}}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] Cladogram from Swartz, 2012:[2] {{clade| style=font-size:85%;line-height:85%|1={{clade |1=Megalichthyiformes |label2=Eotetrapodiformes |2={{clade |1=Tinirau |2={{clade |1=Platycephalichthys |label2=Elpistostegalia |2={{clade |1=Panderichthys |label2=Stegocephalia |2={{clade |1={{clade |1=Tiktaalik |2=Elpistostege}} |2={{clade |1=Elginerpeton |2={{clade |1=Ventastega |2={{clade |1=Acanthostega |2={{clade |1=Ichthyostega |2={{clade |1=Whatcheeriidae |2={{clade |1=Colosteidae |2={{clade |1=Crassigyrinus |2={{clade |1=Baphetidae |2=Tetrapoda }} }} }} }} }} }} }} }} }} }} }} }} }} }} References1. ^{{cite book |last=Coates |first=M.I. |author2=Friedman, M. |year=2010 |chapter=Litoptychus bryanti and characteristics of stem tetrapod neurocrania |title=Morphology, Phylogeny and Paleobiogeography of Fossil Fishes |editors=Elliot, D.K.; Maisey, J.G.; Yu, X.; and Miao, D. |publisher=Pfeil |isbn=978-3-89937-122-2 |pages=389–416}} {{paleo-lobefinned-fish-stub}}2. ^{{cite journal | last = Swartz | first = B. | year = 2012 | title = A marine stem-tetrapod from the Devonian of Western North America | journal = PLoS ONE | pmid = 22448265 | volume = 7 | issue = 3 | pmc = 3308997 | pages = e33683 | doi = 10.1371/journal.pone.0033683 | url = http://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.0033683;jsessionid=E4E007B3FAC50B3B0C7C2B8B0CBE3F83 | format = | accessdate = }} 1 : Eotetrapodiforms |
