Unwin and Deeming argued that the thin shells of the recently discovered pterosaur eggs suggest that they were buried after laying rather than "brooded" like birds and pop cultural portrayals. [17] Bennett published a study on the anatomy and evolution of the pterosaur wing. [133] Steel published a study on the histology of pterosaur bones. [133]

The first known pterosaur eggs were found in the quarries of Liaoning, the same place that yielded feathered dinosaurs, and in Loma del Pterodaustro (Lagarcito Formation, Argentina). The eggs from Liaoning were squashed flat with no signs of cracking, so evidently the eggs had leathery shells, as in modern lizards. [192]
A new discovery of pterosaur eggs & fossils from the Hamipterus tianshanensis species in China gives us our most complete look at the early flying reptiles.
The ptersosaur lived roughly 170 million years ago and ruled the skies with a wingspan of more than 8 feet, roughly equivalent to a modern-day albatross.
A few years ago, Maria McNamara was invited to Brussels by fellow paleontologist Pascal Godefroit and presented with an intriguing opportunity.
Adult male Pteranodon were among the largest pterosaurs, and were the largest flying animals known until the late 20th century, when the giant azhdarchid pterosaurs were discovered. The wingspan of an average adult male Pteranodon was 5.6 m (18 ft).
Different phylogenetic analyses found it as a basal pterosauromorph, [4] [5] a non-aphanosaurian, non-pterosaur basal avemetatarsalian, a basal dinosauromorph, [11] or a basal archosauriform. [12] This has resulted in a large gap between the fully aerial pterosaurs and their terrestrial ancestors, as the earliest pterosaurs were already capable ...
