Fossils have been found in Monte Bolca. In life, species of ''Ductor'' would have resembled pilot fish, though, they are more closely related to the jackfish. Some experts place ''Ductor'' into its own family, "Ductoridae," while others place the genus within the closely related Carangidae. ==See also== * Prehistoric fish * List of prehistoric bony fish 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「Ductor」の詳細全文を読む スポンサード リンク
