The Rhipidistia, also known as dipnotetrapodomorphs (formally Dipnotetrapodomorpha)[1] are a clade of lobe-finned fishes which include the Tetrapods and lungfishes. Rhipidistia formerly referred to a subgroup of Sarcopterygii consisting of the Porolepiformes and Osteolepiformes, a definition that is now obsolete.[2] However as cladistic understanding of the vertebrates has improved over the last few decades a monophyletic Rhipidistia is now understood to include the whole of Tetrapoda and of the extant lungfishes.
