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]
Based on fossil trackways and the anatomy of its inner ear, which is considerably different from living sloths and more similar to those of armadillos, species of Megatherium, while probably not capable of moving at considerable speed due to limitations of their skeletal anatomy, were likely significantly more agile and mobile than living ...
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.
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
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]
But new discoveries suggest that “humans were existing alongside these animals for at least 10,000 years, without making them go extinct." Some of the most tantalizing clues come from an archaeological site in central Brazil, called Santa Elina, where bones of giant ground sloths show signs of being manipulated by humans.
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.

By Matthew Stock BOURNEMOUTH, England (Reuters) - Scientists have uncovered evidence of ancient humans engaged in a deadly face-off with a giant sloth, showing for the first time how our ancestors ...
