About Coronosaurus
What it was like
Coronosaurus was a horned plant eater about 5 meters (16 feet) long, related to Centrosaurus. The top of its frill carried a cluster of small, twisted spikes, like a crown. Its brow horns varied between individuals.

It lived in the Late Cretaceous in what is now Alberta, Canada. Its bones come from the Oldman Formation, where it shared the land with the tyrannosaur Daspletosaurus.
How it was found
It was first named as a species of Centrosaurus. Ryan and colleagues gave it its own genus in 2012. It is known from two bonebeds with many individuals.
