The Cenozoic is also known as the Age of Mammals because the terrestrial animals that dominated both hemispheres were mammals – the eutherians in the Northern Hemisphere and the metatherians (marsupials, now mainly restricted to Australia and to some extent South America) in the Southern Hemisphere. The extinction of many groups allowed ...

The Mammal Neogene zones or MN zones are system of biostratigraphic zones in the stratigraphic record used to correlate mammal-bearing fossil localities of the Neogene period of Europe. It consists of seventeen consecutive zones (numbered MN 1 through MN 18; MN 7 and 8 have been joined into MN 7/8 zone) defined through reference faunas, well ...
The earliest evidence for life on Earth includes: 3.8 billion-year-old biogenic hematite in a banded iron formation of the Nuvvuagittuq Greenstone Belt in Canada; [30] graphite in 3.7 billion-year-old metasedimentary rocks in western Greenland; [31] and microbial mat fossils in 3.48 billion-year-old sandstone in Western Australia.
c. 23.04 Ma – Neogene Period and Miocene epoch begin; c. 22 Ma – First hyenas. c. 20 Ma – Giraffes and giant anteaters evolve. c. 18–12 Ma – estimated age of the Hominidae/Hylobatidae (great apes vs. gibbons) split. c. 16 Ma – The hippopotamus evolves. c. 15 Ma – First mastodons, bovids, and kangaroos. Australian megafauna diversify.
The Neogene (/ ˈ n iː. ə dʒ iː n / NEE-ə-jeen, [6] [7]) is a geologic period and system that spans 20.45 million years from the end of the Paleogene Period 23.04 million years ago to the beginning of the present Quaternary Period 2.58 million years ago.

A finer subdivision was established by Pierre Mein in 1975, who divided the Neogene in 17 zones, known as the MN zonation, indicated by the letters MN (Mammal Neogene) and a number. Similarly, a more detailed subdivision for the Paleogene period was established. There are 30 such Mammal Paleogene zones (MP1 to MP30, numbered from old to young). [2]
