Ground sloths are a diverse group of extinct sloths in the mammalian superorder Xenarthra. They varied widely in size with the largest, belonging to genera Lestodon, Eremotherium and Megatherium, being around the size of elephants. Ground sloths represent a paraphyletic group, as living tree sloths are thought to have evolved from ground sloth ...
Mylodontidae is a family of extinct South American and North American ground sloths within the suborder Folivora of order Pilosa, living from around 23 million years ago (Mya) to 11,000 years ago. [2]
Mylodon is an extinct genus of ground sloth belonging to the family Mylodontidae, known from southern South America.With a total length of 3 to 4 m and a body mass of 1-2 tonnes, it is one of the largest mylodontids (though it was considerably exceeded in size by the mylodontid Lestodon).
Sloths are almost helpless on the ground but are able to swim. [4] The shaggy coat has grooved hair that is host to symbiotic green algae which camouflage the animal in the trees and provide it nutrients. The algae also nourish sloth moths, some species of which exist solely on sloths. [5]
Although N. shastensis was one of the smallest mainland ground sloth species, it still reached 2.75 metres (9.0 ft) from snout to tail tip and weighed 250 kilograms (551 lb) [8] (one-quarter of a tonne) – much smaller than some of its contemporary species such as the Eremotherium, which could easily weigh over two tonnes and be 6 metres (20 ft) long.

Simomylodon is an extinct genus of ground sloths from the family Mylodontidae. It lived from the Late Miocene to the Middle Pliocene of what is now Bolivia and Argentina, 5.3 to 2.8 million years ago. The most important find material comes from the central Altiplano in Bolivia and includes several skulls and dentition remains. Thus, the so far ...

Megalocnus ("great sloth" in Greek) is a genus of extinct ground sloths that were native to Cuba during the Pleistocene and Holocene epochs. They were among the largest of the Caribbean sloths (Megalocnidae), with individuals estimated to have weighed up to 270 kg (595 lbs) [1] to 200 kg (440 lbs), around the size of a black bear when alive.
