Abstract
While pterosaurs occur in the Lower Jurassic strata of Britain and Germany, only the family Rhamphorhynchidae is currently known found in both. A newly discovered humerus from the Whitby Mudstone Formation of Lincolnshire challenges this and is distinguished from all other Lower Jurassic British pterosaurs by its possession of a quadrangular deltopectoral crest. This is a rare morphotype which only occurs in Eudimorphodon, Austriadraco, Raeticodactylus, Carniadactylus and Campylognathoides. The Lincolnshire humerus compares well with these taxa but is identified as a cf. Campylognathoides sp. based on its age and palaeobiogeography. The genus Campylognathoides is a common pterosaur in the Toarcian Posidonia Shale of Germany and the new humerus supports continuity of pterosaur populations across central Laurasia.
