The wandering jaws of Istiodactylus latidens (Pterosauria, Istiodactylidae)
Cretaceous Research, 2021Abstract A new specimen of the Early Cretaceous pterodactyloid pterosaur Istiodactylus latidens is described. This specimen in the Moscow Vernadsky State Geological Museum represents the associated anterior ends of the rostrum and mandibular symphysis but lacks collection data.

A preliminary analysis of dental microstructure in Hamipterus (Pterosauria, Pterodactyloidea)
The Anatomical Record, 2023AbstractThe toothed members of Pterosauria display an extremely wide range of tooth morphologies that supported a variety of feeding habits. Histological studies on the teeth of different pterosaur clades are potentially valuable in understanding the development of their tooth diversity.

A new ctenochasmatid (Pterosauria, Pterodactyloidea) from the late Jurassic of Uruguay
Journal of South American Earth Sciences, 2021Abstract A new ctenochasmatid pterosaur from the Tacuarembo Formation (Late Jurassic of Uruguay), Tacuadactylus luciae gen. et sp. nov. is described, based on a rostrum fragment with spatulated tip and dentary fragments. It closely resembles Gnathosaurus in the orientation of the teeth and the presence of interalveolar concavities.

Cope's Rule in the Pterosauria, and differing perceptions of Cope's Rule at different taxonomic levels [PDF]
Journal of Evolutionary Biology, 2007 AbstractThe remarkable extinct flying reptiles, the pterosaurs, show increasing body size over 100 million years of the Late Jurassic and Cretaceous, and this seems to be a rare example of a driven trend to large size (Cope's Rule). The size increases continue throughout the long time span, and small forms disappear as larger pterosaurs evolve.

Evidence for the presence of Rhamphorhynchus (Pterosauria: Rhamphorhynchinae) in the Kimmeridge Clay of the UK [PDF]
Proceedings of the Geologists Association, 2015 Abstract The second pterosaur genus to be established, Rhamphorhynchus von Meyer, 1847 , has historically been used as a wastebasket material. Several species have been erected for fossils found in Europe and Africa, the majority of which are based on non-diagnostic material.

Pterosauria from the Late Triassic of Southern Brazil
2010A few postcranial remains of a Late Triassic pterosaur from the early Coloradian Caturrita Formation of Rio Grande do Sul are communicated. The general morphology of the coracoid, proximal portion of the humerus, femur, tibia and fibula suggests that it is more primitive than the pterosaurs from the Norian of northern Italy.

VI.—Mr. E. T. Newton on Pterosauria
Geological Magazine, 1889The paper by Mr. E. T. Newton “ On the Skull of Scaphognathus ” is one of the most important contributions to the morphology of the Pterosauria which has been published. There are a few poii however, which appear to me to need correction or a fuller explanati1. The “prefontals,” Newton.When Mr.

The Early Evolutionary History and Adaptive Radiation of the Pterosauria
Acta Geologica Sinica - English Edition, 2012Abstract:Phylogenetic analyses of early pterosaur species are relatively new and contradictory. However, they imply a similar evolutionary history for early pterosaurs: a large divergence of all major early groups of pterosaurs before the first named pterosaur species appeared in the fossil record.

The phylogenetic position of the Pterosauria within the Archosauromorpha re-examined
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.
