Humans subdivide time into useable units such as our calendar year, months, weeks, and days; geologists also subdivide time. They have created a tool for measuring geologic time, breaking it into useable, understandable segments. For the purposes of geology, the “calendar” is the geologic time scale. It is evident that East Africa experienced three major Late Cenozoic lake periods at 2.7 to 2.5 Ma, 1.9 to 1.7 Ma, and 1.1 to 0.9 Ma.

This warm time is called the Paleocene-Eocene Thermal Maximum and Antarctica and Greenland were ice-free during this time. Since the Eocene, tectonic events during the Cenozoic caused persistent and significant planetary cooling. The Quaternary period is subdivided into the Pleistocene and Holocene epochs. The Holocene epoch began about 11,700 years ago. If the Mesozoic era was the Age of Reptiles, the Cenozoic era is the Age of Mammals.
