Dinosaurs: The Cretaceous Period

Most of the known dinosaurs lived during the Cretaceous period. The Cretaceous Period lasted from 144 to 65 million years ago. During this time, mammals arrived, flowering plants evolved and changed the landscape. There was a high level of activity (continental plate movement) and volcanic activity.

The Cretaceous period ended 65 million years ago with the extinction of the dinosaurs and many, many other prehistoric life forms.  The Triceratops was the most known dinosaur in that period.
