Prehistoric Era

A dinosaur from the Prehistoric Era.[1]

The prehistoric era was a period in Earth's past that was so long ago, it predated all or most forms of historical documentation, at least as far as it was known. During the early portions of this time, the human race didn't even exist yet.

Because this era went unrecorded, much of this period was unknown to many who lived afterward, and because of that, people who studied this period had to use different forms of study, since nothing written was known to exist from that time.

The types of studies made were the studies of cave paintings, paleontology, geology, anthropology, archeology and a number of other studies.

Due to these studies, a number of things have been learned of this era, such as the periods known as the Hadean, Mesozoic age and the Pleistocene.
