Megalichthyiformes

Megalichthyiformes is a clade of prehistoric tetrapodomorphs which first appeared during the Devonian period. It was named in 2010 by Michael I. Coates and Matt Friedman, who defined it as a stem-based taxon containing all tetrapodomorphs closer to Megalichthys than to Eusthenopteron.[1]
