vivid portrait of ancient wetland forests—lush, diverse, and humming with microscopic and macroscopic life. 

The site is also beloved within the fossil-collecting community. The Vancouver Paleontological Society (VanPS) has organized field trips here for decades. 

Many members remember their first visit: crouched on a hot summer slope, poking about the roadcuts, collecting fossil insects and plants. One of the first large scale field trips to the region by the VanPS was part of the first BCPA Symposium held in 1998 at the University of British Columbia in Vancouver. 

Smaller field trips became a regular occurrence, usually one every year or two, and that trend continues. The result of all that exploration is a greater understanding of the many fossil species to be found here.

Dan Bowden of the VanPS has done some wonderful work cataloguing the many fossils found here, with a particularly good eye in identifying the fossil insects. 

These excursions have helped train new generations of citizen scientists, fostering a deep respect for the site’s scientific importance.

If you plan to head to Princeton, be sure to include the Princeton & District Museum on your travels. The museum holds a good selection of the local fossils. It is located at 167 Vermillion Avenue, Princeton, BC, V0X 1W0. You can confirm their house on their website at princetonmuseum.org

Know Before You Go: Exploring the Fossil Lakes of British Columbia

Getting There from Vancouver

• Drive east on Highway 1 through Hope, then continue along Highway 3 (the Crowsnest Highway). The town of Hope offers a good place to stop for a meal and gas up your vehicle.
• Pass through Manning Park and descend into the Similkameen Valley toward Princeton.
• The Princeton Chert itself is on private and protected land; access requires permission and often participation in sanctioned society trips.
• Surface collecting yields a wonderful assortment of fossils. 

FOSSILS, FISH AND FLAMING VOLCANOES: INTERIOR BC'S HISTORIC PAST

A Bird's Eye View of BC's Interior

Once upon a geologic time—about 52 million years ago—British Columbia wasn’t the mountain-studded landscape we know today. 

Instead, imagine a steaming chain of tropical islands floating in a warm inland sea, alive with crocodiles, palm trees, and enough volcanic activity to make any self-respecting geologist swoon.

Welcome to Eocene British Columbia—where the rocks are hot, the fossils are cool, and the story of our province’s ancient past stretches like a spine from north to south, stitched together by layers of lakebed shales and volcanic ash.

Let’s start at the McAbee Fossil Beds, just outside of Kamloops. This UNESCO-designated site is a world-class window into the Eocene Epoch. 

The rocks here formed at the bottom of an ancient lake, gently collecting the remains of leaves, insects, and fish that fluttered or flopped in at inconvenient moments. The preservation is exquisite—delicate leaf veins, dragonfly wings, even the odd fish fin are preserved in glorious, paper-thin shale. It’s like nature’s own scrapbook from the dawn of modern ecosystems.

McAbee Fossil Beds with Dr. Lawrence Yang's Crew

These fossils tell us that McAbee was once warm and lush, home to dawn redwoods, ginkgo trees, and the ancestors of modern maples. 

You can see the wonderfully distinct hoodoos up above the fossil site and in this photo, you can see Dr. Lawrence Yang and crew from a field trip we did there a few years ago.

But McAbee didn't look at all like this when the fossils were laid down. 

Picture tropical rainforests thriving where today you find sagebrush and rattlesnakes. 

Yes—Kamloops was once the Kamloops Rainforest. Try putting that on a postcard.

And McAbee isn’t alone. It’s just one stop on an ancient island arc that spanned the province. 

Head north to Driftwood Canyon near Smithers, where paper-thin fossils of fish and insects record a similar story of subtropical serenity. 

A Tasty Selection of Eocene Fossils from BC

Go south to Quilchena, where you’ll find the same lacustrine (lake-formed) layers yielding fossilized leaves and fish that look like they could still dart away if you poked them. The preservation is outstanding. 

Keep going across the border to Republic, Washington, and you’re still following the same Eocene lake chain—like geological breadcrumbs leading back to a time when the west coast was a simmering stew of volcanoes and freshwater basins.

Two of my favourite Eocene fish fossils from the region are Eohiodon, a genus related to the modern mooneye, found at McAbee and Princeton. And Amyzon aggregatum, a type of sucker fish found in the varved lake sediments near Horsefly.

British Columbia has never been shy about rearranging itself. Back in the Eocene, the region was being pulled, pushed, and smushed by tectonic forces. Volcanic eruptions blanketed lakes with fine ash—excellent for fossil-making but less great for anyone hoping for a sunny day at the beach. 

Over time, these lakes filled with sediment, entombing plants, fish, and insects beneath fine-grained layers that later hardened into shale.

The result: a geological photo album spanning millions of years, now tilted and lifted into the dry hills around Kamloops.

I have only visited once since the Bonaparte First Nation took over management of the McAbee Fossil Beds. I brought them some fossils, scientific papers and shared stories of the history of the site from a paleo perspective. I shared about the folks who first leased the land and worked to expand the site, Dave Langevin and John Leahy. The many field trips there by members of the Vancouver Paleontological Society and other groups. The site has a rich fossil history deep in time but also in the last 30 years.  

Eocene Fossil Fish from McAbee

They graciously allowed me to bring some folk up to explore and shared their desire to create a visitor and research center, enhancing public programming with Indigenous cultural activities. 

The Nation aims to highlight the scientific and cultural significance of the area, with a long-term goal of making it a premier Indigenous destination. 

Kneeling in that parched, golden landscape, it’s hard to imagine it once echoed with the croaks of ancient frogs and the buzz of tropical insects. 

But each fossil leaf, precious fossilized feather, March Fly and dragonfly wing at McAbee whispers the same improbable truth: British Columbia was once a lush archipelago of volcanic islands in a balmy world, a far cry from today’s ski slopes and spruce forests.

These sites hold a special place in my heart as they are some of the few that I visited as a teen with my mother and sister. I made repeated trips over the years as the Chair of the Vancouver Paleontological Society, but those early memories are especially dear to me.

As I drive through the Thompson Plateau and see those striped outcrops of shale, I give them a thoughtful nod. They’re the leftovers of a long-vanished paradise that remains a fossil treasure trove today.
