A pair of researchers, Guillaume Guinot and Fabien Condamine, both with Université de Montpellier, in France, has looked at the impact of the Cretaceous–Paleogene (K-Pg) extinction event on elasmobranch species to learn more about survival of marine creatures during extinction events. In their study, published in the journal Science, the marine biologists collected and analyzed data for thousands of fossil species that were living during the Late Cretaceous–Paleocene era.
