Mastodon wiki:
>This article is about the prehistoric elephant. For other uses of the word see Mastodon (disambiguation) Mastodons or Mastodonts are members of an extinct genus Mammut of the order Proboscidea; they resembled, but were distinct from, the wooly mammoth.The American mastodon (Mammut americanum) lived in North America. They first appeared almost four million years ago and became extinct approximately 10,000 years ago. They were furry, and had a height of about three meters. They differed from mammoths primarily in the blunt, conical shape of their teeth [1], which were more suited to chewing leaves than to grazing; the name mastodon (or mastodont) means mastoid teeth (Greek μαÏÏá½¹Ï and á½Î´Î¿á½»Ï, "nipple tooth"), and is also an obsolete name for their genus.
