Lobe-finned fishes and allies
Lobe-finned fishes (Sarcopterygii) contain the coelacanths, the lungfish and various other extinct groups. This class of fish was ancestral to all of the four-legged vertebrates: amphibians, reptiles, birds and mammals. The bones of the pelvis, shoulder girdle and fins of lobe-finned fishes resembles a primitive, limb-like structure.
