CAMBRIAN PERIOD
570-505
Million Years Ago

The Cambrian period of the Paleozoic era was characterized by a diverse eruption of life in the seas. Life had not yet evolved on land. The highest forms of life existing at this time were the trilobites, which reached lengths up to two feet. Green and red algae started to appear as well as sponges, gastropods, and segmented worms.
