    • n mastodon An extinct proboscidean quadruped of the family Elephantidæ and subfamily Mastodontinæ. Several genera and rather numerous species have been discovered in Tertiary deposits of most parts of the world, in some cases associated with those of the mammoth. One of the largest and best-known of these is the American Mastodon giganteus, which survived to a late Pleistocene period. A specimen nearly perfect was found in Missouri in 1840; it is now in the British museum, and its dimensions are—extreme length 20 feet 2 inches; height 9 feet 6¼ inches; cranium, length 3⅓ feet, width 2 feet 11 inches; tusks, extreme length 7 feet 2 inches, circumference at base 27 inches.

    • n mastodon [capitalized] The typical genus of Mastodontinæ, formerly held to include all the mastodons, now restricted to those of the tetralophodont series, such as M. avernensis of Europe.
