Mammut americanum


Mastodon Although the American mastodon was a relative of the prehistoric mammoths, there were considerable differences between the two animals. The two major differences were the animals' sizes and their teeth. The mastodons at Rancho La Brea were roughly half the size of the mammoths and stood about eight feet tall. Although the American mastodon had the same number of teeth throughout their normal lifetime as mammoths, they had more teeth in the jaw at any one time. The mastodon's simple and low crowned teeth indicate that this animal had the diet of a browser, an animal that tends to eat leaves and twigs.

Foot Note!
Grazer vs. Browser: Scientists can usually tell the primary diets of animals by looking at their teeth. The mammoth's tooth on the left is typical for a grazer, an herbivore that eats grasses. The tall plates of which the tooth is formed act as grinding stones and chew grasses in the same way a cow does. In comparison, the ridges on the mastodon's teeth on the right are lower, typical of a browser, a herbivore that eats softer vegetation, such as twigs and leaves.
