Cretaceous Period (7 ago 142000000 ano antes da era comum – 6 ago 65000000 ano antes da era comum)

Descrição:

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.
