|An Agriotherium africanum skull|
The scans showed that most of the force would have been exerted by the canine teeth, and that there was very little grinding area at the back. This creature would have sliced chunks of meat from its prey, swallowing them whole. The models also showed that the jaw bones of Agriotherium were incredibly strong in comparison to the other specimens; and while the others exhibited high stress points on the joints, Agriotherium was far more resilient and could potentially produce far stronger bites than any other terrestrial mammal today or in prehistory.
Wroe suggests that Agriotherium had a far stronger skull and bite force, as it fed upon a wider variety of prey to get at the nutritious red meat. In contrast, the polar bear possessed the weakest bite force and skull strength out of all of the specimens. Wroe believes that this contrast is because Agriotherium was adapted to feed upon meat, whereas the polar bear has a diet of soft blubbery seals, eating the energy-rich fat as opposed to the tough muscle.
