[Jaws of herbivorous mammals].
The jaws of herbivorous mammals are characterized by their large occlusal surface of the molar; high crown of the molar; long snout; etc. However, elephants, the biggest herbivorous mammal, have other characteristics. In the evolutionary trends of proboscidean skulls, concomitant with the increase in tusk size comes on the enlargement, antero-posterior shortening, dorso-ventral elongation of the cranium with increasing cheek teeth size. Naturally, the jaw follows the same evolutionary trends as the cranium.
