Sarcopterygii

Clade of lobe-finned fish

Sarcopterygii (from Ancient Greek σάρξ (sárx) 'flesh' and πτέρυξ (ptérux) 'wing, fin') is a clade (traditionally a class or subclass) of vertebrate animals which includes a group of bony fishes and all four legged land animals, including humans. The common name for this clade is lobe-finned fish. Lobe-finned fish have muscular limb buds (lobes) within their fins, which are supported by appendicular skeletons.
