Egg shape changes at the theropod–bird transition, and a morphometric study of amniote eggs [PDF]
The eggs of amniotes exhibit a remarkable variety of shapes, from spherical to elongate and from symmetrical to asymmetrical. We examine eggshell geometry in a diverse sample of fossil and living amniotes using geometric morphometrics and linear ...

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

The Evolution of Pneumatic Foramina in Pterosaur Vertebrae
: 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.

Discrete and continuous character-based disparity analyses converge to the same macroevolutionary signa. A case study from captorhinids [PDF]
The relationship between diversity and disparity during the evolutionary history of a clade provides unique insights into evolutionary radiations and the biological response to bottlenecks and to extinctions.

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

Rise of Dinosaurs Reveals Major Body-Size Transitions Are Driven by Passive Processes of Trait Evolution [PDF]
A major macroevolutionary question concerns how long-term patterns of body-size evolution are underpinned by smaller scale processes along lineages.
