b) The Neogene - Existed between 23.03 to 2.6 million years ago

c) The Quaternary – Started some 2.6 million years ago and is continuing till present

The Paleogene is subdivided into three epochs –

A) The Paleocene – existed between 65.5 to 55.8 million years ago

B) The Eocene – existed between 55.8 to 33.9 million years ago and
