翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Crocodylus acer ： ウィキペディア英語版 Crocodylus acer ''"Crocodylus" acer'' is an extinct species of crocodyloid from the Eocene of Utah. A single well preserved skull was described by paleontologist Edward Drinker Cope in 1882 and remains the only known fossil of the species. It was found from the Wasatchian-age Green River Formation. ''"C." acer'' had a long, narrow snout and a low, flattened skull. Some postcranial bones have been attributed to ''"C." acer'' but they have more recently been suggested to belong to the related species ''"C." affinis''. Although they were first placed in the genus ''Crocodylus'', ''"C." acer'' and ''"C." affinis'' are not crocodiles. Recent studies place them as early members of Crocodyloidea, only distantly related to ''Crocodylus''. Although it represents a distinct genus, a generic name has not yet been proposed for ''"C." acer''. ==References== 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「Crocodylus acer」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.
