Era & period
Tracy Feng
The information the geologic scale provides is animals and fossils over time and periods. Major divisions of time is called eras.
Four eras. that is Cenozoic,mesozoic,paleozoic and precambrian
The geologic time scale that represents the longest time span is the eon. It is a unit of time that is equal to a billion years.

Precambrian Time extends from 4.6 billion years ago to 540million years ago. that's the greatest expanse of geologic time.

The Precambrian
precambrian times
Precambrian is the largest division of the geologic time scale.
The full list of Eras would be Eoarchean, Paleoarchean, Mesoarchaean, Neoarchaean, Paleoproterozoic, Mesoproterozoic, Neoproterozoic, Paleozoic, Mesozoic, and Cenozoic. Everything prior to the last three are sometimes informally lumped together as "Precambrian".
The divisions of the geologic time scale are divided into four eras. from earliest to closer to the present is the Precambrian, Paleozoic, Mesozoic, Cenozoic. During these time periods, there were several major evolutionary events. Most commonly known are the dinosaurs and humans. Hope that helped :)
It is 4 billion years
