Uintatherium (English spelling)

Japanese: ウインタテリウム（英語表記）Uintatherium

An extinct herbivorous mammalian order of slow-footedness that lived in North America during the Eocene epoch of the Paleogene period of the Cenozoic Era. The genus name is derived from the Winta tribe, a native Indian of Utah. It was a bizarre animal that preferred swamps and was about 2 meters tall. The strangest feature was its head, which had three pairs of low, hump-like horns, totaling six, on top of its long, thin head. Its brain was small compared to the size of its head. It had large saber-shaped canines on its upper jaw and an earlobe-like structure on its lower jaw that received the canines. Since the humps and canines were larger in males, it is said that they were secondary sexual characteristics. The tusks were similar to those of a Japanese elephant, and were probably used to jump on and stab enemies. The rest of its body shape was similar to that of modern elephants. It had short limbs and a heavy build. Judging from the shape of its molars, it is thought that it ate soft grass in swamps and marshes.

新生代古第三紀始新世に北アメリカに生息していた草食の絶滅哺乳類の鈍足目。属名はユタ州の先住民族インディアンのウィンタ族にちなむ。湿地を好み，体高約 2mの奇怪な動物であった。最も奇妙なのは頭で，細長い頭の上に，計 6個の低いこぶのような角が 3対あった。頭の大きさのわりに，脳が小さい。上顎に大きなサーベル形の犬歯，下顎に耳たぶのような形のものがあって犬歯を受けていた。こぶと犬歯が雄では大きくなっていたので，第2次性徴ではないかとする説がある。牙はケンシコの牙に似ていて，敵に飛びかかり，いきなり突き刺すのに用いられたと思われる。頭のほかの体つきはいまのゾウに似ている。四肢が短く，体つきは重々しい。臼歯の様子から，沼や湿地で柔らかい草などを食べていたと考えられる。
