翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Enaliarctos ： ウィキペディア英語版 Enaliarctos ''Enaliarctos''〔From Greek , ''enalios'', of the sea; and , ''arktos'', bear, "referring to the arctoid, including ursid, Carnivora" (Mitchell & Tedford, 1973, p. 218).〕 is an extinct genus of pinniped. Prior to the discovery of ''Puijila'', the five species in the genus ''Enaliarctos'' represented the oldest known pinniped fossils, having been recovered from late Oligocene and early Miocene (ca. 24–22 million years ago) strata of California and Oregon. ==Description== It had a short tail and developed limbs with webbed feet. Unlike modern sea lions, it had a set of slicing carnassials; the presence of slicing teeth (rather than purely piercing teeth as in modern fish-eating pinnipeds) suggests that ''Enaliarctos'' needed to return to shore with prey items in order to masticate and ingest them. Still, ''Enaliarctos'' had some sea lion-like characteristics, such as large eyes, sensitive whiskers, and a specialized inner ear for hearing underwater. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Enaliarctos」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
