Neogene
NEE-oh-jeen
Also Known As Tertiary Historical name for the combined interval now split into the Paleogene and Neogene periods; no longer a formally recognized stratigraphic term.
Phanerozoic
The Neogene is the second period of the Cenozoic Era, spanning about 23.04 to 2.58 million years ago and comprising the Miocene and Pliocene epochs. Mammals and birds remained the dominant terrestrial vertebrates, diversifying into a wide range of forms across expanding grassland habitats, and the first hominins, the ancestors of humans, appeared near the end of the period. The Neogene and the preceding Paleogene were formerly grouped together as the Tertiary Period, a term still in informal use though no longer formally recognized.

Lead section
The Neogene ( NEE-ə-jeen) is a geologic period and system that spans 20.45 million years from the end of the Paleogene Period 23.04 Ma (million years ago) to the beginning of the present Quaternary Period 2.58 Ma.
Flora and fauna (hominins)
The first hominins, the ancestors of humans, appeared near the end of the period.
Lead section
The earlier term Tertiary Period was used to define the span of time now covered by Paleogene and Neogene and, despite no longer being recognized as a formal stratigraphic term, "Tertiary" still sometimes remains in informal use.
Lead paragraph
The global climate cooled considerably throughout the Neogene, culminating in a series of continental glaciations in the Quaternary Period that followed.
