New insights into the skull of Istiodactylus latidens (Ornithocheiroidea, Pterodactyloidea). [PDF]

open access: yesPLoS ONE, 2012
The skull of the Cretaceous pterosaur Istiodactylus latidens, a historically important species best known for its broad muzzle of interlocking, lancet-shaped teeth, is almost completely known from the broken remains of several individuals, but the length

A new pterosaur (Pterodactyloidea: Azhdarchidae) from the Upper Cretaceous of Morocco. [PDF]

open access: yesPLoS ONE, 2010
The Kem Kem beds in South Eastern Morocco contain a rich early Upper (or possibly late Lower) Cretaceous vertebrate assemblage. Fragmentary remains, predominantly teeth and jaw tips, represent several kinds of pterosaur although only one species, the ...

A Basal Tapejarine (Pterosauria; Pterodactyloidea; Tapejaridae) from the Crato Formation, Early Cretaceous of Brazil. [PDF]

open access: yesPLoS ONE, 2016
A three-dimensional and almost complete pterosaur mandible from the Crato Formation (Early Cretaceous of Northeastern Brazil), Araripe Basin, is described as a new species of a tapejarine tapejarid.

A new crested pterosaur from the Early Cretaceous of Spain: the first European tapejarid (Pterodactyloidea: Azhdarchoidea). [PDF]

open access: yesPLoS ONE, 2012
BackgroundThe Tapejaridae is a group of unusual toothless pterosaurs characterized by bizarre cranial crests. From a paleoecological point of view, frugivorous feeding habits have often been suggested for one of its included clades, the Tapejarinae.

The toothless pterosaur Jidapterus edentus (Pterodactyloidea: Azhdarchoidea) from the Early Cretaceous Jehol Biota and its paleoecological implications. [PDF]

open access: yesPLoS ONE, 2017
In the Early Cretaceous Jehol Biota, the toothless pterosaurs flourished with the chaoyangopterids and tapejarids playing a key role in understanding the early diversity and evolution of the Azhdarchoidea.

Short note on a Pteranodontoid pterosaur (Pterodactyloidea) from western Queensland, Australia [PDF]

open access: yesAnais da Academia Brasileira de Ciências, 2011
Flying reptiles from Australia are very rare, represented mostly by isolated bones coming from the Early Cretaceous (Albian) Toolebuc Formation, which crops out in western Queensland.

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.

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 ...
