Cretaceous Period (7 agos 142000000 año aC – 6 agos 65000000 año aC)
Descripción:
This period ended with the most famous mass extinction in history- the one that killed the dinosaurs. At this time, before the dinosaurs' end, it was a nice, warm period with no ice caps at the poles. Much of our dry land - Southern England and the Midwest of the Americas- were underwater at this time.
