Cenozoic epochs
Oct 20, 2023 · The Neogene spans the Miocene and Pliocene epochs, and the Quaternary includes the Pleistocene and Holocene epochs. Geologic processes. Cenozoic rocks are extensively developed on all the continents, particularly on lowland plains, as, for example, the Gulf and Atlantic coastal plains of North America. The oldest of the geological eras is the Eoarchean, which began approximately four billion years ago. The majority of the fossil evidence that we have for primate evolution comes from the Cenozoic era—the current geological era, dating from 65 million year ago (MYA) to the present. The Cenozoic era is divided into a series of epochs.The global climate was much warmer during the early Cenozoic than it is today, and equatorial-to-polar thermal gradients were less than half of what they are at present. Which era is divided into periods and epochs? Cenozoic Era The two periods of the Cenozoic Era are the Tertiary and Quaternary. A period is divided into an even smaller unit ...

It can be subdivided into two …The Oligocene epoch is part of the Tertiary Period in the Cenozoic Era, and lasted from about 33.7 to 23.8 million years ago (mya).

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).
