The Cenozoic is divided into two periods, the Palaeogene and Neogene , and they are in turn divided into epochs. The Palaeogene consists of the Paleocene , Eocene , and Oligocene epochs, and the Neogene consists of the Miocene , Pliocene , Pleistocene , and Holocene epochs, the last of which is ongoing. Historically, the Cenozoic has been divided into periods (or sub-eras) named the Tertiary (Paleocene to Pliocene) and Quaternary (Pleistocene and Holocene), although most geologists no longer recognize them. LIFE IN THE CENOZOIC ERA The Cenozoic is the age of Mammal s. During the Cenozoic, mammals diverged from a few small, simple, generalized forms into a diverse collection of terrestrial, marine, and flying animals. The Cenozoic is just as much the age of Savanna s, or the age of co-dependent Flowering Plant s and insects. Bird s also evolved substantially in the Cenozoic. Geologically , the Cenozoic is the era when Continent s moved into their current positions. Australia-New Guinea split from Gondwana to drift north and, eventually, abut South-east Asia ; Antarctica moved into its current position over the South Pole ; the Atlantic Ocean widened and, late in the era, South America became attached to North America .
