Historical Biology, 2013A previous analysis of the phylogenetic position of the Pterosauria argued that pterosaurs were not closely related to dinosaurs as is generally accepted, but rather were outside the crown group Archosauria. However, that study was dismissed for the use of inappropriate methods.

SEM Observation of the Wing Membrane of Beipiaopterus chenianus (Pterosauria)
Acta Geologica Sinica - English Edition, 2005Abstract The cross‐section and surface structures of wing membranes from the ctenochasmatid pterosaur Beipiaopterus chenianus were observed through a scanning electron microscope (SEM). The results show that the wing membrane contains a high density of blood vessels, implying strong thermoregulatory function, similar to that of a bat wing membrane ...

Mid-cretaceous Ornithocheirids (Pterosauria, Ornithocheiridae) from Russia and Uzbekistan
Paleontological Journal, 2007Ornithocheirid remains from 16 localities of Russia and Uzbekistan are reviewed. New material of ornithocheirids from the localities of Mogoito (Barremian-Aptian), Stoilo quarry (Albian-Cenomanian), and Khodzhakul (Cenomanian) is described. The Khodzhakul locality has yielded Ornithocheirus (the first record of this genus in Asia).

A computer reconstruction of isolated cervical vertebrae of Azhdarcho lancicollis from the Turonian of Uzbekistan allows three-dimensional model of the cervical region of the vertebral column of this animal. The relative length of cervical vertebrae (I + II VI > VII > VIII > IX) is the same as in pterodactyloids with short cervical vertebrae.
