- The Tertiary has five principal subdivisions, called epochs, which from oldest to youngest are the Paleocene
(66 million to 55.8 million years ago), Eocene (55.8 million to 33.9 million years ago), Oligocene (33.9 million to 23 million years ago), Miocene (23 million to 5.3 million years ago), and Pliocene (5.3 million to 2.6 million years ago).Paleocene
The Paleocene or Palaeocene, is a geological epoch that lasted from about 66 to 56 million years ago. It is the first epoch of the Paleogene Period in the modern Cenozoic Era. As with many geologic periods, the strata that define the epoch's beginning and end are well identified, but the exact ages remain uncertain.
