What is Cenozoic in geologic time scale?

The Cenozoic Era. The Cenozoic Era is the most recent of the three major subdivisions of animal history. The other two are the Mesozoic and Paleozoic Eras.

What is unique about the Cenozoic era?

A unique feature of the Cenozoic was the formation of extensive glaciers on the Antarctic continent about 35 million years ago and in the Northern Hemisphere at different points during the Pleistocene Epoch. The vast ice sheets of the latter glaciation event covered large parts of North America and Europe during four periods known as ice ages.

How did the Cenozoic era begin?

The Cenozoic Era started with the extinction of dinosaurs and moved into the age of mammals. This led to the diversification and increase in size of mammals. Chimpanzees began to walk on two legs because they needed to find food sources in the African Savannah. This freed their hands to carve out tools and gain control of fire.
