[29] Whether or not ground sloths had a slow metabolism like living xenarthrans (including living sloths) is debated. [19]
In many species of Megatherium, the lower jaw is relatively deep, which served to accommodate the very long hypselodont (evergrowing) teeth, [20] which are considerably proportionally longer than those of other ground sloths. Like other ground sloths, the number of teeth in the jaw is reduced to 5 and 4 teeth in each half of the upper and lower ...
Sloths are a Neotropical group of xenarthran mammals constituting the suborder Folivora, including the extant arboreal tree sloths and extinct terrestrial ground sloths. Noted for their slowness of movement, tree sloths spend most of their lives hanging upside down in the trees of the tropical rainforests of South America and Central America .

Closeup of hand, showing claws Closeup of skull. Megatheriidae is a family of extinct ground sloths that lived from approximately 23 mya—11,000 years ago. [3]Megatheriids appeared during the Late Oligocene (Deseadan in the SALMA classification), some 29 million years ago, in South America.
