About Rubeosaurus
What it was like
Rubeosaurus was a horned dinosaur with a straight horn on its nose and long spikes around the edge of its frill.
It was first described as a species of Styracosaurus. Some scientists think it belongs there, or with Stellasaurus, rather than in a genus of its own.
Its world
It lived in the Late Cretaceous in what is now Montana, in the United States. Its bones come from the Two Medicine Formation, where it shared the land with the horned Achelousaurus, the duck-billed Maiasaura and the tyrannosaur Daspletosaurus.
How it was found
McDonald and Horner named Rubeosaurus in 2010. Two finds are known.
