Epochs of the cenozoic era

The Paleogene is subdivided into three epochs: the Paleocene (65.5 to 55.8 million years ago), the Eocene (55.8 to 33.9 million years ago), and the Oligocene (33.9 to 23.03 million years ago). The Neogene is subdivided into two epochs: the Miocene (23.03 to 5.332 million years ago) and Pliocene (5.332 to 2.588 million years ago).* Stratigraphy

The transition from a warm “greenhouse” to a colder “icehouse” world at ∼34 million years (Ma) ago, followed by stepwise global climatic cooling at ∼14, ∼8, and ∼2.7 and ∼1.2 Ma [1] is the most prominent feature of the Earth’s climatic evolution during the Cenozoic era (0–65 Ma). These climate shifts ultimately shaped the modern … ….

Feb 28, 2020 · Following the Mesozoic era was the Cenozoic, which began about 66 million years ago. This period is also known as the "Age of Mammals," as large mammals, following the extinction of the dinosaurs, became the dominant creatures on the planet.
