Osteolepidida are a group of prehistoric lobe-finned fishes which appears first time during the Devonian period. The order contains five families: Canowindridae, Elpistostegidae, Megalichthyidae, Osteolepidae and Tristichopteridae. The superorder is generally considered to be paraphyletic because the characters that define it are mainly attributes of stem tetrapodomorphs. Below is a cladogram showing the paraphyly of Osteolepiformes compiled and modified from Ahlberg and Johanson (1998).〔 See also Swartz 2012. The Osteolepiformes are marked by the green bracket. |2= |2= |2=''Platycephalichthys'' |bar2=green }} |2=''Jarvikina'' |bar2=green }} |2=''Eusthenopteron'' |bar2=green |3=''Tristichopterus'' |barend3=green }} |2= }} }} }} }} }} }} }} }} }} }} ==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「Osteolepidida」の詳細全文を読む スポンサード リンク
