    Dinosaurs and Canada

    Dinosaurs were a group of animals that dominated the land environments of every continent. They lived from the late Triassic period to the end of the Cretaceous period (225 to 65 million years ago). However, birds are the direct descendants of dinosaurs, meaning dinosaurs are still common today. Paleontologists have found at least 88 different species of dinosaurs in Canada (see also Dinosaurs Found in Canada). The primary site of these fossils is Dinosaur Provincial Park, Alberta. Well-known dinosaurs first named from Canadian specimens include Albertosaurus, Centrosaurus, Corythosaurus, Dromaeosaurus,Gorgosaurus, Lambeosaurus, Pachyrhinosaurus, Parasaurolophu sand Styracosaurus.
