RETRACTED ARTICLE: A new azhdarchoid pterosaur from the Late Cretaceous Javelina Formation of Texas

A historic specimen described for the first time revealed important autapomorphic characters, permitting definition of a new species, Javelinadactylus sagebieli gen. n. et sp. n., which represents second toothless species from Javelina Formation, Big Bend National Park West Texas (United States America). The remains J. (Azhdarchoidea: Tapejaridae) were found in 1986, but never properly studied, and its taxonomic affinity undefined. description is based on partially articulated skull mandible, offer information anatomy single azhdarchoid pterosaur. exhibit large nasoantorbital fenestra, rostral index medium value assigned to clade Thalassodrominae, group tapejarid pterosaurs that reported exclusively Romualdo Formation Brazil, with only two genera known. Thalassodromines are characterized by typical cranial configuration jaws high wide premaxilla bar, formed sub-parallel or parallel borders. here record Tapejaridae Maastrichtian North America, morphology taxon increase richest diversity during end Late Cretaceous, suggesting tapejarids still diversifying Maastrichtian.
