A large and bizarre animal that inhabited Ohio during the Pleistocene and became extinct at the end was the ground sloth. These ox- sized animals migrated northward from South America during the Ice Age and are occasionally found in bog deposits in Ohio. They had large, strong front legs with claws that were used to obtain vegetation.[[Category:Natural History Geology ]] [[Category:Fossils]]
