Gnathosaurus subulatus

The first remains of Gnathosaurus (a jaw fragment) found in the Solnhofen limestones of Bavaria were mistaken with those of a crocodile. This small size pterosaur is characterized by a slender skull comparable to Ctenochasma but with a distinct sagittal crest on top of the snout. A series of vertebrae from the Purbeck Limestones in England, named Pterodactylus macrurus may belong to G. subulatus.
