Paleozoic
The Paleozoic Era is a major division of the geologic timescale, one of four geologic eras. The Paleozoic includes six geologic periods; from oldest to youngest -- the Cambrian, Ordovician, Silurian, Devonian, Carboniferous and Permian. It extended from roughly 542 MYA to roughly 251 MYA (ICS, 2004). It follows the Precambrian Era and is followed by the Mesozoic Era.
