'''Paleozoic''' means ''ancient life''. Paleozoic era is the earliest of three [[geologic]] eras of the Phanerozoic eon.
There are seven different periods in the Paleozoic era:
*[[Cambrian]]
*[[Ordovician]]
*Silurian
*Devonian
*Mississippian
*Carboniferous
*Permian
The Paleozoic starts shortly after the breakup of a supercontinent called Pannotia and at the end of the era, the continents gathered together into a supercontinent called [[Pangea]] (approximately 300 million years). ''The Paleozoic is bracketed by two of the most important events in the history of animal life. At its beginning, multicelled animals underwent a dramatic "explosion" in diversity, and almost all living animal phyla appeared within a few millions of years. At the other end of the Paleozoic, the largest mass extinction in history wiped out approximately 90% of all marine animal species.'' <ref> [http://www.ucmp.berkeley.edu/paleozoic/paleozoic.html The Paleozoic Era 543 to 248 Million Years Ago]
