A new complete and fully articulated juvenile specimen of the
rhamphorhynchoid pterosaur Scaphognathus crassirostris from the Upper
Jurassic Solnhofen Limestone of southern Germany is only the third
known specimen of the species. The specimen is described and compared
to the other two specimens. Based on the comparisons, the skull of
Scaphognathus is reinterpreted as having two premaxillary, six
maxillary, and five dentary teeth per jaw side, and a broad
boat-shaped snout. Scaphognathus is compared to Jianchangnathus
robustus, and revised diagnoses of the genus and family are presented.
In addition, the position of the cervico-dorsal transition in the
vertebral column of pterosaurs is reviewed, and an apparent constraint
to nine cervical vertebrae is noted.
