Ground sloths varied widely in size from under 100 kilograms (220 lb) in the Caribbean ground sloths, to 3,700–4,100 kilograms (8,200–9,000 lb) in the largest ground sloth genera Megatherium, Lestodon and Eremotherium. [8] [9] The bodies of ground sloths were generally barrel-shaped, with a broad pelvis. [10]
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 ...
Megalonyx (Greek, "great-claw") is an extinct genus of ground sloths of the family Megalonychidae, native to North America.It evolved during the Pliocene Epoch and became extinct at the end of the Late Pleistocene, living from ~5 million to ~13,000 years ago. [3]
Unfortunately, the bulk of sloth species that once roamed the earth -- some of which grew to be the size of elephants -- cannot say the same. Long ago, there Sloths were once as large as elephants
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.
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.
