Osteolepiformes
Temporal range: 396–299 Ma Middle Devonian to Late CarboniferousOsteolepis. Scientific classification Kingdom: Animalia Phylum: Chordata Subphylum: Vertebrata Class: Sarcopterygii Subclass: Tetrapodomorpha Superorder: Osteolepiformes* Clades Osteolepiformes (or 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.[1]
Below is a cladogram showing the paraphyly of Osteolepiformes modified from Ahlberg and Johanson (1998):[1] The Osteolepiformes are marked by the green bracket.
