Anurognathus

Anurognathus is a genus of small pterosaur that lived during the late Jurassic Period (Tithonian stage). Anurognathus was first named and described by Ludwig Döderlein in 1923.[1]  The type species is Anurognathus ammoni. The genus name Anurognathus is derived from the Greek αν/an- ("without"), оυρα/oura ("tail"), and γναθος/gnathos ("jaw") in reference to its unusually small tail relative to other "rhamphorhynchoid" (i.e. basal) pterosaurs.[2]  The specific name ammoni honours the Bavarian geologist Ludwig von Ammon, from whose collection Döderlein had acquired the fossil in 1922.
