The origin and early diversification of tetrapods
@article{Ahlberg1994TheOA, title={The origin and early diversification of tetrapods}, author={Per Erik Ahlberg and Andrew R C Milner}, journal={Nature}, year={1994}, volume={368}, pages={507-514} }
A series of new fossil discoveries, coupled with cladistic analysis of old and new data, is beginning to resolve the origin of tetrapods into a documented sequence of character acquisition. Devonian tetrapods were more fish-like than believed previously, whereas Lower Carboniferous tetrapod faunas contain early representatives of the amphibian and amniote lineages. These very different assemblages are separated by a 20-million-year Tournaisian gap' which has yielded very few tetrapod fossils.

A recent review by Rosen et al. (1981) claims that Dipnoi (lungfish) are the sister‐group of the Tetrapoda, that Osteolepiformes is a non‐taxon and that Eusthenopteron is more distant from tetrapods than are Dip noi, coelacanths and probably the fossil Porole piformes, are refuted by use of the same cladistic technique.
