Tertiary
Tertiary is an officially deprecated but still widely used term for a geologic period from 65 million to 2.6 million years ago, a time span that lies between the superseded Secondary period and the Quaternary. The Tertiary is no longer recognized as a formal unit by the International Commission on Stratigraphy, its traditional span being divided between the Paleogene and Neogene Periods of the Cenozoic Era.
