That was explained to Efe by Tito Aureliano, a researcher at the University Federal of Pernambuco (Ufpe) and coauthor of the study "Morphometry, Bite Strength and Paleobiology of the Caiman Purussaurus Brasiliensis of the Late Miocene," which details the physiology of the land animal with the deadliest bite ever.

Long sharp teeth helped Purussaurus eat the 46 kilos (100 pounds) of meat it needed to nourish itself every day by enabling it to bite through the tou
