''Gladioserratus'' is an extinct genus of cow shark. It contains three species:〔(【引用サイトリンク】title=''Gladioserratus'' )〕 *''Gladioserratus aptiensis'' Pictet, 1865 *''Gladioserratus magnus'' Underwood, Goswami, Prasad, Verma & Flynn, 2011 *''Gladioserratus dentatus'' Guinot, Cappetta & Adnet, 2014 The authors of its description considered it to be an exclusively Cretaceous genus, containing species living from Hauterivian to Cenomanian.〔 Subsequently the species ''G. dentatus'' was described from the Valanginian of France.〔 Teeth described by Adolfssen and Ward (2015), collected from the middle Danian Faxe Formation at Faxe, Denmark, extend the temporal range of the genus to Paleocene; according to the authors, the species ''"Notorynchus" serratissimus'' Agassiz (1843) should probably be assigned to the genus ''Gladioserratus'' as well, which, if confirmed, would further extended the temporal range of the genus to the early Eocene. ==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「Gladioserratus」の詳細全文を読む スポンサード リンク
