Rich fossil site

The fossil was unearthed in Dinosaur National Park in Canada, a rich site for Cretaceous Era fossils

First impression

The team first noticed the edge of the frill sticking out of the ground. When they investigated further, they realized it was a tiny ceratopsid, just about 5-feet long.

Mostly intact

The skeleton was mostly intact, with just the front limbs missing. Because of its excellent preservation, the team believes the toddler dino drowned in a stream and was quickly buried in sediments, where it remained undisturbed for millions of years.

Chasmosaurus

The dino likely was a chasmosaurus.

The new discovery will allow the researchers to better understand how the horned dinosaurs grew over time.
