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]
During the 112th Congress, which was in session from 2011-2013, Committee Chairman Ralph Hall added "Space" back into the committee's name: "The Committee on Science, Space, and Technology" – a nod to the committee's history, broad jurisdiction, and the importance of space exploration in maintaining American innovation and competitiveness.

Timeline showing the development of the extinct reptilian order Pterosauria from its appearance in the late Triassic period to its demise at the end of the Cretaceous, together with an alphabetical listing of pterosaur species and their geological ages.
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.
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 ...
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]
An amateur paleontologist has discovered a new species of pterosaur, a flying reptile that lived alongside dinosaurs around 100 million years ago. New pterosaur species discovered by Australian farmer
