The Cenozoic is divided into three periods: the Paleogene, Neogene, and Quaternary; and seven epochs: the Paleocene, Eocene, Oligocene, Miocene, Pliocene, Pleistocene, and Holocene. The Quaternary Period was officially recognised by the International Commission on Stratigraphy in June 2009. [9]
The Quaternary Period is divided into two epochs: the Pleistocene (2.58 million years ago to 11.7 thousand years ago) and the Holocene (11.7 thousand years ago to today); a proposed third epoch, the Anthropocene, was rejected in 2024 by IUGS, the governing body of the ICS.
Cenozoic Era, third of the major eras of Earth ’s history, beginning about 66 million years ago and extending to the present. It was the interval of time during which the continents assumed their modern configuration and geographic positions and during which Earth’s flora and fauna evolved toward those of the present.

The Cenozoic Era is the most recent of the three major subdivisions of animal history. The other two are the Mesozoic and Paleozoic Eras. The Cenozoic spans only about 65 million years, from the end of the Cretaceous Period and the extinction of non-avian dinosaurs to the present.
Holocene Epoch, younger of the two formally recognized epochs that constitute the Quaternary Period and the latest interval of geologic time, covering approximately the last 11,700 years of Earth’s history.
The Holocene or Recent Epoch is a chronostratigraphic division, the equivalent of a series, the actual lithostratigraphic sequence of rocks, following the Pleistocene Epoch. It is the second of two epochs that make up the Quaternary Period (and its rock sequence, the system).
