翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Pseudopulex ： ウィキペディア英語版 Pseudopulex ''Pseudopulex'' is a genus of extinct, flea-like, parasitic insects that once fed on dinosaurs.〔(【引用サイトリンク】title='Giant flea fed on dinosaur blood like mosquitoes' - NY Daily News )〕 The two species, ''Pseudopulex jurassicus'' and ''Pseudopulex magnus'', are similar to modern fleas, but their bodies were more compressed, and they had longer claws which they used to hold on tightly to dinosaurs or pterosaurs. They were also 10 times as large as modern fleas and possessed serrated stylets, likely for feeding on blood through thick layers of skin. == Discovery == Fossils of ''Pseudopulex jurassicus'' are known from the middle Jurassic-aged Jiulongshan Formation, 165 million years old.〔(【引用サイトリンク】title=Ancient fleas plagued ancient dinosaurs )〕 Fossils of ''Pseudopulex magnus'' are from the Early Cretaceous Yixian Formation, 125 million years old. 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「Pseudopulex」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.
