Apr 27, 2023 · The Cenozoic Era is the "Age of Mammals." North America’s characteristic landscapes began to develop during the Cenozoic. Birds and mammals rose in prominence after the extinction of giant reptiles. Common Cenozoic fossils include cat-like carnivores and early horses, as well as ice age woolly mammoths. The Pleistocene Ice Ages began about 2. ... The Cenozoic Era was initially referred to as the third and fourth periods. These two periods are still called the Tertiary and Quaternary. The Quaternary period is composed of our present epoch (the Holocene) and the Pleistocene. The Tertiary is divided into five epochs – Pliocene, Miocene, Oligocene, Eocene and Paleocene.Often called the age of mammals, the Cenozoic includes everything after the K-T extinction event that killed all the non-avian dinosaurs. Beginning 65 million years ago, the Cenozoic’s first of 7 (or possibly 8) epochs was the Paleocene (66-56 Ma).

Geologically speaking, these are recent things that happened, so it became a motif while naming Cenozoic epochs. There used to be only two periods in the Cenozoic: Tertiary and the Quaternary, but Tertiary was split up into Paleogene and …The Paleocene epoch began approximately 65 MYA and ended about 54 MYA. It is the most poorly understood epoch of the Cenozoic era, as it is the time period with the fewest fossils to represent it. However, this epoch is considered important to primate evolution because it offers the first unequivocal record of the earliest primates.Quaternary, in the geologic history of Earth, a unit of time within the Cenozoic Era, beginning 2,588,000 years ago and continuing to the present day.
