Agriotherium africanum was a giant short-faced bear that became extinct five million years ago. A. africanum also had a very powerful bite for its size as indicated by a high BFQ value (Table 1). This is quite simply, the largest bear ever discovered and by default, a contender for the largest carnivorous land mammal ever to live. This long-lived genus persisted from at least ~11.6–2.5 Mya. extant bears . Arctotherium angustodens - South American short-faced bear - roughly 3000 pounds.

The worn condition of the teeth suggests that the bear was an older adult at the time of death. Agriotherium africanum; ursidae; feeding behaviour; finite element analysis; bite force. It had dog-like crushing teeth. administration. [6], Very large size would have been necessary to steal and defend kills in environments dominated by some of the most powerful carnivorous mammals that have ever lived, such as the sabertooth cat Amphimachairodus, with whom it shared territory in both Afro-Eurasia and North America, and the bone-cracking canid Epicyon and the massive feliform sabertooth Barbourofelis, which it lived alongside in Texas, as evidenced by fossil deposits at Coffee Ranch. They had longer legs and shorter faces than other bears, and were more lightly built. Agriotherium measured about 2.7 metres in length, making it larger than most living bears. Their ancestors migrated from North America to South America during the Great American Interchange, following the formation of the Isthmus of Panama. coffeyi (Dalquest, 1986) †A. schneideri (Sellards, 1916), Agriotherium is an extinct genus of bears whose fossils are found in Miocene through Pleistocene-aged strata of North America, Europe, Africa, and Asia.

Although they were powerful in size and able to put up a fight, life was (and often still is) tough in Africa.

By comparing the skulls of several species, scientists also found polar bears to have surprisingly weak bites. africanum (Hendey, 1972) †A. Although our results are consistent with the suggestion that the giant panda is well‐adapted to both generate and resist high bite reaction forces at the molars, they do not support the contention that it is better adapted to resist high reaction forces generated at the molars than at the canines. It also did not show the long claws and increased forelimb strength typical of mammals that dig for food. Tags: sivalensis (Falconer & Cautley, 1836) © 2012 Roman Uchytel.

PaleoDB taxon number: 41303. Many of these fascinating creatures are unfamiliar to the public and remain a mystery even to science. †A. The relatively complete and un-abraded condition of the mandible would preclude long distance stream transport. ursus arctos piscator (beringianus) ursus arctos yesoensis (ursus arctos ferox) ursus arctos lasiotus . Tooth root surface areas serve as proxies for bite force potentials, and by extension, dietary specialization in extant carnivorans. Shortened jaws with high bite forces are found in other mammals like Gelada baboons that eat grasses but evolved from non-grazing ancestors, and in bone-crushing scavengers, like spotted hyenas and borphagine dogs. first time visitors read here. general science. †A. However, this bone measured 48.5cm (19 inches) whereas those of other polar bears of the same age would be at the most 43 cm (17 inches) long. Reconstructions of the carnivore's skull revealed that it was well adapted to resist the forces involved in eating large prey.
