A REVISION OF THE ANATOMY OF THE TRIASSIC PTEROSAUR AUSTRIADRACO DALLAVECCHIAI KELLNER, 2015 AND OF ITS DIAGNOSIS

open access: yesRivista Italiana di Paleontologia e Stratigrafia, 2021
Several skeletal elements preserved in the holotype and only specimen of the pterosaur Austriadraco dallavecchiai Kellner, 2015 (uppermost Triassic, Austria) have not been identified or have remained undescribed in previous works.

The ankle joint of Pterodaustro guinazui [PDF]

open access: yesActa Palaeontologica Polonica
The hindlimb of pterosaurs has been much less studied than the pterosaur wing. However, it is relevant to understand the evolution, phylogeny and ecology of these animals.

A reappraisal of azhdarchid pterosaur functional morphology and paleoecology [PDF]

open access: yes, 2008
Azhdarchid pterosaurs were among the most widespread and successful of pterosaur clades, but their paleoecology remains controversial. Morphological features common to all azhdarchids include a long, shallow rostrum; elongate, cylindrical cervical ...

Variable preservation potential and richness in the fossil record of vertebrates

open access: yesPalaeontology, Volume 63, Issue 2, Page 313-329, March 2020., 2020
Abstract Variation in preservation and sampling probability clouds our estimates of past biodiversity. The most extreme examples are Lagerstätten faunas and floras. Although such deposits provide a wealth of information and represent true richness better than other deposits, they can create misleading diversity peaks because of their species richness ...

The phylogenetic position of the Pterosauria within the Archosauromorpha [PDF]

open access: yesZoological Journal of the Linnean Society, 1996
In recent years the hypothesis that pterosaurs were the major sister-group of dinosaurs and a closely-linked hypothesis that pterosaurs evolved flight from the ground up have gained general acceptance. A cladistic analysis of the Archosauromorpha using characters presented by previous workers results in a single most parsimonious tree with the ...

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.
