The Cenozoic era (the era of new life) began 65 million years ago and continues to the present day. It is subdivided into tertiary and quaternary periods.
Angiosperms flourish. The variety of flowers and fruits of flowering plants has led to a wide variety of insects that feed on them.
The fruits of plants and numerous insects have expanded the food supply for birds. Birds became the dominant class of the Cenozoic era.
Mammals became the second dominant class. By the beginning of the era, they were represented by insectivores. Further, mammals began to specialize to different ecological niches, and modern orders appeared.
Some mammals master the aquatic environment. Cetaceans and pinnipeds appear.
In the Quaternary period, primates and humans appear.
