The dorsal and anal fins of ''C. pinnatiformis'' had very high, narrow crests, and it also had very long, thin pelvic fins. Its fins give it a superficial resemblance to a freshwater angelfish, leading some people to erroneously refer to ''C. pinnatiformis'' as an "angelfish," too. ==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「Ceratoichthys」の詳細全文を読む スポンサード リンク
