Among archosaurs, Pterodactyloidea and Rhamphorhynchoidea are commonly used 
as suborders of Pterosauria. This suffix confusion prompted me to alter the 
names to Pterodactyloidia and Rhamphorhynchoidia: an easy change I would 
recommend to be followed wherever the problem arises in zoological 
nomenclature of suprafamilial taxa.
