Megatherium, South America Megatherium was one of the largest land mammals known, weighing up to 4 tonnes and up to 6 m (20 ft) in length from head to tail. It is the largest known ground sloth, as big as modern elephants, and would have only been exceeded in its time by a few species of mammoth. The group is known primarily from its largest species, M. americanum. Megatherium species were members of the abundant Pleistocene megafauna, large mammals that lived during the Pleistocene epoch. They were endemic to Central and South America that lived from the late Pliocene through the end of the Pleistocene. en.wikipedia.org/wiki/Megatherium

Der Mammuth, Elephas primigenius Blumenb. Johann Friedrich Blumenbach gave the woolly mammoth its first scientific name, Elephas primigenius, in 1799 The woolly mammoth (Mammuthus primigenius) was a species of mammoth, the common name for the extinct elephant genus Mammuthus. The woolly mammoth was one of the last in a line of mammoth species, beginning with Mammuthus subplanifrons in the early Pliocene. M. primigenius diverged from the steppe mammoth, M. trogontherii, about 200,000 years ago in eastern Asia. Its closest extant relative is the Asian elephant. en.wikipedia.org/wiki/Woolly_mammoth
