Austriadactylus is a genus of "rhamphorhynchoid" pterosaur. The fossil remains were unearthed in Late Triassic (middle Norian age) rocks of Austria. The genus was named in 2002 by e.a.. The type species is Austriadactylus cristatus. The genus name is derived from Latin Austria and Greek daktylos, "finger", in reference to the wing finger of pterosaurs. The specific epithet means "crested" in Latin, a reference to the skull crest. The flexible tail did not have the stiffening rod-like vertebral extensions present in other basal pterosaurs. The wingspan has been estimated at about 120 cm.
