SPISULA FOSSIL CLAMS FROM HAIDA GWAII
These fossil bivalves belong to the surf clam lineage, a group well adapted to shallow, energetic marine environments with shifting sands and strong wave action.
Their robust, equivalve shells and streamlined form speak to a life spent burrowed just beneath the sediment surface, filtering seawater for food while riding out constant motion above.
The Skonun Formation preserves a rich snapshot of nearshore marine life along the northeastern Pacific margin during the Miocene, roughly 23 to 5 million years ago.
At that time, Haida Gwaii lay along an active tectonic edge, with sediments accumulating in coastal and shelf settings influenced by currents, storms, and abundant nutrient flow.
Fossils such as Spisula praecursor help us reconstruct these dynamic environments, offering clues about water depth, substrate type, and even paleoclimate.
These particular specimens came from a single block only accessible on a falling tide. Timing, as ever, was everything—and the tide had other ideas.
The excavation involved equal parts determination and seawater, leaving both collector and fossils thoroughly soaked. Still, there is something fitting about getting wet while freeing marine clams from their ancient shoreline, a small reminder that fieldwork often mirrors the environments we are trying to understand.

A LINEAGE OF GIANTS: MEET THE IRISH ELK
![]() |
| Irish Elk, Megaloceros giganteus |
The tall grass parts in slow ripples, stirred by a warm evening breeze—then by something far larger. An Irish Elk steps into view, a towering ghost from deep time, its silhouette edged with gold.
This magnificent deer—Megaloceros giganteus—was not, in fact, strictly Irish, nor truly an elk.
It was a giant among cervids, a member of a lineage that roamed from Ireland to Siberia across vast Ice Age steppes. But Ireland’s bogs preserved their remains so exquisitely that the name stuck, and so did the awe.
Irish Elk fossils appear in abundance in the peatlands of Ireland, the loess plains of Eastern Europe, and far into Central Asia. Their lineage traces back to the genus Megaloceros, a group of large deer that emerged around two million years ago.
What made M. giganteus the superstar of its clan? Two words: monumental antlers.

| Irish Elk, Muséum National d'Histoire Naturelle, Paris |
When these massive antlers were unearthed centuries ago, early naturalists were convinced they belonged to mythical beasts or antediluvian monsters.
The truth turned out to be even better: a deer so grand it nearly defied imagination.
Despite their size and majesty, Irish Elk were true deer, closely related to fallow deer and part of an ancient and diverse cervid family. Their bodies were robust, their legs strong and built for open ground, where visibility mattered and where their spectacular antlers could be displayed in their full glory.
But evolution is a dance with the environment, and as the Pleistocene climate fluctuated, the lush grasslands they depended on began to shrink. Their decline wasn’t sudden but drawn out, a slow waltz toward extinction.
The last of these giants fell only a short time ago. We do not know the exact date but the fossils share their stories as more and more are found. The youngest known fossils come from Siberia and date to about 7,700 years ago—well after most Ice Age megafauna had disappeared.

A giant deer with enormous antlers was increasingly out of place in a world thick with trees and rife with hunters.
Climate change, habitat loss, and possibly selective hunting all nudged the Irish Elk toward its final chapter.
They are one of these species that have been talked about as contenders for using DNA to bring them back.
Today the Irish Elk lives on in museum halls, in bog-darkened bones, and in our imaginations—a giant stepping through grass, pausing on a Pleistocene hillside as if it might turn its head toward us at any moment. There are several Irish Elk in collections and on display at museums around the world where you can view them at your leisure.
A particularly impressive specimen is on view at the Muséum National d'Histoire Naturelle, Paris. The museum is a personal favourite of mine and worthy of a visit for its rich history and marvelous fossils, including the Irish Elk you see in the photo above. There are also wonderful examples in the British Museum in London, also worthy of a visit.
The sheer grandeur of their size is sure to impress you! These beauties are a reminder that the world once held creatures both familiar and impossibly grand.

A TRILOBITE'S LAST MEAL REVEALED
![]() |
| Orygmaspis (Parabolinoides) contracta with gut structure |
And what is most exciting about this specimen is that there is clear preservation of some of the gut structures preserving this trilobite's last meal.
Documentation of non- or weakly biomineralizing animals that lived during the Furongian is essential for a comprehensive understanding of the diversification of metazoans during the early Palaeozoic.
Biomineralization, biologically controlled mineralization, occurs when crystal morphology, growth, composition, and location is completely controlled by the cellular processes of a specific organism. Examples include the shells of invertebrates, such as molluscs and brachiopods. The soft bits of those same animals tend to rot or be scavenged long before mineralization or fossilization can occur — hence, we find less of them.
So, not surprisingly, the fossil record of soft-bodied metazoans is particularly scarce for this critical time interval. To date, the fossils we do have are relatively rare and scattered at a dozen or so localities worldwide.
![]() |
| Location and stratigraphy of the Fossil Locality |
This specimen was found in Upper Cambrian exposures in the Clay Creek section at the top of the left fork of the ravine below Tanglefoot Mountain, 20 km northeast of Fort Steele.
It was the keen eyes of Chris Jenkins who noticed the interesting structures worthy of exploration.
Lerosey-Aubril along with colleagues, Patterson, Gibb and Chatterton, published a great study on this trilobite in Gondwana Research, February 2017.
Their work looked at this new occurrence of exceptional preservation in Furongian (Jiangshanian) strata of the McKay Group near Cranbrook, British Columbia, Canada. Their study followed up on the work of Chatterton et al. studying trilobites with phosphatised guts in this same 10-m-thick interval.
Lerosey-Aubril et al.'s paper looked at two stratigraphically higher horizons with soft-tissue preservation. One yielded a ctenophore and an aglaspidid arthropod, the other a trilobite with a phosphatised gut belonging to a different species than the previously described specimens.
![]() |
| Undetermined ctenophore |
The aglaspidid belongs to a new species of Glypharthrus, and is atypical in having twelve trunk tergites and an anteriorly narrow ‘tailspine’. These features suggest that the tailspine of aglaspidids evolved from the fusion of a twelfth trunk segment with the telson.
They also confirm the vicissicaudatan affinities of these extinct arthropods. Compositional analyses suggest that aglaspidid cuticle was essentially organic with a thin biomineralised (apatite) outer layer.
Macro imagery of the trilobite reveals previously unknown gut features — medial fusion of digestive glands — possibly related to enhanced capabilities for digestion, storage, or the assimilation of food.
These new fossils show that conditions conducive to soft-tissue preservation repeatedly developed in the outer shelf environment represented by the Furongian strata near Cranbrook. Future exploration of the c. 600-m-thick, mudstone-dominated upper part of the section is ongoing by Chris New, Chris Jenkins and Don Askey. There work and collaboration will likely result in more continued discoveries of exceptional fossils.

AMMONITES IN CONCRETION
But then you notice the delicious hints: a spiral ghosting through the surface, a faint rib, a seam where time is ready to split wide open—it's magic!
Ammonites, long extinct cephalopods, so often appear this way because, shortly after death, their shells became chemical centres of attraction on the seafloor.
As the soft tissues decayed, they altered the surrounding sediment, triggering minerals—often calcium carbonate or iron-rich compounds—to precipitate rapidly around the shell.
This early cementation formed a concretion, a protective stone cocoon that hardened long before the surrounding mud was compressed into rock. While everything around it flattened, cracked, and distorted under pressure, the ammonite inside remained cradled and whole.
What you see here is a gathering of these time capsules: a cluster of ammonites preserved in their concretions, each one split or weathered just enough to reveal the coiled story within.
Some are neatly halved, spirals laid bare like fingerprints from ages past; others are only just beginning to show themselves, teasing their presence beneath rough stone skins.
Together, they tell a familiar fossil-hunter’s tale—of patience, sharp eyes, and the quiet thrill of knowing that a simple rock can hold an ancient ocean inside.

BRYCE CANYON NATIONAL PARK
![]() |
| Bryce Canyon National Park |
The hoodoos rise by the tens of thousands, slender spires and stacked pinnacles arranged in amphitheatres that curve like giant bowls scooped from the Paunsaugunt Plateau.
Seen from the air, their geometry becomes mesmerizing: rows and clusters, corridors and cul-de-sacs, each column subtly different, each telling its own long, patient story.
These improbable forms are the product of relentless, delicate violence. Bryce’s hoodoos are sculpted from the Claron Formation, a sequence of sedimentary rocks laid down between about 50 and 35 million years ago, when this high plateau was a landscape of lakes, rivers, and floodplains.
Limestone, mudstone, and siltstone stacked layer upon layer, later lifted skyward as the Colorado Plateau rose. What followed was not a single dramatic event, but millions of freeze–thaw cycles—water seeping into cracks by day, freezing and expanding by night—paired with rain, snowmelt, and gravity’s quiet insistence.
From the aerial view, colour tells the chemistry of the stone. Iron oxides stain the hoodoos in fiery reds and oranges, while manganese adds purples and lavenders that deepen as shadows lengthen.
Pale caps of harder rock perch atop many spires like improbable hats, protecting the softer stone beneath and allowing the columns to stand long enough to earn their fantastical shapes. Where caps fall, hoodoos soon follow—proof that this is a living, changing landscape, not a static monument.
Light is the final sculptor. At sunrise, the amphitheatres ignite, each spire rimmed with gold. By midday, the forms sharpen and flatten, revealing the intricate fluting etched into their sides.
As evening approaches, shadows flood the basins, pooling between the towers until the hoodoos seem to float, suspended in a sea of dusk. From above, those shadows trace the park’s hidden architecture, mapping the slow choreography of erosion.

THE GREAT FINGER FIASCO: HERMANN AND CUVIER
![]() |
| Johann Hermann's Pterodactylus, 1800 |
It began, as many great scientific mix-ups do, with an enthusiastic man, a misplaced fossil, and a few patriotic misunderstandings.
Back in March of 1800, Johann Hermann — a German-slash-French scientist (depending on which invading army was in town that week) — became convinced that an odd fossil described by Collini held the key to something extraordinary.
Without actually seeing the specimen, Hermann took a bold scientific leap: he announced that the animal used its absurdly long fourth finger to support a wing membrane.
This, in hindsight, was rather brilliant — and also rather lucky. Hermann mailed off a letter (and a sketch) to the great French naturalist Georges Cuvier, suggesting that the fossil might even have been war booty, plundered by Napoleon’s scientifically curious troops and whisked off to Paris. After all, France’s armies were busily collecting everything from priceless art to interesting bones at the time — science’s version of a clearance sale.
In his letter, Hermann proposed that this mysterious creature was a mammal. Yes, a furry, bat-like, possibly adorable flying thing. He imagined it with soft pelage, wings stretching elegantly from its fourth finger to its ankle, and a fashionable membrane connecting neck to wrist — the very portrait of prehistoric glamour.
Cuvier, intrigued and perhaps unwilling to admit he didn’t have the fossil in question, agreed with the wing idea but drew the line at “fuzzy mammal.” In December 1800, he published a short note, adopting Hermann’s winged interpretation but firmly declaring, “Non, monsieur — this thing is definitely a reptile.”
Meanwhile, the fossil — allegedly stolen, possibly missing, and definitely not in Paris — turned up safe and sound in Munich. It had been spared confiscation thanks to one Baron von Moll, who managed to secure an “exemption from French enthusiasm.”
By 1809, Cuvier revisited the mystery, producing a longer and more confident description. He called it Petro-Dactyle (a typo he later fixed to Ptéro-Dactyle), thereby cementing both his reputation and a new spelling headache for future generations of palaeontologists.
He also took the time to dunk on his colleague Johann Friedrich Blumenbach, who had suggested the fossil might belong to a shore bird. Cuvier’s rebuttal was deliciously dry:
“It is not possible to doubt that the long finger served to support a membrane that, by lengthening the anterior extremity of this animal, formed a good wing.”
And with that, science had its first flying reptile — a creature born not only from stone but from a glorious mix of imagination, rivalry, and a few well-placed postal misunderstandings.
If you ever feel unqualified to make a bold scientific claim, remember Johann Hermann — who identified a whole new order of life without even seeing the fossil. Sometimes, a good guess (and a long finger) can take you far as history shows here in the The Great Finger Fiasco: How Johann Hermann and Georges Cuvier Accidentally Invented the Flying Reptile.

GRACEFUL BEAUTY: ALBERTONIA
Belonging to a group of extinct bony fishes remarkable for their enamel-coated, diamond-shaped ganoid scales, Albertonia offers a rare and intimate glimpse into life shortly after the end-Permian mass extinction, when marine ecosystems were slowly rebuilding themselves.
Specimens of Albertonia have been discovered in two significant rock units: the Sulphur Mountain Formation near Wapiti Lake in British Columbia and the Lower Triassic Montney Formation of Alberta.
These formations preserve an extraordinary record of Early Triassic marine life—ecosystems shaped by fluctuating sea levels, restricted basins, and the evolutionary experimentation that followed Earth’s most profound biological crisis.
The Sulphur Mountain Formation, in particular, is renowned for its exceptional vertebrate fossils, including fishes, marine reptiles, and rare soft-tissue impressions. Within these beds, Albertonia appears as a slender, streamlined fish with surprisingly tall dorsal and anal fins—features that give it that distinctive “sail-like” profile. These fins likely played a role in stabilization and maneuverability, allowing it to dart through the shallow carbonate-siliciclastic seas with speed and precision.
Ganoid fishes like Albertonia are characterized by their thick, lustrous scales, locking together like a natural chainmail. These scales not only protected the fish from predators but also provide paleontologists with exquisite fossil details. In well-preserved specimens, you can sometimes see the subtle ornamentation—ridges, pits, and patterns—etched into the ganoine coating, each reflecting the biology of a world more than 245 million years removed from our own.
Though Albertonia is long extinct, its fossils help illuminate the pivotal evolutionary story that unfolded during the Early Triassic. As life clawed its way back from catastrophe, species like this little ganoid fish were among the pioneers of new ecological niches, their presence a quiet testament to resilience in ancient oceans.

SCIENCE AND SHENANIGANS: PACIFIC NORTHWEST BEARS
They’re curious, clever, deeply maternal, occasionally cranky, and—much like your favourite mischievous cousin at a family reunion—always two steps from either a cuddle or a wrestling match.
Bear play looks adorable from afar—soft paws swatting, roly-poly wrestling, mock charges that end in huffing and zoomies—but make no mistake: this is serious business.
For young black bears and grizzlies, play is the curriculum of survival.
Wrestling hones strength and coordination. Chase games build stamina and teach cubs how to gauge speed and momentum in uneven terrain.You will recognize the mouthing and pawing in bears if you have ever watched dogs playfighting. It has that same feel but with a much bigger smack.
Even the classic “stand up and paw slap” routine teaches social cues, dominance negotiation, and how to not get clobbered during adult interactions later on.
Adults play too—usually in the brief windows when food is plentiful, neighbours are tolerable, and no one is watching who might judge them for being goofballs.Scientists have documented adult grizzlies sliding down snow patches on their backs and black bears engaging in curious-object play, poking logs, tossing salmon carcasses, and investigating anything that smells even remotely like an adventure.
Interactions between bears are a delicate dance of dominance, tolerance, and opportunism.
Adult females tend to keep to themselves, especially when raising cubs, while males roam wider territories and have higher tolerance thresholds—at least until another big male wanders too close to a prime feeding spot.
During salmon runs, though, everything changes. Suddenly you’ll see a whole cast of characters congregate along rivers: veteran matriarchs who fish with surgical precision, rowdy subadults who think stealth means “splash loudly until the fish give up,” and massive males who square off in dominance displays worthy of a heavyweight title card.
Most conflicts end with bluff charges, raised hackles, and guttural woofs, but real fights—when they happen—are fast, violent, and rarely forgotten by the loser.
![]() |
| Maternal Tenderness: Mamma & Cub |
Cubs are born in winter dens, impossibly tiny—around 300 to 500 grams—and almost hairless, little squeaking marshmallows who depend entirely on their mother’s warmth and fat reserves.
Over the next 18–30 months, a mother teaches her young everything: which plants won’t poison you, how to find grubs by the sound of a rotting stump, how to climb fast when trouble arrives, and how to read the moods of other bears.
Her tenderness is matched only by her ferocity. A mother bear defending cubs is one of the most formidable forces in the forest, and even adult males—three times her size—think twice before pushing their luck.
Where Bears Appear in the Fossil Record
Bears are relative newcomers in deep time, with the earliest ursoids emerging in the late Eocene, around 38 million years ago. True bears (family Ursidae) appear in the early Miocene, and by the Pliocene and Pleistocene, the Pacific Northwest was home to a rich lineup of ursids, including the mighty Arctodus simus, the short-faced bear—one of the largest terrestrial carnivores to ever live in North America.
Black bears show up in the fossil record around the mid-Pleistocene, with fossils found in caves and river-cut sediments from British Columbia down to California. Grizzly bears, originally a Eurasian species, crossed the Bering land bridge during the Pleistocene, leaving their remains in Late Pleistocene deposits from Alaska through western Canada.
Today, the Pacific Northwest remains a stronghold for bears:
Black bears are the most numerous, with an estimated 25,000–35,000 individuals in British Columbia alone, and healthy populations throughout Washington, Oregon, and Idaho. They’re adaptable, omnivorous, and just clever enough to defeat most human attempts at bear-proofing.
Grizzly bears (coastal and interior populations) are far fewer. British Columbia hosts an estimated 13,000–15,000, though distribution varies greatly.
Coastal bears—brown bear or spirit bears—are more numerous and enjoy a salmon-rich in diet, while interior grizzlies face more fragmented landscapes and higher conflict pressures. In the Lower 48, grizzlies number around 2,000, clustered mainly in the Greater Yellowstone and Northern Continental Divide ecosystems.
Conservation efforts, especially Indigenous-led stewardship across the Great Bear Rainforest and interior plateaus, continue to shape recovery, resilience, and coexistence strategies for both species.

CHENGJIANG: A WINDOW INTO THE DAWN OF LIFE
![]() |
| Maotianshania cylindrica |
This is Chengjiang, a UNESCO World Heritage Site and one of the most important early Cambrian Lagerstätten on the planet.
Here, at the base of the Maotianshan shales, paleontologists have uncovered a moment of evolutionary ignition: the rapid diversification of complex animal life known as the Cambrian Explosion.
The Geological Setting: Maotianshan Shales
The Chengjiang fossil exposures occur within the Yu’anshan Member of the Heilinpu Formation, deposited in a quiet, offshore marine environment during the Cambrian.
These fine-grained mudstones accumulated under low-oxygen conditions—an essential factor that inhibited decay and burrowing, allowing soft tissues to fossilize with remarkable fidelity.
Key geological features:
- Age: ~518–520 Ma
- Depositional environment: Distal, oxygen-poor shelf
- Sediment: Fine mudstones and shales ideal for preserving delicate structures
- Taphonomy: Rapid burial via storm-induced sediment flows, sealing organisms beneath thin laminae
It is this marriage of rapid burial and anoxic bottom waters that created one of Earth’s rare Konservat-Lagerstätten, preserving not only bones and shells but organs, musculature, and entire life assemblages.

It’s an impressive welcome—one that sets the tone for the rest of the visit. I wandered first into the Fossil Marine Reptile Gallery, where ichthyosaurs and plesiosaurs stretched out in long, elegant arcs along the walls.
There’s something grounding about standing beside creatures that ruled the seas millions of years before humans took their first steps.
From there, I couldn’t resist the Dinosaur Gallery. Stegosaurus—one of the most complete specimens of its kind—is a standout, and I paused for a while to take in the armour plates and that iconic spiked tail.
Nearby, familiar favourites like Triceratops and Corythosaurus anchor the room, drawing steady streams of families and wide-eyed kids.
The Earth Galleries offered a completely different kind of magic.
Gemstones glittered under soft lights, meteorites sat quietly in their cases, and huge crystals seemed almost unreal in their clarity. Each display felt like a reminder of how beautiful and varied our planet really is.
I ended my visit in the Darwin Centre, where rows of preserved specimens and interactive exhibits gave a glimpse into the research happening behind the scenes.It’s easy to forget that the museum isn’t just a place to display the natural world—it’s an active hub for studying it.
By the time I left, I’d only scratched the surface, but that’s the best part. The museum is the kind of place you can return to again and again, always finding something new tucked into its halls.
I returned at three different times in a week to catch the galleries at various times of day to see the natural light hitting the displays, especially in the marine reptile gallery, so I could take in all the wonderful details.

FROM LAND TO SEA: SEALS
Though we often see them today basking on beaches or popping their heads above the waves, their journey through the fossil record reveals a dramatic tale of land-to-sea adaptation and ancient global wanderings.
Seals belong to a group of marine mammals called pinnipeds, which also includes sea lions and walruses.
All pinnipeds share a common ancestry with terrestrial carnivores, and their closest living relatives today are bears and mustelids (like otters and weasels).
While it may seem unlikely, their ancestors walked on land before evolving to thrive in marine environments. It takes many adaptations for life at sea and these lovelies have adapted well.
The fossil record suggests that pinnipeds first emerged during the Oligocene, around 33 to 23 million years ago.
These early proto-seals likely lived along coastal environments, where they gradually adapted to life in the water. Over time, their limbs transformed into flippers, their bodies streamlined, and their reliance on the sea for food and movement became complete.
In Kwak'wala, the language of the Kwakwaka'wakw First Nations of the Pacific Northwest, seals are known as migwat, and fur seals are referred to as xa'wa.

WHEN CROCODILES WENT ROGUE: VOAY ROBUSTUS
![]() |
| Voay robustus |
Here, until a few thousand years ago, lived Voay robustus, the so-called “horned crocodile.”
Imagine your average Nile crocodile, Crocodylus niloticus, then give it a set of knobby horns just above the eyes, a chunkier skull, and a personality that can best be described as “aggressively misunderstood.”
Voay robustus was no dainty island reptile. This was a serious piece of croc engineering—up to 5 metres long and built like it had something to prove. Its very name says it all: “Voay” (from the Malagasy word for crocodile) and “robustus,” because apparently scientists looked at it and thought, “yes, that’s the robust one.”
The first thing to know about Voay is that it was one of the last survivors of Madagascar’s lost megafauna. While lemurs were still the size of gorillas and elephant birds stomped through the underbrush like feathered tanks, Voay robustus lurked in rivers and swamps, waiting patiently for something—anything—to make a poor life choice near the water’s edge.
For decades, Voay was a bit of a taxonomic mystery. When first described in the 19th century, some thought it might be a close cousin of the Nile crocodile, others insisted it was something entirely different. Scientists bickered, skulls were compared, and Latin names were flung around like darts at a pub quiz.
Then, in 2021, the DNA finally weighed in. Using ancient genetic material from subfossil skulls, researchers revealed that Voay robustus wasn’t a Nile crocodile at all—it was actually the closest known relative of the modern Crocodylus lineage, having split off around 25 million years ago. That makes it something like the evolutionary cousin who shows up at family reunions wearing leather, talking about their motorcycle, and asking everyone if they’ve “still gone soft.”
The Horned Enigma — The most distinctive feature of Voay robustus was its skull—particularly those raised, bony “horns” above its eyes. They weren’t true horns, of course, but enlarged ridges of bone, possibly used for species recognition, intimidation, or just looking fabulous. If you’ve ever seen a crocodile and thought, “You know what that needs? More attitude,” Voay had you covered.
Palaeontologists still debate whether those horns meant Voay was more territorial, more aggressive, or simply had a flair for drama. In any case, it must have been a striking sight.
Picture it: the sun setting over a Malagasy river, the water rippling slightly as a pair of horned eyes rise from below. Birds go silent. A lemur freezes. Somewhere, a herpetologist gets very, very excited.
Madagascar is known for being a biological experiment that got out of hand. Cut off from Africa for around 160 million years, the island evolved its own cast of peculiar creatures: giant lemurs, pygmy hippos, and flightless birds the size of small Volkswagens. Into this mix slithered and splashed Voay robustus, likely arriving during a period of low sea levels that made crossings from the mainland possible.
Once there, Voay probably established itself at the top of the food chain—and stayed there. Anything coming down to drink was fair game. Lemur, bird, hippo, or careless human ancestor—Voay didn’t discriminate. It’s hard to imagine anything else on the island telling a 5-metre crocodile what it could or couldn’t eat.
And yet, despite being a literal apex predator, Voay robustus didn’t make it to the present day. The species vanished roughly 1,200 years ago, right around the time humans arrived in Madagascar. Coincidence? Probably not.
When Humans Moved In — The timeline tells a familiar story. People reach the island about 2,000 years ago. Within a millennium, the megafauna are gone. The giant lemurs disappear, the elephant birds vanish, and the horned crocodile—perhaps hunted, perhaps losing habitat—slips into extinction.
You might imagine that Voay robustus was at least a little resentful about this turn of events. After all, it had survived millions of years of climate swings, sea-level changes, and evolutionary curveballs. And then along came humans, with their spears, boats, and general knack for ecological chaos.
It’s even been suggested that early Malagasy legends of giant crocodiles or river spirits might echo distant memories of encounters with Voay. Which, frankly, would make sense. If a horned, five-metre reptile lunged at your canoe one evening, you’d probably tell stories about it for generations, too.
Genetically, Voay robustus offers a fascinating window into crocodile evolution. While modern Crocodylus species are found across Africa, Asia, the Americas, and Australia, Voay sat just outside that global radiation. In other words, it was part of the evolutionary stem group that gave rise to today’s true crocodiles—but it stayed put while its cousins spread out and diversified.
That makes Voay something of a living fossil that outstayed its welcome—Madagascar’s own reminder of an older, meaner age. Its extinction left the island without any native crocodiles, though Nile crocodiles have since colonised parts of the west coast, re-establishing the ancient reptilian grin on Malagasy soil.
Today, Voay robustus lives on in subfossil bones, DNA samples, and the collective imagination of herpetologists who still dream of rediscovering one lurking somewhere in a forgotten swamp. (They won’t, of course—but it’s nice to dream.)
If anything, Voay reminds us that evolution loves a good experiment, especially on islands. Give a crocodile a few million years in isolation, and it might just decide it wants horns.
And if there’s a moral here—besides “don’t go swimming in prehistoric Madagascar”—it’s that even the fiercest, most robust of creatures can vanish when the world around them changes. So here’s to Voay robustus: horned, hulking, and gone too soon.

HERMIT CRAB: REAL ESTATE TYCOONS OF THE FORESHORE
His body is a soft, squishy spiral that he eases into the perfect size shell time and time again as he grows.
His first choice is always the empty shell of a marine snail but will get inventive in a pinch — nuts, wood, serpulid worm tubes, aluminium cans or wee plastic caps.
They are inventive, polite and patient.
You see, a hermit crabs' desire for the perfect bit of real estate will have them queueing beside larger shells — shells too large for them — to wait upon a big hermit crab to come along, discard the perfect home and slip into their new curved abode. This is all done in an orderly fashion with the hermit crabs all lined up, biggest to smallest to see who best fits the newly available shell.
There are over 800 species of hermit crab — decapod crustaceans of the superfamily Paguroidea. Their lineage dates back to the Jurassic, 200 million years ago.
Their soft squishy, weakly calcified bodies do not fossilize all that often but when they do the specimens are spectacular. Think of all the species of molluscs these lovelies have had a chance to try on — including ammonites — and all the shells that were never buried in sediment to become fossils because they were harvested as homes.
On the shores of British Columbia, Canada, the hermit crab I come across most often is the Grainyhand hermit crab, Pagurus granosimanus.These wee fellows have tell-tale orange-brown antennae and olive green legs speckled with blue or white dots.
In the Kwak̓wala language of the Kwakwaka'wakw, speakers of Kwak'wala, of the Pacific Northwest, a shell is known as x̱ala̱'is and gugwis means house on the beach.
I do not know the Kwak’wala word for a hermit crab, so I will think of these cuties as x̱ala̱'is gugwis — envisioning them finding the perfect sized shell on the surf worn shores of Tsax̱is, Fort Rupert, Vancouver Island.

BANFF NATIONAL PARK, CANADA
Flying above it, you see the Rockies as the early surveyors must have: raw, immense, and defiantly ancient.
The town of Banff itself began humbly in the 1880s, growing from a railway stop on the new transcontinental line into Canada’s first national park. Railroad workers stumbled upon the Cave and Basin hot springs, sparking a cascade of interest in the area’s geology, wildlife, and deep-time history.
That same geology would soon draw paleontologists into the region’s wild backcountry. Just west of Banff, high on a ridge in Yoho National Park, lies the legendary Burgess Shale—one of the most important fossil sites on Earth.
Discovered in 1909 by Charles Doolittle Walcott of the Smithsonian, the Burgess Shale preserves exquisitely detailed soft-bodied creatures from over 500 million years ago, offering a rare window into early animal evolution.
Banff became the nearest hub—its hotels, trails, and later its research community supporting generations of scientists, students, and fossil-hungry adventurers heading into the high passes.
Seen from the sky today, Banff is a quiet modern town nestled among mountains that have been sculpted for hundreds of millions of years. Its story—of hot springs, railways, and extraordinary fossils—is always a delight to explore nestled in Canada's glorious Rockies.
