spent the early years of its classification as a specimen of
kocki. However in 1964, Yang Zhongjian noted
differences, and created the Germanodactylus genus.
The second species
of Germanodactylus, G. rhamphastinus,
was actually discovered back
in1858, although this time the specimen was referred to Ornithcephalus,
a genus that is no longer considered valid with all fossils once
attributed to it found to actually belong to other genera. G.
rhamphastinus has a larger crest, and slightly more teeth
cristatus, with thirty-two in the upper jaw (twenty-six in G.
cristatus) and thirty in the lower jaw (twenty-four in G.
The teeth of G. rhamphastinus also extend to the
tip of the jaw, where
as they are absent from the tip of the jaw of G.cristatus.
Possibly the main feature of interest to researchers of Germanodactylus is the head crest. Although quite unremarkable compared to some other pterosaurs like Nyctosaurus or Tupandactylus, it is a good example of the early forms that seem to be more common to the more advanced pterodactyloid pterosaurs. The crest itself is best known from the bony growth that rises from the top of its skull. In 2002, S. Cristopher Bennet realised that this growth was merely the base for a much larger crest that was made from soft tissue. By having a crest made of soft tissue, probably keratin, Germanodactylus may have had a crest that actively changed colour to be more vivid during the breeding season.
