Fossil of baby dinosaur that waded into fast water and drowned the smallest of its kind

It’s incredibly rare to find a complete skeleton of a baby dinosaur, but that’s just what a team of researchers at the University of Alberta and The Royal Tyrrell Museum did when they found the juvenile fossil of a Chasmosaurus belli, a dinosaur similar to a Triceratops. The find is the smallest ever for dinosaurs of this type.

The team made the find in Dinosaur Provincial Park in southern Alberta.

“The big ones just preserve better: They don’t get eaten, they don’t get destroyed by animals,” Dr. Philip Currie, a paleobiologist at the University of Alberta and research associate at the Tyrrell Museum told Live Science. “You always hope you’re going to find something small and that it will turn out to be a dinosaur.” (Photo: Clive Coy/’Dino Lab’,University of Alberta)

The first remains of Chasmosaurus were found in Alberta, Canada, in 1901. Chasmosaurus had a small horn on its nose and two curving horns on its brow. It had a large but fragile frill, which may have served more as intimidation than as a defense. Fossil evidence suggests this was one of many lies Chasmosaurus lived.

You saw the first draft, now take a look at the full teaser poster for dinostuck's top secret project! Here you see not a bunch of random dinosaurs, but those from the Dinosaur Park fauna. More posters are coming soon so stay tuned!

UPDATE: Added quills to the Stegoceras and gave Chasmosaurus a bit more fluff as per request of raptorcivilization and dinostuck! Thanks for your input!


Herbivorous Dinosaurs from Alberta. By Julius Csotonyi

"About 75 million years ago, shows niche partitioning at work. It is likely that dietary differences between each species allowed the habitat to support such a diverse population of herbivores." Read more at Species New to Science

Chasmosaurus and Deinosuchus, Walter Ferguson

This is an instant, a moment, a breath in the universe’s 13 billion-year life. The Deinosuchus, all mouth and armor, erupts from the lake, its maw a yawn that envelopes graveyards. The lake cracks into white fans under the lashing tail, and the body slides all too easily up the sand onto the shore. The young chasmosaur cowers before the rushing cave of teeth, muscles tensed as adrenaline floods the dinosaur’s systems, buzzes even in its bones. The heart skips a beat; the animal even forgets to breathe. Above, birds’ wings whistle through the Cretaceous air, though the subtle sounds of feathers against breeze are drowned by the splashing and rushing below. The birds, white and fat, are oblivious, but Chasmosaurus is all too aware of this instant, this one juncture of time among countless weres and will bes, a blink that suspends the little dinosaur above that hair-thin line between existence and oblivion.
