Epochs of the cenozoic era

From geology we have an understanding of the time involved in the development of earth. In biological anthropology, we are specifically focused on the late Mesozoic/early Cenozoic eras in relation to primate evolution. You should be familiar with the time ranges for the epochs of the Cenozoic.

The age of mammals, the cenozoic, has been split into seven epochs. Those seven epochs are as follows: Paleocene Eocene Oligocene Miocene Pliocene Pleistocene Holocene Paleocene ~ 65-56 Million Years Ago The comet or meteor hit and the dinosaurs, except the birds, were wiped out roughly 65 million years ago. extinct by the end of this epoch.

It is important to note, however, that all of the periods of the Phanerozoic era are subdivided into the epochs and ages. The Giant Mammals of the Eocene, Oligocene, and Miocene Epochs. The Eocene epoch, from 56 to 34 million years ago, witnessed the first plus-sized herbivorous mammals.
