Data from: An early Miocene extinction in pelagic sharks

Elizabeth Sibert & Leah Rubin
Sharks populations have been decimated in recent decades due to over-fishing and other anthropogenic stressors, however the long-term impacts of such changes in marine predator abundance and diversity are poorly constrained. We present evidence for a previously unknown major extinction event in sharks that occurred in the Early Miocene, approximately 19 million years ago (Ma). During this interval, sharks virtually disappeared from open-ocean sediments, declining in abundance by >90%, and morphological diversity by >70%, an...
