classic favorites like T- rex and Triceratops
The Cretaceous period lasted an incredible 79 million years from 145 to 66 million years ago when an asteroid hit the planet causing a sudden mass extinction that killed off more than 3/4 of all life. Birds made it through this global catastrophe, the direct heirs of the giant non avian dinosaurs. This pattern celebrates the great diversity of the dinosaurs. It includes some of the classic favorites like Tyrannosaurs rex, Triceratops Spinosaurus, Parasaurolophus, Ankylosaurus and more. Perfect wallpaper for paleo nerds of all ages!
