Embrithopoda : ウィキペディア英語版 | Embrithopoda
Embrithopoda ("heavy-footed") is an order of extinct mammals known from Asia, Africa and eastern Europe. Most of the embrithopod genera are known exclusively from jaws and teeth dated from the late Paleocene to the late Eocene, but the order is best known from its terminal member, the elephantine ''Arsinoitherium''. ==Description== While embrithopods bore a superficial resemblance to rhinoceroses, their horns had bony cores covered in keratinized skin and were not made of hair. Not all embrithopods possessed horns, either. Despite their appearance, they were related to elephants, not perissodactyls. The Embrithopoda are tethytheres〔. Retrieved March 2013.〕 and are also believed to be part of the clade Afrotheria. Fossils of embrithopods, such as ''Arsinoitherium'', have been found in Egypt, Mongolia, Turkey, Romania, Namibia and Tunisia. Until the 1970s, only ''Arsinoitherium'' itself was known, appearing isolated in the fossil record.〔
