Mammoth

"The mammoth (Elephas primigenius)." -Taylor, 1904

"Mammoth is a species of extinct elephant, the fossil remains of which are found in European, Asiatic and North American formations. Geologically speaking, the mammoth or Elephas primigenius, dates from the post-pliocene period, its remains having been frequently found associated with human remains, and its figure carved on bone. It had large curved tusks; was covered with fur and shaggy hair; and was twice as large as the modern elephant. Bones and tusks have been found in great abundance in Siberia, and America. In the St. Petersburg Imperial Museum is the perfect preserved carcass of a mammoth found in the frozen ice in Siberia in 1903."—(Charles Leonard-Stuart, 1911)

"Mastodon is an extinct genus of proboscideans, closely allied to the true elephants. The genus ranged in time from the middle of the Miocene period to the end of the Pliocene in the Old World, when they became extinct. In America several species survived to a late leistocene period.

Mastodons or Mastodonts are members of the extinct genus Mammut of the order Proboscidea and form the family Mammutidae; they resembled, but were distinct from, the woolly mammoth, which belongs to the family Elephantidae. Mastodons were browsers, while mammoths were grazers.

"Megatherium is a genus of extinct edentates, founded on a nearly complete skeleton discovered on the banks of the Lujan, about 9 miles from Buenos Ayres, and sent by the Marquis of Loretto, the viceroy, to the Royal Museum of Madrid. The best-known species was nearly as large as an elephant, though the limbs were shorter. Its mounted skeleton measures 18 feet in length, of which the tail occupies five. Dr. Leidy has described a smaller species from the post-Tertiary of Georgia and South Carolina; and there is a third, founded on remains from Brazil."—(Charles Leonard-Stuart, 1911)
