Ctenochasmatoidea is a group of pterosaurs within the suborder Pterodactyloidea. It was defined by Unwin (2003) as the clade containing Cycnorhamphus suevicus, Pterodaustro guinazui, their most recent common ancestor, and all its descendants.[1] The earliest known ctenochasmatoid remains have been found in the Stonesfield Slate formation (UK), which dates to the Bathonian stage of the Middle Jurassic, dated to about 166 million years ago.[2]

Pereda-Suberbiola et al. (2012) use Fabien Knoll's (2000) definition of Pterodactylidae;[3] Knoll defined Pterodactylidae as a clade containing "Pterodactylus antiquus, Ctenochasma elegans, their most recent common ancestor and all [its] descendants".[4] The analysis conducted by Pereda-Suberbiola et al. (2012) indicated that Ctenochasmatoidea is nested within such defined Pterodactylidae;[3] other analyses, such as Unwin's (2003)[1] make such defined Pterodactylidae nested within Ctenochasmatoidea instead.
