How would you describe the Cenozoic era?
The most recent period of the Earth's history.

The sequence of the eras of Earth's history from oldest to most recent is: Precambrian, Paleozoic, Mesozoic, and Cenozoic. The Precambrian era comprises the earliest stages of Earth's formation, followed by the Paleozoic era known for the rise of complex life forms.
