COMMENTS ON TRIASSIC PTEROSAURS WITH A COMMENTARY ON THE "ONTOGENETIC STAGES" OF KELLNER (2015) AND THE VALIDITY OF BERGAMODACTYLUS WILDI

Rivista Italiana di Paleontologia e Stratigrafia, 2018
Six stages (OS1-6) were identified by Kellner (2015) to establish the ontogeny of a given pterosaur fossil. These were used to support the erection of several new Triassic taxa including Bergamodactylus wildi, which is based on a single specimen (MPUM ...

Extending the Geographic Range of Pterosaurs in the Araripe Basin: First Record from the Romualdo Formation (Araripe Basin) in Piauí, Brazil [PDF]

Anais da Academia Brasileira de Ciências
The Araripe Basin in northeastern Brazil is a key site for Cretaceous pterosaur fossils from Gondwanan deposits. Most discoveries are concentrated in its northern portion, particularly in Ceará state, within the Crato and Romualdo formations. In contrast,

New information on the Wukongopteridae (Pterosauria) revealed by a new specimen from the Jurassic of China

PeerJ, 2016
The Wukongopteridae is an important pterosaur group discovered from Yanliao Biota, because it combines character states seen in non-pterodactyloid and pterodactyloid pterosaurs. So far, the Wukongopteridae contains three genera:Wukongopterus,DarwinopterusandKunpengopterus; representing five species.

The Evolution of Pneumatic Foramina in Pterosaur Vertebrae

Anais da Academia Brasileira de Ciências, 2019
: Pterosaurs possess skeletal pneumatization, which can be assessed externally through the observation of pneumatic foramina. These foramina vary in position, shape, and number among taxa.

Pneumatic postcranial bones in dinosaurs and other archosaurs

, 1993
Bibliography: p. 290-317Among amniotes, pneumatic postcranial bones are shared by Aves, Theropoda, Sauropoda, and Pterosauria. Comparison of pneumatic characters in the vertebrae of birds and non-avian dinosaurs demonstrates that the Theropoda and the ...

Eggshell and Histology Provide Insight on the Life History of a Pterosaur with Two Functional Ovaries

Anais da Academia Brasileira de Ciências, 2015
The counterpart of a previously described non-pterodactyloid pterosaur with an egg revealed the presence of a second egg inside the body cavity of this gravid female.

Exploring the complex cranial morphology of Tupandactylus imperator (Pterodactyloidea, Tapejaridae) based on a new specimen [PDF]

Anais da Academia Brasileira de Ciências
Tupandactylus imperator, a striking tapejarid pterosaur from the Lower Cretaceous (Aptian) Crato Formation (Araripe Basin), is renowned for its extraordinary cranial crest, one of the proportionally largest among pterosaurs and, indeed, also among all ...

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

REVISTA 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.
