Fig. 2.7. Simple diagram showing the application of biomechanical knowledge to inferring the functional morphology of vertebrate skulls.

Carnivorous mammals, such as a cat, tend to have a jaw joint in line with their sharp, shearing teeth, much as the handles of a pair of scissors align with the blades. This puts the best cutting surface towards the back of the jaws. In contrast, herbivorous mammals such as horses have a jaw joint located above the tooth row, allowing their teeth to simultaneously contact one another like a nutcracker.
