The giant ground sloth or Megatherium is an extinct ground sloth that was endemic to South America during the ice age. They lived from the early Pliocene till the end of the Pleistocene (the great ice age). The term Megatherium contains two Greek elements, méga meaning 'great,' and theríon meaning 'beast.' There are also called megathere. The Megatherium americanum is the best-known elephant size type species of this genus. The Megatherium became an extinct animal around 12,000 years ago. It happened during the extinction event called Quaternary. It was also observed that one of the reasons for the extinction of this genus was hunting. One of the prototypical prehistoric sloths of the genus called Megalonyx (giant claws) was scientifically named Megalonyx jeffersonii after the then Vice President of America, Thomas Jefferson, who examined this genus in 1797. It was in the year 1788 that one of the first fossils specimens of Megatherium was found. Manuel Torres discovered this genus in Argentinian rubber called Luján. There are several families with more than 80 genera of the extinct ground sloth.

The giant ground sloths of the superorder Xenarthra and order Pilosa are an extinct group of sloths. The fossils of these species were recovered from as many as 150 sites in North America. The general disposition and lifestyles of each species varied. These giant sloths were peaceful and would only attack in self-defense. The diet varied as per the climate and these giant sloths were slow-moving, as per research on their fossils.
The giant ground sloths (Megatherium americanum) were of the mammals class of animals.
These ground sloths became extinct around 12,000 years ago.
They (Megatherium americanum) were the occupants of a wide range of South American lightly wooded regions. These giant sloths were native to Pampas. During the Great American interchange, some closely related species of genus Eremotherium occupied the temperate zones of North America. The Megalonyx jeffersonii (ground sloths) species had occupied central and north America. The giant ground sloth skeleton has been found in the far north of Alaska, in Canada, and in New Mexico. The very first discoveries made of Megalonyx jeffersonii fossils were in modern-day West Virginia. The Organ cave in the Greenbrier County, West Virginia had certain bones of M. jeffersonii. They were the members of the Pleistocene megafauna.
These ground sloths were found in woodlands, grasslands, temperate, arid, or semiarid open habitats. They preferred staying in an open region. They also preferred forest and vegetation with water bodies around.
These ground sloths lived in groups.
The average lifespan of these ground sloths is unknown.
The reproduction type of these giant sloths was viviparous. The data on their reproductive cycles are not available. It is impossible to conclude on this topic due to their extinction. It was also found that the adults cared for the young ones.
The conservation status of these animals is Extinct. They became extinct 12,000 years ago, which is known as the last ice age.
These animals had a strong skeleton, big pelvic girdle with a wide muscular tail. They used their tail as a tripod while standing on their hind legs to reach tall trees. While the hind legs were powerful, the forelegs had curved claws to support body weight. They walked on the sides of their feet as they could not place their feet face down due to big claws. It was believed that they waddled on their front knuckles and hind legs. They were traditionally quadruped but they could also walk on two feet. They were hairless like the modern-day elephants. They had cone-shaped mouths with prehensile lips. The megatherium species chewed vertically. These animals had deeper jaws compared to other sloths. Bones called stylohyal and epihyal, which support the tongue were merged. They had a narrow muzzle. The teeth were equally spaced at the back of their mouth. The M. americanum had extremely hypsodont teeth that supported their fibrous diet. The teeth form a V-shaped interlock when viewed from the side.
The sloths of the modern-day make sound to communicate. However, data about the communication techniques of these extinct mammals are not available.
The retrieved fossil of giant ground sloth size was 240 in (6 m) length and 120 in ( 304.8 cm) height. These were the largest species of ground sloths. Among the giant ground sloth size facts is that their size was similar to that of an elephant. The giant ground sloth compared to human size would be much larger.
The giant ground sloths are slow-moving creatures. The exact data on speed is not available.
The weight of these species was 8800 lb (3991.6 kg).
There was no specific name for females or males given to these animals.
There was no specific name given to the baby giant ground sloths.
It is believed that these animals were selective eaters of plant-based food. Giant ground sloth diet facts from research show that they ate a variety of food like hard grasses, the foliage of trees, yucca, and shrubs.
No. These animals are believed to have attacked only if triggered. Sloths usually do not chase or hunt and it is thought that these extinct animals were not different.
No. These creatures would not make a good pet. They are very large in large and have been extinct for thousands of years!
It was first believed that these sloths used their large claws to climb trees, similar to tree sloths. It was later discovered that they used their claws to dig holes.
It is believed that to dig plants, they would first sit on haunches and would tug on the plants with their feet.
These ground sloths were relatives of the living tree sloths, armadillos, and anteaters.
When Thomas Jefferson named one of the giant ground sloths Megalonyx, he was not aware of the fact that animals could go extinct. He also asked the famous Lewis and Clark to keep an eye out for giant ground sloth sightings. There are currently four species of Megalonyx.
Unlike Megatherium, Megalonyx was a medium-sized genus of giant ground sloths. Their hind legs were laid face down on the ground (plantigrade).
These were a few of the big species that were able to swallow avocado whole. So, they are given the credit for dispersing these seeds away from the parent tree.
Research shows various reasons for their extinction. One of the reasons is believed to be hunting for food. It is also believed that they became extinct due to rapid climate change and they failed to adapt. Another theory believes that they contracted a slow-killing disease. Loss of habitat was also shown to be a reason. The evidence of some fossil remains of these species suggests that they died in their own feces.
The giant ground sloths lived around 12,000 years ago. The last descendent of giant ground species disappeared around 4,200 years ago.
