Ctenochasma (meaning "comb jaw") is a genus of Late Jurassic ctenochasmatid pterosaur belonging to the suborder Pterodactyloidea.[5] A single specimen, consisting of a partial skull with complete brain case, was found in France and housed in the collections of the Saint-Dizier Museum.[7] Ctenochasma is distinguished mainly by its numerous (over 400 in adults) long, thin, curved and closely packed teeth, which lined its elongated and narrow snout.Instead, the spatulate profile formed by the teeth probably indicate a spoonbill-like lifestyle, increasing the surface area of the jaws in order to catch small prey.In the analysis, they recovered Ctenochasma within the family Ctenochasmatidae, more precisely within the subfamily Ctenochasmatinae, sister taxon to the tribe Pterodaustrini.
