Eotetrapodiformes is a clade of sarcopterygian fish including tetrapods (four-limbed vertebrates) and their immediate ancestors, two groups of stem tetrapods called tristichopterids and elpistostegalids. Eotetrapodiformes is part of the larger clade Tetrapodomorpha, but exclude the basalmost tetrapodomorphs, such as osteolepiforms.[1]
