{{QuoteBox|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]</ref>}}
