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.

Relationships

The cladogram presented below is based on studies compiled by Philippe Janvier and others for the Tree of Life Web Project,^[3] Mikko's Phylogeny Archive^[4] and Swartz 2012.^[5]
