Giant ground sloths were large, herbivorous mammals that lived during the Pleistocene epoch, around 2.5 million to 10,000 years ago. They could grow up to 13 feet long and weighed over a ton. These creatures roamed the Americas, primarily in regions that are now part of North America and South America. These sloths were closely related to modern sloths but were much larger and had different adaptations. They primarily fed on leaves, fruits, and other vegetation. Fossil evidence suggests that they may have used their strong limbs to dig for roots and tubers, playing a significant role in their ecosystems.
