They had been extinct on the mainland of North and South America for 10,000 years or more. The term "ground sloth" is used as a reference for all extinct sloths because of the large size of the earliest forms discovered, as opposed to the extant "tree sloths." However, this is a historical convention and does not imply that all extinct sloths were strictly terrestrial in nature. The bulk of ground sloth...
