Jefferson's Ground Sloth
(Megalonyx jeffersonii)
 
Residents of Virginia during the Ice Age, these ground sloths became extinct around 9,000 years ago.  They survive nowhere on earth today.  They may have looked somewhat like bears, but their closest living relatives are tree sloths, armadillos, and anteaters.

Giant sloths were huge, bulky, slow-moving herbivores (plant eaters), eating leaves and twigs of woody plants. They were about 20 feet (6 m) long and weighed roughly 3-4 tons. Although other species of sloths still exist in South America, they are much smaller than the giant sloth, which went extinct about 11,000 years ago.
