The Cambrian was the first period of the Paleozoic Era (542-250 million years ago), followed by the Ordovician, Silurian, Devonian, Carboniferous and Permian periods; all of these periods, as well as the succeeding Mesozoic and Cenozoic Eras, were dominated by the vertebrates that first evolved during the Cambrian.At the end of the Paleozoic, about 250 million years ago, as many as 96% of species in the oceans became extinct. They didn’t die all at once. It took over 8 million years for the mass extinction to wipe out all those species. This was the largest mass extinction of all time.
