Although the American Mastodont hasn't officially been dubbed with more than one subspecies, the Mastodont occupied many habitats and biomes. Its fossils and remains have been found in the La Brea tar pits suggesting that a possible sub-species lived in a grassland/woodland area. Fossil bones have been discovered in the Ozark Mountains of Missouri suggesting another, Mountain species. And also a skull undug in a small town near Toronto, Ontario (a possible boreal/coastal spp.).

Mammoth/Mastodont SegrationEdit

The Wooly Mammoth has been highly popularized and many have heard of it but not the Mastodont, but even among those who know of the mastodont, many people easily mistake the mammoth and mastodont. In they're fossils, its the teeth and tusks that make the difference. Superficially, it is like telling apart grizzly and black bears: The Mammoth has a more upright stance, head held high on the shoulders, and a prominent shoulder hump (like the grizzly bear); The Mastodont has a horizontal stance, lowly-held head, and a shallow to absent hump (like the black bear). The Tusks of The Mastodont are relatively straight, while Mammoth tusks are very curved.


The American Mastodont has had many, many different common names: The Great American Incognitum; Mississipium; Missourium; Jelly's Mammoth; Bear-Mammoth; Pseudelephant; Ohiognitum; Ohio Incognitum; Carnivorous Elephant; Boulder-buster; Nozdrohk (aboriginal); The American Behemoth; Ngymazk (aboriginal); Teatooth; and others.

Also, it has had various scientific nomenclature: Mastodon americanum; Mastodon ozarkensis; Mastodon jellysi; Mastodon giganteus; Elephas mastodontus; Urselephas sp.; and others.

(please note 'Nozdrohk is of russian aborigine origin and probably means 'Mammoth'.)
