Dinosaurs of Canada
Browse Canadian dinosaur records, including Alberta’s horned dinosaurs, hadrosaurs and tyrannosaur relatives, with links to their fossil evidence.
Places, environments and evidence
The Canadian selection brings together Styracosaurus, Corythosaurus, Lambeosaurus, Saurolophus and other western records. Alberta’s fossil formations preserve changing river and coastal-plain environments. Even within one province, profiles can represent different formations and ages; a shared country label is not evidence that all these animals lived together.

Common questions
Is this every dinosaur known from Canada?
No. This is the Canadian subset of the atlas. Museum collections and published studies document additional taxa that do not yet have profiles here.
