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.
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 Neogene Period is a unit of geologic time starting 23.03 Ma. [10] and ends at 2.588 Ma. The Neogene Period follows the Paleogene Period. The Neogene consists of the Miocene and Pliocene and is followed by the Quaternary Period.
Subdivision of the Neogene Period according to the ICS , as of 2017 [ 1 ] The Late Miocene (also known as Upper Miocene ) is a sub-epoch of the Miocene Epoch made up of two stages .
The Aquitanian Stage was named after the Aquitaine region in France and was introduced in scientific literature by Swiss stratigrapher Karl Mayer-Eymar in 1858.. The base of the Aquitanian (also the base of the Miocene Series and the Neogene System) is defined as the place in the stratigraphic column at the first appearance of foram species Paragloborotalia kugleri, the extinction of ...
During the Pliocene the earth climate system response shifted from a period of high frequency-low amplitude oscillation dominated by the 41,000-year period of Earth's obliquity to one of low-frequency, high-amplitude oscillation dominated by the 100,000-year period of the orbital eccentricity characteristic of the Pleistocene glacial ...

The Burdigalian is, in the geologic timescale, an age or stage in the early Miocene.It spans the time between 20.43 ± 0.05 Ma and 15.97 ± 0.05 Ma (million years ago). ). Preceded by the Aquitanian, the Burdigalian was the first and longest warming period of the Miocene [4] and is succeeded by the L
