What was Earth Like During the Paleocene Epoch?
The Paleocene epoch is the time on Earth between the Cretaceous-Tertitary extinction, 65.5 million years ago, until 55.8 million years ago. Paleocene means “old(er) new” in Greek. This is a reference to the fact that the Paleocene was the beginning of the Era of Mammals, which continues today, but was too primitive to contain modern animal orders.
