Biomechanical and physiological influences on the osteohistological deposition of Anhangueria (Pterosauria, Pterodactyloidea)

open access: yesREVISTA BRASILEIRA DE PALEONTOLOGIA, 2015
The study of bone microstructure preserved in fossils provides substantial information about physiology, growth gradients and strategies, and some ecological considerations. Paleohistology is a useful tool for understanding the biological mechanisms of extinct animals. Presented here is the microstructure characterization of two Anhangueria pterosaurs.

Were early pterosaurs inept terrestrial locomotors? [PDF]

open access: yesPeerJ, 2015
Pterodactyloid pterosaurs are widely interpreted as terrestrially competent, erect-limbed quadrupeds, but the terrestrial capabilities of non-pterodactyloids are largely thought to have been poor.

A new ?chaoyangopterid (Pterosauria: Pterodactyloidea) from the Cretaceous Kem Kem beds of southern Morocco [PDF]

open access: yesCretaceous Research, 2020
Abstract A new genus and species of edentulous pterodactyloid pterosaur with a distinctive partial rostrum from the mid-Cretaceous (?Albian/Cenomanian) Kem Kem beds of southeast Morocco is described. The taxon is assigned to Chaoyangopteridae based upon its edentulous jaws, elongate rostrum and slightly concave dorsal outline.

The first pterosaur from the Bauru Group: an azhdarchid from the Upper Cretaceous of Brazil

open access: yesPapers in Palaeontology, Volume 11, Issue 5, September/October 2025.
Abstract The vertebrate fossil record of the Bauru Group (Upper Cretaceous, southeastern Brazil) is remarkably rich, with a predominance of titanosaurs and crocodyliforms, alongside theropods, turtles, squamates, fishes and even small mammals. In contrast, pterosaur remains from the Bauru Group have remained elusive until now.

Micro-XRF chemical elementary analysis on the holotype of Sinopterus atavismus Lü, Teng, Sun, Shen, Li, Gao, Liu, 2016 (Pterodactyloidea, Tapejaridae) [PDF]

open access: yesAnais da Academia Brasileira de Ciências
The Early Cretaceous pterosaur Sinopterus atavismus, from Northeast China, belongs to the Tapejaridae. The furrowed structure of its wing phalanges is relatively primitive, possibly indicative of atavism.
