Scaphognathus[40]

S. crassirostris[40]

  1. Only two specimens have been recovered from the formation.[40] The first was found in Eichstätt, the second in Mülheim.[40]
  • A Solnhofen genus erected in 1861 by J. A. Wagner when he recognized the rhamphorhynchoid nature of "Pterodactylus" crassirostris after the discovery of a specimen with a preserved tail.[40] The Solnhofen Limestone is the only known source of Scaphognathus fossils.[40]
  1. S. crassirostris was originally named P. crassirostris in 1831 by August Goldfuss who mistook the tailless specimen for a new Pterodactylus species.[40]
