Megatherium

Megatherium (/mɛɡəˈθɪəriəm/ meg-ə-THEER-ee-əm from the Greek mega [μέγας], meaning "great", and therion [θηρίον], "beast") was a genus of elephant-sized ground sloths endemic to South America that lived from the Early Pliocene through the end of the Pleistocene. Its size was exceeded by only a few other land mammals, including mammoths and Paraceratherium.
