Unit of time into which eras on the Geologic Time Scale are subdivided

(Example Mesozoic Era is subdivided into the Triassic, Jurassic and Cretaceous)

• EONS

• ERAS

• EPOCHS

• PERIOD

 Name for the time in Earth`s early history that accounts for ninety percent of Earth's time, but only cellular organisms lived

• CENOZOIC ERA

• MESOZOIC ERA

• PALEOZOIC ERA

• PRECAMBRIAN

It started with the Cambrian explosion this is a time when a great number of organisms arose. During this time invertebrates developed along with vertebrates like fishes. Later animals began to reach land. Then the carboniferous period began and reptiles developed. Pangea formed and it ended with a mass extinction. This era lasted from 540 million years ago to 245 million years ago.
