The Cenozoic contains three Periods: • Paleogene from ~66 MYA to ~23 MYA • Neogene from ~23 MYA to ~2.6 MYA • Quaternary from ~2.6 MYA to today appearance of humans. Epochs are divisions within a Period. Epochs are very useful for scientists studying organisms. You will see the Cenozoic commonly divided by Epochs, for example, theThe Paleogene Period* is the first of three periods comprising the Cenozoic Era. The Cenozoic, sometimes known as the "Age of Mammals", as the Mesozoic was the "Age of Reptiles", is known by its Epochs. The Paleogene is composed of the first three of these Epochs, (Paleocene, Eocene, and Oligocene Epochs). Four additional Epochs …The Periods and Epochs of the Cenozoic Era. The Paleogene period (65-23 million years ago) was the age when the mammals began their rise to dominance. The Paleogene comprises three separate epochs: * The Paleocene epoch (65-56 million years ago) was fairly quiet in evolutionary terms. This is when the tiny mammals that survived the K/T ...…
