Eocene

Phanerozoic

The second epoch of the Paleogene period, spanning 56 million to 33.9 million years ago. It opened with a sharp global warming spike, the Paleocene-Eocene Thermal Maximum, and saw the diversification of early modern mammal groups before a long term cooling trend set in toward its end.

The Paleogene Period (IPA: PAY-lee-ə-jeen, -⁠lee-oh-, PAL-ee-; also spelled Palaeogene or Palæogene) is a geologic period and system that spans 43 million years from the end of the Cretaceous Period 66 Ma (million years ago) to the beginning of the Neogene Period 23.04 Ma.

Lead paragraph
Quote, Lead paragraph
The end is set at a major extinction event called the Grande Coupure (the "Great Break" in continuity) or the Eocene-Oligocene extinction event, which may be related to the impact of one or more large bolides in Siberia and in what is now Chesapeake Bay.
