The extinction at the end of the Paleozoic was the largest recorded in the fossil record. Theories abound as to why this extinction occurred. The world was irrevocably changed after this event, which marked the end of many characteristically Paleozoic lineages. This category is for sites specifically dealing with this extinction.
