Anisognathous
Definition
Having jaws that are unequal in width, shape, or anatomical structure; characteristic of vertebrate animals whose upper jaw is wider than the lower jaw or vice versa, preventing perfect vertical tooth occlusion. This structural phenomenon is common in many herbivorous mammals (such as equines and ruminants), representing an evolutionary adaptation that facilitates lateral grinding movements necessary for effectively crushing tough plant fibers.
