On the systematic and stratigraphic significance of pterosaurs from the Lower Cretaceous Yixian Formation (Jehol Group) of Liaoning, China [PDF]

open access: yesFossil Record, 2000
A reassessment of the systematic relationships of pterosaurs from the Lower Cretaceous Yixian Formation of Liaoning Province, China, shows that Dendrorhynchoides should be reassigned to the Anurognathidae (“Rhamphorhynchoidea”) and that Eosipterus ...

A new small-bodied azhdarchoid pterosaur from the lower cretaceous of England and its implications for pterosaur anatomy, diversity and phylogeny. [PDF]

open access: yesPLoS One, 2013
BACKGROUND: Pterosaurs have been known from the Cretaceous sediments of the Isle of Wight (southern England, United Kingdom) since 1870. We describe the three-dimensional pelvic girdle and associated vertebrae of a small near-adult pterodactyloid from ...

Resistance of cervical vertebrae in response to muscular stresses in pterosaurs: implications for foraging habits and skeletal pneumatization [PDF]

open access: yesPeerJ
The necks of pterosaurs were flexible and provided mobility for a relatively long skull. The varied morphologies and levels of pneumatization of their cervical vertebrae reflected differences in biomechanical behavior.

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.
