Their closest relatives were the North American short-faced bears of genus Arctodus They had longer legs and shorter faces than other bears, and were more lightly built. Their ancestors migrated from North America to South America during the Great American Interchange, following the formation of the Isthmus of Panama. Members of the American genera Arctodus and Arctotherium occupied extreme positive RW2 scores in the cranial view because of their expanded medial epicondyle, although in caudal view they overlapped with Ursus species (Fig. The article followed Merriam and Stock (1925) for measurements. His great size alone would have been enough to displace predators from their kills. Arctodus Simus Compared To A Human (Author: Dantheman9758 cc by-s.a. 3.0) This is one prehistoric bear species that was large enough to possibly rival Arctotherium Angustidens. *Agriotherium africanum – primitive short-faced bear – roughly 1400 pounds.

This bear is distinguished from the lesser short-faced bear (Arctodus pristinus) by larger size; bigger, broader, more crowded teeth; a shorter face and relatively longer legs. Ice Age campers had to hang their food higher than campers do today. The species described are all thought to have been larger than any living species of bear. The large width of the jaws in relation to their shortness, plus the huge insertions for biting muscles, gave this bear a vise-like killing bite and the ability to crush bones to obtain marrow.

Archeologists estimate most giant short-faced bears, including females, to weigh 1600 to 1900 pounds. Arctotherium ulna has a total length of 570mm. There is no room for anyone’s opinion on this, because the size of these animals is well known. 2a, b). Although the early history of Arctodus is poorly known, it evidently became widespread in North America by the Kansan age (about 800,000 years ago). It was assigned to Tremarctinae by Krause et al. The South American giant short-faced bear roamed its namesake continent about 500,000 to 2 million years ago and would have been the largest and most powerful meat-eater on land at the time, scientists say. Roman Uchytel’s galleries constitute the first resource solely dedicated to the reconstruction of prehistoric animals beyond the dinosaurs.

They probably scavenged and preyed upon large herbivores such as bison, muskoxen, deer, caribou, horses, and ground sloths. But as more meat-eaters evolved, short-faced bears adapted, becoming smaller and more omnivorous, like the modern-day black bear. It was native to prehistoric North America from about 800,000 years ago, and became extinct about 12,500 years ago. For instance, the South American giant short-faced bear species started huge and became smaller over time, while the North American species grew bigger.
