Cenozoic era fossils

Cenozoic Era, third of the major eras of Earth's history, beginning about 66 million years ago and extending to the present. It was the interval of time during which the continents assumed their modern configuration and geographic positions and during which Earth's flora and fauna evolved toward those of the present.

Oct 30, 2012 · Salix sp. leaf. Liquidambar sp. seed pod. The 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). Those are Paleocene, Eocene, and Oligocene. The division of periods is quite common in the Cenozoic because it helps us navigate through the most recent changes in the history of life. After the Paleogene comes Neogene, featuring two epochs: the Miocene and the Pliocene. Finally, comes our current period- the Quarternary.Dinosaurs likely lived within the state during the Mesozoic Era; however, no rocks from that era survived here and therefore Ohio lacks dinosaur fossils.
