Development and evolution of the notarium in Pterosauria [PDF]
AbstractThe notarium is the structure formed by fusion of the dorsal vertebrae which occurred independently in pterosaurs and birds. This ankylosis usually involves two to six elements and in many cases, also includes the last cervical vertebra. Fusion can occur in different degrees, uniting the vertebral centra, the neural spines, the transverse ...

A REEXAMINATION OF FOUR PROLACERTIFORMS WITH IMPLICATIONS FOR PTEROSAUR PHYLOGENESIS [PDF]
Traditionally, pterosaurs have been included within the Archosauriformes and many contemporary workers consider the Pterosauria the sister group to Lagosuchus, Scleromochlus and the Dinosauria.

Comparative Analysis of the Vertebral Pneumatization in Pterosaurs (Reptilia: Pterosauria) and Extant Birds (Avialae: Neornithes) [PDF]
Birds and pterosaurs have pneumatic bones, a feature likely related to their flight capabilities but whose evolution and origin is still poorly understood.

A small accumulation of bones from the Norian (Upper Triassic) of the Seazza Brook Valley (Carnic Prealps, Northern Italy) was originally (1989) identified as a gastric pellet made of pterosaur skeletal elements.

Reconstruction of the adductor chamber and predicted bite force in pterodactyloids (Pterosauria)
Abstract The reconstruction of jaw muscles is critical in establishing potential cranial functions; however, myological studies of extinct groups that have no descendants are difficult to perform and test. This is particularly true for pterosaurs, a group of extinct flying reptiles that present a plethora of cranial morphologies ...
