The Giant Ground Sloths: The giant ground sloth is believed to have weighed about 2.5 tonnes, the same as an Asian Elephant! Their fossils have been found from Patagonia to Alaska. The last ground sloths seem to have died out about 10,000 years ago. Saw this skeleton in the National Museum of Natural History in Washington DC when I was a kid. Must see!!!
Giant Ground Sloth - Megatherium was one of the largest land mammals known, weighing up to 4 tonnes and measuring 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…
The Megatherium was a giant ground sloth found in South America during the Pliocene. It weighed up to four tons and was twenty feet (6m) in length from head to tail. Although it primarily moved on four legs, footprints show that it was capable of being bipedal, in order to reach leaves from the tallest trees. It seemed to be a scavenger and was also one of the last giant Ice Age mammals to disappear. Their remains appear in the fossil record as recently as the Holocene.
