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.
In
2017 a former species of Germanodactylus, G.
rhamphastinus, was renamed
as its own genus, Altmuehlopterus.
