The next strongest bite comes from the modern saltwater crocodile, Crocodylus porosus, which has a bite force of 1.6 tons. Little was known at the time about the animals that lived in the area during the age the ground sloth was alive. And the research team realized that in 2019, they were "ready to know who killed this ground sloth," Salas-Gismondi said. The researchers haven't ruled out the possibility that the bite marks occurred shortly after death as the Purussaurus dismembered the sloth's carcass. The birds didn't have teeth and the bite marks from marsupial teeth don't match those on the bone.
