Era, a very long span of geological time; in formal usage, the second longest portion of geologic time after an eon. Ten eras are recognized by the International Union of Geological Sciences. An era is composed of one or more geological periods. The stratigraphic, or rock, term that corresponds to ‘era’ is ‘erathem.’.The Quaternary ( / kwəˈtɜːrnəri, ˈkwɒtərnɛri / kwə-TUR-nə-ree, KWOT-ər-nerr-ee) is the current and most recent of the three periods of the Cenozoic Era in the geologic time scale of the International Commission on Stratigraphy (ICS). [4] It follows the Neogene Period and spans from 2.58 million years ago to the present. [5]The Precambrian includes approximately 90% of geologic time.
