Researchers recently uncovered the biggest mass extinction event since the dinosaurs. About 19 million years ago, the shark population was decimated by roughly 90 percent. Up until that point, sharks ruled the ocean. Researchers figured this out by analyzing over a thousand fossilized shark skins.

Elizabeth Sibert is the study’s lead author and a Hutchinson Postdoctoral Fellow at the Yale Institute for Biospheric Sciences at Yale University. Her research is focused on better understanding marine ecosystems from the past, present and future.
