How long was the cenozoic era
You have already learned that the Earth is 4.54 billion years old. The Phanerozoic eon began 541 million years ago (or, 0.541 billion years ago). Paleogene Period, oldest of the three stratigraphic divisions of the Cenozoic Era spanning the interval between 66 million and 23 million years ago. Paleogene is Greek meaning “ancient-born” and includes the Paleocene (Palaeocene) Epoch (66 million to 56 million years ago), the Eocene Epoch (56

Online exhibits : Geologic time scale The Cenozoic Era The Cenozoic Era is the most recent of the three major subdivisions of animal history. The other two are the Mesozoic and Paleozoic Eras. The Cenozoic spans only about 65 million years, from the end of the Cretaceous Period and the extinction of non-avian dinosaurs to the present.The Cenozoic Era, often referred to as the "Age of Mammals," spans from about 66 million years ago to the present day. It is characterized by the proliferation and diversification of mammals, the rise of modern ecosystems, and significant climatic shifts, including the cooling of the Earth and the formation of ice caps in polar regions.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 (23 million to 5.3 million years ago) and the Pliocene (5.3 million to 2.6 million years ago) epochs. The Neogene, which means “new born,” was designated as such ...The Tertiary Period (65 million years ago to 2.6 million years ago) The first period in the Cenozoic Era is called the Tertiary Period. It began directly after the K-T Mass Extinction (the "T" in "K-T" stands for "Tertiary"). At the very beginning of the time period, the climate was much hotter and more humid than our current climate.

Figure 8.8. 1: Paraceratherium, seen in this reconstruction, was a massive (15-20 ton, 15 foot tall) ancestor of rhinos. The Cenozoic, meaning “new life,” is known as the age of mammals because it is in this era that mammals came to be a dominant and large life form, including human ancestors.The Cenozoic witnessed a rapid diversification of life-forms in the ecological niches left vacant by this great terminal Cretaceous extinction (or K–T extinction). In particular, mammals, which had existed for more than 100 million years before the advent of the Cenozoic Era, experienced substantial evolutionary radiation.…
