Wellnhopterus (lit. 'Wellnhofer's wing') is an azhdarchid pterosaur recovered from the Late Cretaceous Javelina Formation in Texas that was previously identified as a thalassodromine. It consists of a set of upper and lower jaws (TMM 42489-2), as well as some cervical vertebrae (TMM 42489-2.3 to 42489-2.8) and a fragmentary long bone (TMM 42489-2.9). In July 2021, the jaws were given the genus name "Javelinadactylus" (meaning "Javelina Finger"), with the type and only species as "J. sagebieli"; however, this article has now been retracted.[1] In a paper published in December 2021, the complete holotype was independently named Wellnhopterus, with the only species being W. brevirostris. As of 2022, this is the formal name of this pterosaur.
