Geology Scientists pretty much agree that the Cretaceous extinction was due to a climate change. The Paleocene was different climatically from the Mesozoic. For one, it was more temperate around the globe. For two, it was a lot colder near the poles. Continental drift had slowed down greatly since the Mesozoic, and large seas dissapeared off of the continents. Animal Life Mammals diversified and expanded a lot during this Epoch. One of them was Glyptodon, a mammal oddity that evolved in South America. In the seas, sea urchins evolved. Plant Life Flowering Plants whooshed to become the major plant of the Cenozoic. Cycads and other Mesozoic plants declined rapidly.	Glyptodon
	Flowering Plants were abundant in the Paleocene.
