The different Epochs in the Cenozoic periods. There are certain subperiods within the Cenozoic era. These subperiods give a more detailed breakdown of how evolution events occurred in this era.

Humans subdivide time into useable units such as our calendar year, months, weeks, and days; geologists also subdivide time. They have created a tool for measuring geologic time, breaking it into useable, understandable segments. For the purposes of geology, the “calendar” is the geologic time scale.Cenozoic epochs are the shortest and from this period all remains provided the best evidence of history and evolution (precisely because they are short) - there was not enough time for them to decay during erosion and other weather disasters because of which the remains stayed.
