It is known exclusively from some preserved skulls. It was originally thought to be a tuna or mackerel, hence the generic name translating as "dawn" or "Eocene tuna." Later, it was reappraised to be a jackfish, related to ''Teratichthys'' and ''Eastmanalepes'' (syn. "''Caranx primaevus''"). ==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「Eothynnus」の詳細全文を読む スポンサード リンク
