The Proterozoic division of the geologic time scale is an era of the Phanerozoic eon.

Further Explanations:

The Phanerozoic era is the existing geologic eon of the geologic time period. It can also be stated as the era of ample flora and fauna on Earth. It encompasses an eon of about 541 million years and is believed that it began with Cambrian Period when faunas first developed rigid shells preserved as fossil record. About 96% of life form on Earth got streaked out 251 million centuries ago. It was the era of extinction of dinosaurs about 65 million ages ago with the advent of mammals. Earth’s climate had changed several times during the era and during the demise of the Precambrian era, much of the earth was roofed with glaciers. During initial phase of Phanerozoicera, the climate became warm and tropical. Since then Earth's climate went through four cycles of frosty glaciers and warm humid seas.

The Phanerozoic era of noticeable life is being alienated into three major eras on the basis of their characteristic groupings of life-forms, namely the Paleozoic spanned amid 541 million to 252 million years, Mesozoic spanned for 252 million to 66 million years, and lastly the Cenozoic spanning from 66 million years ago till present.
