The diversity of modern vertebrates was shaped in partby mass extinctions. The most severe extinction eventwe know of occured at the border between the Permianand Triassic periods about 250 million years ago. Anestimated 96 percent of the marine species and 70 percentof land species disappeared in what is sometimes called“The Great Dying.” The cause of this mass extinctionremains under investigation. Suggested causes includean asteroid impact, extreme volcanic activity, or a sudden release of carbon dioxide from deposits on the sea floor. Which groups of vertebrates were present when this mass extinction event occurred? Which evolvedafterward?
