The Paleozoic | ||

The Paleozoic
was a period of nearly 300 million years, stretching from the Cambrian Explosion of life about 542 million years ago to the mass extinctions at the end of the Permian, about 251 million years ago.
Early in the Paleozoic most of the existing phyla of life appeared. During the Paleozoic life moved from the seas out to the land. Much of the world’s supply of coal, oil, and limestone was formed during the Paleozoic.
