Its fossils have been found in France, Belgium, and Maryland. ==Description== ''Eurhinodelphis'' was around in length. In most respects, it would have looked like a modern dolphin or porpoise, but its upper jaw was elongated into a sharp tip similar to that of a swordfish. Most likely, ''Eurhinodelphis'' used it in a similar manner to swordfish, hitting or stabbing prey. It also had long, sharp teeth. Compared with earlier fossil species, ''Eurhinodelphis'' had complex ears, suggesting that it already hunted by echolocation like modern whales. Its brain was also asymmetrical, a trait found in modern dolphins, and possibly associated with the complexities of navigating its environment.〔 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「Eurhinodelphis」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.
