By the end of the extinction, just one genus of these apex creatures survived, but surprisingly, it flourished. Lystrosaurus — a “disaster taxon,” or an organism that thrives in conditions that are lethal for most species — is “the poster child of the end-Permian extinction,” says Pia Viglietti, a paleontologist with the Field Museum of Natural History in Chicago.In a third and final phase of the extinction, the Permian killer returned to stalk the land for another 35,000 years.
