Ocnotherium

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]
