Osteolepiformes
Osteolepiformes, also known as Osteolepidida, is a group of prehistoric lobe-finned fishes which first appeared during the Devonian period. The order contains five families: Canowindridae, Megalichthyidae, Osteolepidae, Thysanolepidae and Tristichopteridae. The order is generally considered to be paraphyletic because the characters that define it are mainly attributes of stem tetrapodomorphs.[1]
