Titanoptera is an extinct order of insects from the Triassic period. Titanopterans were very large in comparison with modern insects, some having wingspans of up to . They were related to modern grasshoppers, but were much larger, with grasping forelegs and elongated mandibles. Another distinctive feature was the presence of prominent fluted regions on the forewings, which may have been used in stridulation. The general shape and anatomy of the Titanopterans suggests that they were predators.〔 ==Classification== Order Titanoptera * Family Mesotitanidae * * Genus ''Mesotitan'' * * Genus ''Mesotitanodes'' * * Genus ''Prototitan'' * * Genus ''Ultratitan'' * Family Paratitanidae * * Genus ''Paratitan'' * Family Gigatitanidae'' * * Genus ''Gigatitan'' * * Genus ''Nanotitan'' * * Genus ''Ootitan'' 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「Titanoptera」の詳細全文を読む スポンサード リンク
