The first major Cenozoic glaciation step was the EOT at the end of the Eocene, which we discussed in a preceding part of this review (section 4.1.3.1). The second major glaciation event was the OMB at the end of the Oligocene.This era was between about 250 to 66 million years ago. During this period, life evolved and diversified. It gets its name from the Greek language, which means ‘Middle life.’. This period is also famous as the age of dinosaurs or the age of reptiles. The Mesozoic era existed between the Paleozoic and the Cenozoic era.Neogene Period, the second of three divisions of the Cenozoic Era. The Neogene Period encompasses the interval between 23 million and 2.6 million years ago and includes the Miocene and the Pliocene epochs. Learn more about the Neogene Period in this article.
