Periods in the cenozoic era.

The first period of the Cenozoic Era, called the Tertiary Period, has been divided into the Paleogene and Neogene periods. Most of the Paleogene Period saw birds and small mammals become more diverse and grow greatly in numbers. Primates started to live in trees and some mammals adapted to live part-time in the water.The eras are in turn divisible into periods, epochs and ages.
