A Playful Encounter in the Cretaceous Seas

The illustration depicts a juvenile Tylosaurus, one of the great marine reptiles of the Late Cretaceous seas, caught in a moment of playful curiosity. Instead of hunting for food, this young mosasaur is simply toying with an ammonite, nudging and circling it in the open water much like a dolphin might play today. This lighter side of prehistoric life reminds us that not every interaction in ancient oceans was a life-or-death struggle. Scenes like this are featured in my upcoming book...

Olorotitan - The "Giant Swan" of the Late Cretaceous

Olorotitan is a fascinating genus of hadrosaurid, or “duck-billed,” dinosaur that lived during the Late Cretaceous period, around 66 million years ago, in what is now eastern Russia. Its name, meaning “giant swan,” reflects its graceful appearance and long, ornate crest. This large herbivore could grow up to 9 meters (30 feet) in length and was distinguished by a unique, hollow, backward-curving cranial crest, likely used for visual display and sound resonance. Olorotitan had a robust...

Small but Mighty - Nemicolopterus in the Cretaceous Forests

Imagine a creature no larger than a sparrow, yet capable of gliding effortlessly through the dense forests of the Early Cretaceous, this was Nemicolopterus, one of the tiniest pterosaurs ever discovered. With a wingspan of just under 12 inches, it relied on speed, agility, and keen eyesight to snatch insects and avoid predators.

Found in China’s Liaoning Province, Nemicolopterus reminds us that in the ancient world, size didn’t limit survival, sometimes, the smalle...

Hamipterus - Fisher of Ancient Skies

The skies of the Early Cretaceous were home to Hamipterus, a spectacular pterosaur that soared over what is now the deserts of northwestern China. With a wingspan stretching up to 4 meters, it was a master of both flight and fishing, its long, slender jaws bristling with interlocking teeth perfect for snaring slippery prey. Fossil beds have revealed something extraordinary about this animal: entire colonies of Hamipterus preserved alongside hundreds of delicate eggs, suggest...

Maiasaura - The Good Mother of the Cretaceous

Maiasaura, the “good mother lizard,” was a gentle, plant-eating hadrosaur that roamed the Late Cretaceous plains of what is now Montana. Famous for its remarkable nesting sites, Maiasaura cared for its young long after they hatched, returning to the same colony grounds year after year, evidence of social bonds and complex behavior in dinosaurs. With its duck-bill snout, strong legs and ability to walk on two or four legs, it was well-adapted to grazing on a variety of vegetation.

A Moment of Prehistoric Tenderness

High atop a rugged Cretaceous cliffside, with waves crashing far below, a devoted pterosaur returns to its precariously perched nest. The wind tugs at its membranous wings as it gently lowers its long beak, offering a small lizard to a chirping hatchling nestled in a tangle of twigs and leaves. This remote coastal ledge, unreachable by most predators, serves as a safe haven for this ancient flier to raise its young.

In my upcoming book, Snapshots of Prehistory, you'll discover ...

Tropeognathus: The Sky Cleaver of the Cretaceous

Tropeognathus was a giant pterosaur that ruled the skies during the Early Cretaceous. With a wingspan reaching up to 8 meters, it was one of the largest flying animals to ever exist. Its name means "keel jaw," a reference to the long snout with a sharp crest on top and bottom. This jaw was lined with pointed teeth, perfect for grabbing slippery fish from the ocean below.

It may have skimmed the waves with its beak or snatched prey in midair. Its hollow bones made it light, while its mas...

Repenomamus - The Dinosaur-Eating Mammal

Repenomamus was no ordinary Mesozoic mammal, it shattered the age-old image of early mammals as timid, shrew-sized insectivores hiding in the shadows of dinosaurs. Living around 125 million years ago in what is now China, Repenomamus grew to the size of a modern-day badger, making it one of the largest known mammals of its time. But what truly stunned paleontologists was the discovery of dinosaur bones inside the fossilized stomach of one individual, evidence that it fed on ...

Leptostomia - Chopsticks for a Beak!

With jaws as long and slender as chopsticks, Leptostomia was a Cretaceous oddity, a pterosaur that evolved to probe deep into soft mud, snatching burrowing invertebrates hidden beneath the surface. Its elongated beak was finely tuned for precision, acting more like surgical tweezers than a traditional pecking bill. Paleontologists believe this flying reptile may have stalked coastal flats and riverbanks, silently sweeping its head in search of prey, much like a modern-day curlew…on...

Stegoceras - The Helmeted Herbivore

Stegoceras was a small, dome-headed dinosaur that roamed the forests of Late Cretaceous North America. Roughly the size of a large dog, this herbivorous pachycephalosaur is best known for its thick, rounded skull, which may have been used in head-butting contests much like modern-day rams. With its stiff tail for balance and sharp eyesight, Stegoceras likely navigated dense vegetation with ease, feeding on soft plants and fruit.

Ornithopods at Night!

Under the pale glow of the moon, two Jurassic ornithopods move quietly through a dry forest. The air still radiates the heat of the dry season, but the night offers a temporary relief. They’ve chosen to travel under the cover of darkness, safer than braving the scorching sun, though not without its own dangers.

Each step is cautious, their senses alert. The rustle of leaves, the crack of a twig, every sound could signal a lurking predator. But thirst drives them forward. Somewhere ahe...
