Cenozoic epochs.

The Cenozoic contains three Periods: • Paleogene from ~66 MYA to ~23 MYA • Neogene from ~23 MYA to ~2.6 MYA • Quaternary from ~2.6 MYA to today appearance of humans. Epochs are divisions within a Period. Epochs are very useful for scientists studying organisms. You will see the Cenozoic commonly divided by Epochs, for example, thePaleocene epoch: (66.0-56.0 million years ago) The Paleocene epoch was the first epoch of the Cenozoic Era. It began with the extinction of the dinosaurs and ended with the rise of the first mammals and birds. Eocene epoch: (56.0-33.9 million years ago) The Eocene epoch was a time of warm, wet climates and lush forests. Mammals diversified ...Each period is further divided into epochs: the Paleogene encompasses the Paleocene, Eocene, and Oligocene epochs; the Neogene comprises the Miocene and Pliocene epochs; and the Quaternary includes the Pleistocene and Holocene epochs. This article provides an overview of the Cenozoic Era and the major events that occurred during its span.Figure 8.1.4 The periods (middle row) and epochs (bottom row) of the Cenozoic era. [Image Description] Most of the boundaries between the periods and epochs of the geological time scale have been fixed on the basis of significant changes in the fossil record.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. The success of Coryphodon, a half-ton plant-eater with a tiny, dinosaur-sized brain, can be inferred by its wide distribution across early Eocene North America and Eurasia.

The term Paleogene was devised in Europe to emphasize the similarity of marine fossils found in rocks of the first three Cenozoic epochs, as opposed to the later fossils of the Neogene Period (23 million to 2.6 million years ago) and the Quaternary Period (2.6 million years ago to the present). Did it rain a lot in the Cretaceous period?

Geologic Time Scale. 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.
