Ocnotherium is an extinct genus of ground sloth known from the Late Pleistocene of Brazil, belonging to the family Mylodontidae, containing the species Ocnotherium giganteum. It is a member of the subfamily Mylodontinae, but its relationship to other members of that subfamily are uncertain.[1] It had osteoderms embedded within its skin, like some other mylodontids.[2] It was likely a mixed feeder,[3] and may have been adapted to digging.[4]
