An extinct mammal related to the rhinoceros. It was distributed in North America and East Asia in the late Eocene Epoch of the Tertiary Period, and complete skeletons have been found as fossils in Utah and Mongolia. It is a large, sturdy rhinoceros with no horns, and is distinguished from other rhinoceros by its large incisors and canines. Its name Amynodon comes from the Greek amyno meaning "to defend" and odontos meaning "tooth." It is thought to have lived in swamps like the hippopotamus.

絶滅した哺乳動物でサイの仲間。第三紀始新世の後期に北アメリカと東アジアに分布し,ユタ州とモンゴルでは完全な骨格が化石として発見されている。がっしりとした大型のサイで,角はなく,大きな切歯と犬歯をもつことによって他のサイとは区別される。ギリシア語の〈防御する〉という意味のアミュノamynōと〈歯〉を意味するオドントスodontosからアミノドンの名がつけられた。カバのように沼沢地で生活していたと思われる。
