Even near their extinction, saber-toothed cats likely had enough to eat, researchers noted. Saber-toothed cats, American lions, woolly mammoths and other giant creatures once roamed across the American landscape. However, at the end of the late Pleistocene about 12,000 years ago, these megafauna went extinct, a die-off called the Quaternary extinction.
