Megatherium ("Great Beast") was a genus of elephant-sized ground sloths endemic to Central America and South America that lived from the Pliocene through Pleistocene existing approximately 5.3 million years. Its size was exceeded by only a few other land mammals, including mammoths and the even larger Paraceratherium.
Megatherium was one of the largest mammals known, weighing up to eight tons, about as much as an African bull elephant. Although it was primarily a quadruped, its footprints show that it was capable of assuming a bipedal stance. When it stood on its hind legs it was aboutt 6 m tall, twice the height of an elephant. This sloth, like a modern anteater, walked on the sides of its feet because its claws prevented it from putting them flat on the ground. Megatherium species were members of the abundant Pleistocene megafauna, large mammals that lived during the Pleistocene epoch.
Shirou's History Fact
The largest sloth ever recorded in history. It stood up on two legs with its long and thick tail used as a support. It then used the claws on its front arms to grab onto branches, allowing it to grab and eat leaves from trees with it long tongue. It's normally docile and slow, but will attack any enemies that approach its young with its claws. It is said that these became extinct due to humans hunting them.
