Megatherium was a giant ground sloth that lived during the late Pleistocene epoch, around 2.5 million to 10,000 years ago. This massive creature roamed the grasslands and forests of South America, reaching lengths of up to 20 feet. Unlike modern sloths, Megatherium had strong limbs and a robust body, allowing it to browse on leaves and shrubs. Fossils of Megatherium have been found in various locations, providing insights into its size and lifestyle. It is believed that this enormous sloth was herbivorous, using its large claws to dig up plants. The extinction of Megatherium is thought to be linked to climate change and human activity.
