The Giant Ground Sloth, or Megatherium (Giant Beast) was an omnivorous relative of the modern-day sloth that lived in Pliocene - Pleistocene South America.
Evidence has been found suggesting Giant Sloth's survival into modern times. There is reason to believe indians hunted them. Fresh skin, dung and footprints were discovered in a cave in the Patagonian region of Argentina in 1895. Tales of the native indians revealed that when they tried hunting these creatures with arrows, the arrows bounced off their skin. It has been discovered that Megatherium had a layer of strong, bony armour in its skin, something also seen in the skins found in the cave. There have also been sightings of giant ground sloths in the area. One of the witnesses is Ramon Lista, the governor of Argentina.
