Mylodon darwini

Mylodon is a genus of extinct ground sloth belonging to the family Mylodontidae, known from the region of Patagonia in Chile and Argentina in southern South America. With a total length of 3 to 4 m, it is one of the best-known and largest representatives of the group. The oldest finds probably date to the Lower Pleistocene. Most of the fossil remains, however, date from the Upper Pleistocene period. One of the most important sites of this phase is the Cueva del Milodón in southern Chile.
