Fig. 191. — Middle Miocene mastodon (Trilophodon productus) beside Upper Pliocene or Lower Pleistocene elephant (E. imperator). Models by Charles R. Knight in the American Museum of Natural History. The imperial elephant is an early arrival. It is by far the largest of these animals, attaining a height of over thirteen feet, and more definitely distinguished by the enormous size of its molar teeth, in which the enamel plates are relatively iew (seventeen), widely separated, and surrounded by a heavy mass of cement. The Columbian elephant is an animal of lesser size, attaining a height of eleven feet, with twenty-one to twenty-two cross ridges in its upper grinders.
