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. africanum (Hendey, 1972) †A. extant bears .

Sorkin (2006) inferred that the development of the muscle on Agriotherium africanum and Arctodus simus imply an adaptation for ingesting a large amount of plant material, as in the case of living Tremarctos. A well-preserved, almost 16 centimeter - long left upper canine of the scimitar-toothed machairodont Homotherium crenatidens was found at the Milia 1 site that exhibits typical coarsely crenulated edges. your own Pins on Pinterest Time period: Serravalian of the … Though its teeth do not show adaptations for a carnivorous diet, isotope evidence suggests it did eat a significant amount of animal material, similar to some populations of modern brown bears. It is not certain how this force was used by the living animal; a study designed to determine how the genus fed discovered that among living bears, the lowest bite force belongs to the predatory polar bear, which feeds largely on blubber, and the highest bite force belongs to the giant panda, a herbivore which uses it to crush bamboo.

I think mean body mass difference betwenn the cavy and Agriotherium, even such larger species as A. africanum was not that huge, in fact, one reliable shoulder height estimate for A. africanum based on well preserved cranial and postcranial material from South Africa puts it at about 1.3m while some cave bears were tremendous in size as well. 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.
