翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Sclerorhynchus ： ウィキペディア英語版 Sclerorhynchus ''Sclerorhynchus'' is an extinct genus of primitive batoidean that lived in the Cretaceous. The namesake of the Mesozoic suborder Sclerorhynchoidea, it is not quite clear whether they were closer to the Rajiformes (skates and rays) or to the Pristiformes (sawfishes). Its fossils have been found mainly around the Mediterranean region. The related ''Ganopristis'' might actually belong in ''Sclerorhynchus''. ''Sclerorhynchus'' was about long, and looked somewhat like a modern sawfish, having a long snout with tooth-like serrations along the sides. In other respects, it looked like a flattened shark with enlarged, wing-like pectoral fins. It probably used these to glide over the ocean floor, propelled by its tail, weeding out shrimps, shellfish and flounders from the sand with its long snout. ==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「Sclerorhynchus」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.
