Oct 5, 2021 · Geologic Time Scale. 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. We would like to show you a description here but the site won’t allow us.Periods of the Cenozoic Era. Paleogene Period (66 to 23.03 mya) Neogene Period (23.03 to 2.58 mya) Quaternary Period (2.58 mya to present day) The Cenozoic is the era in which we currently live. It was preceded by the Cretaceous-Paleogene Extinction Event of 66 mya.The word cenozoic derives from the Greek words meaning “recent life.”.
