    Time periods of Earth history.

           Below is a list of the commonly used eras that are used to identify differing stages in the planet Earth’s history.‭ ‬While this list has been updated to be as accurate as possible,‭ ‬it should be born in mind that some of these dates are considered approximate and may vary by a few hundred thousand years either way.‭ ‬In addition to this,‭ ‬as new techniques are utilised,‭ ‬studies are conducted and our understanding increases,‭ ‬then these temporal boundaries may in the future be redefined and altered to how they appear below.‭ ‬In addition to this,‭ ‬alternative names for some of these periods are also sometimes used,‭ ‬but these below are the most universally common.
