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.

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.

Paleo-coordinates: 44° 35′ 46″ N, 51° 52′ 53″ E.

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.

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.

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

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.

A DELIGHTFUL VISIT AND UNEXPECTED METASEQUOIA

Metasequoia sp., collection of Judy Hill
There is something deeply comforting about encountering a familiar fossil in the company of wonderfully engaging friends.

Yesterday delivered both gifts at once. I wandered into the Judy Hill Gallery on Vancouver Island—a place I enjoy visiting to soak in its stunning collection of Pacific Northwest Coast art and to chat with the gallery’s warm, knowledgeable team.

As we talked, Judy Hill brought out a remarkable treasure: a beautifully preserved Metasequoia fossil.

Its story is as intriguing as the specimen itself. Originally collected under the assumption it might be a petroglyph—its true origins a mystery—it was entrusted to Judy for safekeeping.

Of course it was. Judy is the heart and soul of the Judy Hill Gallery in Duncan, British Columbia, a family-run haven that has championed Indigenous art for more than 30 years. She is as lovely as she is learned, known not only for her expertise but for the kindness, generosity, and deep respect she brings to every relationship.

Perhaps because of this, people bring their curiosities, their heirlooms, and their unusual finds to her, knowing they will be honoured and protected.

And so, in the quiet magic of an impromptu morning visit, this Metasequoia sp. fossil came into view—another beautiful piece of natural history finding its way, as so many treasures do, to Judy’s caring hands. 

Metasequoia, McAbee Fossil Beds
The fossil is an ancient cousin to one of the many native trees on Vancouver Island and BC's mainland, the lovely conifer Metasequoia glyptostroboides — the dawn redwood. 

Of this long lineage, the sole surviving species in the genus Metasequoia and one of three species of conifers known as redwoods, is Metasequoia glyptostroboides

Metasequoia are the smaller cousins of the mighty Giant Sequoia, the most massive trees on Earth. 

As a group, the redwoods are impressive trees and very long-lived. The President, an ancient Giant Sequoia, Sequoiadendron giganteum, and granddaddy to them all has lived for more than 3,200 years. While this tree is named The President, a worthy name, it doesn't really cover the magnitude of this giant by half.   

This tree was a wee seedling making its way in the soils of the Sierra Nevada mountains of California before we invented writing. It had reached full height before any of the Seven Wonders of the Ancient World, those remarkable constructions of classical antiquity, were even an inkling of our budding human achievements. 

It has outlasted them all save the Great Pyramid of Giza, the oldest and last of those seven still standing, though the tree has faired better. Giza still stands but the majority of the limestone façade is long gone.

Aside from their good looks (which can really only get you so far), they are resistant to fire and insects through a combined effort of bark over a foot thick, a high tannin content and minimal resin, a genius of evolutionary design. 

While individual Metasequoia live a long time, as a genus they have lived far longer. 

Like Phoenix from the Ashes, the Cretaceous (K-Pg) extinction event that wiped out the dinosaurs, ammonites and more than seventy-five percent of all species on the planet was their curtain call. The void left by that devastation saw the birth of this genus — and they have not changed all that much in the 65 million years since. Modern Metasequoia glyptostroboides looks pretty much identical to their late Cretaceous brethren.

Dawn Redwood Cones
They are remarkably similar to and sometimes mistaken for Sequoia at first glance but are easily distinguishable if you look at their size (an obvious visual in a mature tree) or to their needles and cones in younger specimens. 

Metasequoia has paired needles that attach opposite to each other on the compound stem. 

Sequoia needles are offset and attached alternately. Think of the pattern as jumping versus walking with your two feet moving forward parallel to one another. 

Metasequoia needles are paired as if you were jumping forward, one print beside the other, while Sequoia needles have the one-in-front-of-the-other pattern of walking.

The seed-bearing cones of Metasequoia have a stalk at their base and the scales are arranged in paired opposite rows which you can see quite well in the visual above. Coast redwood cone scales are arranged in a spiral and lack a stalk at their base.

Although the least tall of the redwoods, it grows to an impressive sixty meters (200 feet) in height. It is sometimes called Shui-sa, or water fir by those who live in the secluded mountainous region of China where it was rediscovered.

Fossil Metasequoia, McAbee Fossil Beds
Metasequoia fossils are known from many areas in the Northern Hemisphere and were one of my first fossil finds as a teenager. 

And folk love naming them. More than twenty fossil species have been named over time —  some even identified as the genus Sequoia in error — but for all their collective efforts to beef up this genus there are just three species: Metasequoia foxii, Metasequoia milleri, and Metasequoia occidentalis.

During the Paleocene and Eocene, extensive forests of Metasequoia thrived as far north as Strathcona Fiord on Ellesmere Island and sites on Axel Heiberg Island in Canada's far north around 80° N latitude.

We find lovely examples of Metasequoia occidentalis in the Eocene outcrops at McAbee near Cache Creek, British Columbia, Canada. I shared a photo here of one of those specimens. 

Once this piece dries out a bit, I will take a dental pick to it to reveal more of the teaser fossils peeking out.

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

While the Metasequoia and other fossils found here are 52-53 million years old, the genus is much older. It is quite remarkable that both their fossil and extant lineage were discovered in just a few years of one another. 

Metasequoia was first described as a new genus from a fossil specimen found in 1939 and published by Japanese paleobotanist Shigeru Miki in 1941. Remarkably, the living version of this new genus was discovered later that same year. 

Professor Zhan Wang, an official from the Bureau of Forest Research was recovering from malaria at an old school chum's home in central China. His friend told him of a stand of trees discovered in the winter of 1941 by Chinese botanist Toh Gan (干铎). The trees were not far away from where they were staying and Gan's winter visit meant he did not collect any specimen as the trees had lost their leaves. 

The locals called the trees Shui-sa, or water fir. As trees go, they were reportedly quite impressive with some growing as much as sixty feet tall. Wang was excited by the possibility of finding a new species and asked his friend to describe the trees and their needles in detail. 

Emboldened by the tale, Wang set off through the remote mountains to search for his mysterious trees and found them deep in the heart of  Modaoxi (磨刀溪; now renamed Moudao (谋道), in Lichuan County, in the central China province of Hubei. He found the trees and was able to collect living specimens but initially thought they were from Glyptostrobus pensilis (水松). 

A few years later, Wang showed the trees to botanist Wan-Chun Cheng and learned that these were not the leaves of s Glyptostrobus pensilis (水松 ) but belonged to a new species. 

While the find was exciting, it was overshadowed by China's ongoing conflict with the Japanese that was continuing to escalate. With war at hand, Wang's research funding and science focus needed to be set aside for another two years as he fled the bombing of Beijing. 

When you live in a world without war on home soil it is easy to forget the realities for those who grew up in it. 

Zhan Wang and his family lived to witness the 1931 invasion of Manchuria, then the 1937 clash between Chinese and Japanese troops at the Marco Polo Bridge, just outside Beijing. 

That clash sparked an all-out war that would grow in ferocity to become World War II. 

Within a year, the Chinese military situation was dire. Most of eastern China lay in Japanese hands: Shanghai, Nanjing, Beijing, Wuhan. As the Japanese advanced, they left a devastated population in their path where atrocity after atrocity was the norm. Many outside observers assumed that China could not hold out, and the most likely scenario was a Japanese victory over China.

Yet the Chinese hung on, and after the horrors of Pearl Harbor, the war became genuinely global. The western Allies and China were now united in their war against Japan, a conflict that would finally end on September 2, 1945, after Allied naval forces blockaded Japan and subjected the island nation to intensive bombing, including the utter devastation that was the Enola Gay's atomic payload over Hiroshima. 

With World War II behind them, the Chinese researchers were able to re-focus their energies on the sciences. Sadly, Wang was not able to join them. Instead, two of his colleagues, Wan Chun Cheng and Hu Hsen Hsu, the director of Fan Memorial Institute of Biology would continue the work. Wan-Chun Cheng sent specimens to Hu Hsen Hsu and upon examination realised they were the living version of the trees Miki had published upon in 1941. 

Hu and Cheng published a paper describing a new living species of Metasequoia in May 1948 in the Bulletin of Fan Memorial Institute of Biology.

That same year, Arnold Arboretum of Harvard University sent an expedition to collect seeds and, soon after, seedling trees were distributed to various universities and arboreta worldwide. 

Today, Metasequoia grow around the globe. When I see them, I think of Wang and all he went through. He survived the conflict and went on to teach other bright, young minds about the bountiful flora in China. I think of Wan Chun Cheng collaborating with Hu Hsen Hsu in a time of war and of Hu keeping up to date on scientific research, even published works from colleagues from countries with whom his country was at war. 

Deep in my belly, I ache for the huge cost to science, research and all the species impacted on the planet from our human conflicts. Each year in April, I plant more Metasequoia to celebrate Earth Day and all that means for every living thing on this big blue orb.

ECHOES IN STONE: WASHINGTON GEOLOGY

Washington State Forest
Two hundred million years ago, what we now call Washington wasn’t Washington at all. 

It was two drifting islands — fragments of a wandering continent slowly inching their way west across the ancient ocean. 

They were vagabonds, carried on tectonic currents until, at last, they collided with the North American continent and made themselves at home.

That restless motion has never stopped. The land still breathes — slow, tectonic breaths that subtly reshape the surface of the Pacific Northwest. Every so often, that breath shudders. 

We feel it in an earthquake, a reminder that the forces that built the land are still at work, deep below our feet. The great plates grind and twist, pushing mountains skyward and sliding California ever so slightly toward the North Pole. Hello, Baja-BC.

It’s this long, dynamic dance — the great continental waltz — that sculpted the ridges, folded valleys, and mountain walls we see today. And it’s also what preserved an ancient world beneath our boots: the subtropical swamps and deltas of the Chuckanut Formation, a geological tapestry stretching some 3,000 metres thick along Chuckanut Drive near Bellingham.

Islands Riding Tectonic Plates
Layer upon layer of sandstone, siltstone, mudstone, and conglomerate record the rhythms of rivers that once coursed through a lush, steaming delta. The lower strata date back roughly 56 million years, at the very end of the Paleocene. 

The upper layers push into the early Eocene, a time when Earth was warmer and wetter than it has been since. Imagine, if you can, not the misty evergreens and glacial peaks of today, but a subtropical floodplain, dense with palms, ferns, and broad-leaved trees. 

Picture the bayou country of the Lower Mississippi, but stretching across what is now the Pacific Northwest.

This was a land of life. Ancient trees towered overhead. Vines tangled in the swamp air. The Chuckanut flora tells us of a greenhouse Earth — plants whose modern cousins thrive in Central America and southern Mexico flourished here, under the same sun that today glints off Mount Baker’s glaciers. 

Every fallen branch, every leaf buried in fine silt became part of the rock record, sealing in the whispers of an ancient climate: its humidity, rainfall, and heat.

But the plants are only part of the story. In rare and beautiful moments, the Chuckanut Formation captures motion — the fleeting steps of animals caught forever in stone. These are the Sumas Eocene trackways, discovered after landslides near Sumas in 2009. 

The Ancient Bayou of Washington State 
Among them are footprints from small shorebirds, the imprints of early equids, and tracks of curious, blunt-footed herbivores belonging to the now-extinct Orders Pantodonta and Dinocerata. 

Together, they sketch a portrait of life 50 million years ago: herds and flocks wandering the muddy margins of rivers, where soft sediment briefly held their weight before drying, hardening, and turning to stone.

One of the most striking finds is that of a delicate shorebird trackway, each print barely larger than a thumbprint, pressed into what was once the bank of a lazy river. 

It’s joined by faint impressions from an early horse-like mammal and, in other sites such as Racehorse Creek, the formidable three-toed stamp of Diatryma — a flightless bird taller than a man, and every bit as formidable as its dinosaurian cousins.

These fossil trackways are precious not just for their rarity but for what they reveal: a moment of life, caught mid-step. Unlike bones, which tell us who lived here, tracks tell us how they lived — where they walked, how they moved, even how they interacted. They are the fossilized choreography of an ancient ecosystem, preserved in mud and time.

Mt. Baker, Washington
These traces are studied and safeguarded by researchers such as George Mustoe and his colleagues, who carefully collected the Sumas trackways and brought them to the Burke Museum in Seattle. 

There, under controlled light and the quiet reverence of display cases, visitors can stand face-to-face with the footprints of creatures that trod the Pacific Northwest long before the Cascades rose above the horizon.

The landscape along Chuckanut Drive may look serene now — the sandstone cliffs honeycombed by ferns, the sea glittering beyond. 

But beneath every weathered ledge and outcrop lies a record of turbulence and transformation: continents colliding, mountains rising, rivers changing course, and life adapting in the wake.

This is land that is now forests and tides, but was once swamps and subtropical rain. The fossils remind us that the ground beneath us has always been moving, always changing, and always keeping its secrets — until the rock, split open by time or by curiosity, whispers them back into the light.

THE GREAT CLALLAM BAY FOSSIL HEIST

Vertipecten fucanus (Dall, 1900)
Some water-worn samples of the bivalve Verdipectin fucanus, Clallam Formation, Clallam Bay, Washington State. Miocene.

It all began one gloriously sunny summer weekend when the planets aligned, the calendar gods smiled, and my mother and I were simultaneously free. 

Naturally, this meant one thing: we were going fossil hunting. I still get out collecting regularly but back in the day it was every weekend of the year with the bigger trips planned a few years in advance. 

Many of those were "reckie trips" scouting out new localities. The Olympic Peninsula was duly scouted and now it was back to the regular haunts. 

We rattled down through Port Angeles and set up camp at the Lyre River—mosquitoes, campfire smoke, and all the rustic feels

I took Mom on a grand tour of my favourite haunts: Majestic Beach (where we found some amazing fossil whale verts), a private-land site with ghost shrimp claws and urchins (with permission), and finally down to Clallam Bay and its dreamy beach exposures.

The Clallam Formation stretches along the north coast of the Olympic Peninsula, tracing the rugged edge of the Strait of Juan de Fuca from Slip Point at the eastern end of Clallam Bay to the headland of Pillar Point. Here, sandstone beds push the coastline outward in a subtle bulge, their weathered flanks dropping abruptly to a broad, wave-washed bedrock platform.

Pillar Point, Clallam Bay
Imagine standing on that foreshore: waves crash rhythmically against the stone, sending up bursts of cool spray. The surf’s deep, steady thunder pulses underfoot, while the sharper cries of gulls wheel above, carried on the wind. 

The air is rich with the briny scent of kelp and cold saltwater, a sharp, clean smell that settles in the back of the throat. Each retreating wave leaves a gleaming sheen on the rock, swirling with foam before sliding back to the sea.

Its cliffs and tidal benches have long drawn geologists—and especially paleontologists—who were captivated by the formation’s abundance of beautifully preserved fossils. 

William Healey Dall, a pioneering American geologist and paleontologist whose career spanned more than six decades. Dall loved to explore this rugged bit of coastline, studying and describing many of the mollusks now known from the Clallam Formation, adding his work to the early scientific tapestry woven from these windswept rocks.

He became one of the most prolific describers of North Pacific mollusks, naming hundreds of new species—from marine snails and clams to chitons—many of which still bear the names he assigned or honour him through genera such as Dallina and Dallididae. His work laid much of the early scientific foundation for the paleontology of the Pacific Coast.

Retracing his footsteps and to catch the tides just right, we collected in the early afternoon, blissfully unaware that we were setting up the perfect comedy plot twist. 

After a full day of hauling home the ocean’s Miocene leftovers, we decided to stash some of our fossil booty under a log—just until morning. A little paleo treasure cache. Perfectly safe. Nothing could possibly go wrong.

The next morning, we strolled back down the beach, coffees in hand, ready to retrieve our hoard like triumphant pirates.

Enter: A very enthusiastic gaggle of high school students.

There they were, marching toward us, each clutching a fossil like they’d just won the geological lottery. “Look what we found!” they cried, beaming, displaying our carefully cached treasures.

Yes. Our stash. Our carefully curated, lovingly positioned, absolutely-not-meant-for-public-consumption stash.

But honestly? They were so thrilled, we couldn’t help but be charmed. Besides, most of what I collect ends up in museums or teaching collections anyway. These young fossil hunters had simply… expedited the process. Efficient, really.

We gathered the Verdipectin together for one glamorous group photo, wished the kids well, and sent them off with pockets full of deep time. 

And our grand prize for the weekend? Some very fetching water-worn whale vertebrae—one of which was briefly enscripted into service as the crown of the King of the Lemon People, while my mother created elaborate beach sculptures to our shared amusement.. All in all, a perfect weekend.

FOSSILS OF EGYPT — TRACING ANCIENT LIFE FROM SEA TO SAND

Spinosaurus, Fukui Prefectural Dinosaur Museum
Egypt is often celebrated for its pyramids and pharaohs, but beneath those golden sands lies a much older and equally astonishing legacy — the fossil record of a land that has shifted from lush tropical forests to inland seas and back again.

From the Western Desert to the Fayum Depression and Wadi Al-Hitan (the Valley of the Whales), Egypt’s rocks preserve nearly 100 million years of life on Earth, from the Cretaceous dinosaurs that roamed its river plains to the Eocene whales that swam through the Tethys Ocean.

Over the past few posts, we've looked at the geological wonders of Egypt. Here is a deeper look at some of the many interesting fossil species to be found in this rich paleontological playground.

Petrified Wood — A Forest Turned to Stone

Across Egypt’s deserts, the ground often glitters with fossilized trees. The Petrified Wood Protectorate near New Cairo, along the Cairo–Suez road, and wide stretches of the Western Desert are carpeted in ancient trunks and branches turned to stone.

These fossil forests are vivid evidence that much of Egypt was once a humid, tropical landscape, rich with vegetation. The trees, buried in sediments and permineralized over millions of years, became exquisitely preserved in silica. Today, their polished cross-sections shimmer with bands of reds, browns, and golds — a striking reminder of the region’s deep ecological transformations.

Reptiles of the Fayum — Turtles, Crocodiles, and Giants — The Fayum Depression has yielded a wealth of Eocene reptile fossils that speak of a warm, watery world teeming with life. Land tortoises like Testudo ammon roamed the ancient floodplains, while river turtles such as Podocnemis blanckenhorni and Stereogenys pelomedusa swam through slow-moving channels. 

Even more dramatic are the remains of Gigantophis, one of the largest snakes ever discovered, and Tomistoma, a crocodile-like predator from the Qasr al-Sagha Formation. These reptiles hint at an ecosystem that blended mangroves, lagoons, and river deltas — a mosaic of habitats where both freshwater and marine species thrived.

Birds of an Ancient Delta — The Fayum’s fossil beds also record an impressive diversity of Eocene and Oligocene birdlife. The ancient wetlands once supported ospreys (Pandionidae), flamingos (Phoenicopteridae), herons, cranes (Gruidae), cormorants (Phalacrocoracidae), and even the massive shoebilled stork (Balaenicipitidae).

These avian fossils, comparable to species found today around Lake Victoria and the Upper Nile, suggest a vibrant, subtropical ecosystem rich in lakes and marshes — a far cry from the arid desert we see today.

Mammals of the Fayum — Whales, Elephants, and Early Primates

The mammalian fossils of Egypt are among the most extraordinary in the world. In the Fayum Depression and at Wadi Al-Hitan, paleontologists have uncovered a sweeping record of evolution from land to sea and from primitive mammals to the ancestors of modern species.

At Wadi Al-Hitan, skeletons of early whales — Basilosaurus isis, Dorudon atrox, and Phiomicetus — preserve a pivotal evolutionary moment when whales transitioned from walking on land to swimming in the sea. Their long, streamlined bodies and tiny hind limbs are beautiful testaments to nature’s adaptability.

Meanwhile, the terrestrial Fayum deposits reveal a menagerie of early mammals:

  • Arsinoitherium, a massive, rhinoceros-like creature with twin horns;
  • Moeritherium, a semi-aquatic ancestor of elephants and manatees;
  • Palaeomastodon and Phioma, early proboscideans bridging the gap to modern elephants;
  • and Megalohyrax, a giant relative of today’s small hyrax.

Carnivorous mammals also prowled these Eocene landscapes — species like Apterodon, Pterodon, and Hyaenodon, formidable predators of their time.

The Fayum Primates — Our Ancient Cousins — Among the Fayum’s most scientifically valuable discoveries are the fossils of early primates, bridging the gap between ancient prosimians and modern monkeys and apes.

From the lower sequence, we find forms like Oligopithecus savagei and Qatrania wingi, while the upper sequence preserves Catopithecus browni, Proteopithecus sylvia, and the well-known Apidium and Parapithecus species.

Perhaps most famous is Aegyptopithecus zeuxis, a small tree-dwelling primate with forward-facing eyes and a relatively large brain. It is often cited as one of the earliest known ancestors of modern Old World monkeys and apes — and, by extension, of humans.

These fossils from the Jebel Qatrani Formation provide an unparalleled window into primate evolution roughly 35 to 30 million years ago, when Africa’s tropical forests were home to our distant kin.

Dinosaurs of the Cretaceous Desert — Long before the whales and primates, Egypt’s landscape was dominated by Cretaceous dinosaurs. The Bahariya Formation and Nubian Sandstone have yielded fossils of immense sauropods and ferocious theropods, painting a vivid picture of life 95 million years ago.

Among the stars of this ancient cast are:

  • The long-necked Aegyptosaurus and Paralititan, massive plant-eating sauropods;
  • The sleek, predatory Bahariasaurus, Carcharodontosaurus, and Deltadromeus;
  • The semi-aquatic Spinosaurus, with its iconic sail-backed spine — perhaps one of the most famous dinosaurs to ever emerge from African rock; and Mansourasaurus, a titanosaur discovered more recently, helping to link Africa’s late Cretaceous fauna with those of Europe and Asia.

These finds demonstrate that Egypt was once a fertile delta world of rivers and floodplains, where dinosaurs thrived long before the Sahara turned to sand.

Egypt’s Fossil Sites — Portals Through Time — Key fossil localities across the country continue to reveal Egypt’s ancient ecosystems:

  • Wadi Al-Hitan — Eocene marine fossils, including whales and sea cows.
  • Fayum Depression — rich terrestrial and freshwater deposits with early mammals and primates.
  • Bahariya Formation — famous for Cretaceous dinosaurs and early vertebrates.
  • Jebel Qatrani Formation — Oligocene primates and proboscideans.
  • Qasr el Sagha Formation — reptiles, turtles, and early crocodilians.
  • Upper Cretaceous Phosphates and Variegated Shale — marine invertebrates and early fish.
  • Moghra Oasis — Miocene fossils bridging the gap between ancient and modern fauna.
  • Queseir Formation — Upper Cretaceous (Campanian) deposit in the Kharga oasis of the Southwestern Desert where the first side-necked turtle Khargachelys caironensis can be found

Egypt’s fossils offer a spectacular narrative of evolution, climate, and change — from swampy Cretaceous river deltas to lush Eocene seas and forests, to the deserts we see today. 

Each discovery connects the story of Earth’s deep past with the land of the Pharaohs, revealing that Egypt’s most enduring monuments are not her pyramids, nor her simple blocks of stone, but the fossils buried them

WADI AL-HITAN: VALLEY OF THE WHALES

Fossil Whale Skeleton, Wadi Al-Hitan
Egypt’s Eocene limestones captivate geologists and paleontologists from around the world. 

These pale, fossil-rich rocks hold the story of an ancient sea and the remarkable creatures that once swam through it.

Modern fieldwork in the Fayum Depression, Wadi Al-Hitan — the Valley of the Whales — and the outcrops near Giza and Cairo is revealing how the shoreline of the Tethys Ocean shifted over tens of millions of years — and how life adapted as land and sea traded places again and again.

Researchers from the Egyptian Geological Museum, the University of Michigan, and Cairo University are combining cutting-edge tools with time-honored field methods. Satellite imaging and drone photogrammetry provide sweeping, high-resolution views of the fossil beds, while detailed stratigraphic logging, sediment sampling, and fossil excavation bring the story into focus layer by layer.

Fossil Whale from Wadi Al-Hitan
The work reveals a stunning environmental transformation. 

The lower rock units record shallow marine deposits packed with Nummulites, corals, and mollusks — life that thrived in the warm, clear waters of the early Eocene Tethys. 

Above these layers, the sediments change in both color and character, grading upward into deltaic and freshwater deposits filled with the fossils of turtles, crocodiles, and early land mammals. It is a geological diary of Egypt’s slow emergence from sea to land.

Wadi Al-Hitan — The Valley of the Whales

Wadi Al-Hitan — The Valley of the Whales
Nestled deep in Egypt’s Western Desert, about 150 kilometers southwest of Cairo, lies Wadi Al-Hitan, one of the world’s most extraordinary fossil sites. 

Once part of the vast Tethys seaway, this now-arid valley was a shallow coastal lagoon some 40 to 50 million years ago, during the Eocene.

Here, teams of paleontologists meticulously map and preserve the articulated skeletons of ancient whales — including Basilosaurus isis and Dorudon atrox — whose bones often lie exactly where the animals came to rest on the seafloor. 

Over time, they were entombed in fine-grained sandstone and limestone, preserving everything from vertebrae and skulls to delicate ribs and vestigial hind limbs.

The surrounding rocks tell a parallel story. Their alternating layers of sandstone, marl, and limestone record shifts in sea level and climate — tidal flats giving way to open marine conditions, then to lagoons choked with vegetation and early mangroves. 

Geochemists analyze the isotopic composition of these sediments to reconstruct ancient seawater temperatures and salinity, while microfossil specialists examine foraminifera and ostracods under the microscope to determine just how deep and warm the waters once were.

Wadi Al-Hitan — The Valley of the Whales
Wadi Al-Hitan’s fossil bounty extends beyond whales. 

The valley has yielded remains of sharks, sawfish, rays, sea cows (Sirenia), turtles, crocodiles, and even early land mammals, offering a vivid snapshot of an ecosystem in transition — one of the last great marine habitats before North Africa began its slow drift toward desert.

The Valley of the Whales is a UNESCO World Heritage Site, protected both for its breathtaking fossil record and its haunting desert beauty. 

Walking through it feels like time travel: the sandstone cliffs glow golden in the sun, and the bones of whales lie half-exposed in the sand — silent witnesses to a vanished ocean. It is a peaceful place to visit. Bone dry, barren but with a rich history.

Fossil Whale from Wadi Al-Hitan
Every fossil, every layer of sediment adds a new brushstroke to the portrait of Egypt’s Eocene world — a subtropical paradise where whales swam through mangroves, coral reefs teemed with life, and the ancestors of modern elephants grazed along the shore.

Beneath the desert sands, these rocks still whisper the story of 50 million years of evolution, of seas that rose and fell, and of creatures that bridged the worlds of land and water — all written in stone.
