The third period was the Cretaceous period when dinosaurs growth has been fully developed. This was the time when some unique dinosaurs were there on the earth. Triceratops, Tyrannosaurus rex, Parasaurolophus, Carnotaurus Anatosaurus, Monoclonius, Tarbosaurus Gallimimus Corythosaurus, Albertosaurus, there were dinosaurs Cretaceous.
