The purpose of this paper is to relay information about the Cretaceous Period.
Some are even alive today, while many people do not even notice. Picture in your mind how these huge reptiles might have looked walking, feeding, hunting and fighting. Dinosaurs were reptiles, but not quite as we know them today. The oldest known dinosaur is Eoraptor, a meat-eater that lived million years ago.
There is a concerted effort to reverse engineer a chicken into a dinosaur remember, birds are the descendants of theropod dinosaursbut the team still has a ways to go.
The speediest dinosaurs were an ostrich-like species, such as Dromiceiomimus, which could probably run at speeds of up to 60 kilometres per hour. Temperatures would have dropped dramatically. Dinosaurs started developing after a mass extinction of the Paleozoic Era just about million years ago.
Not all fossils are of the animals themselves.
Are all of the Dinosaurs dead?
