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]
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.
Many were described by Harry Govier Seeley, at the time the main English expert on the subject, who also wrote the first pterosaur book, Ornithosauria, [105] and in 1901 the first popular book, [92] Dragons of the Air. Seeley thought that pterosaurs were warm-blooded and dynamic creatures, closely related to birds. [106]
A few years ago, Maria McNamara was invited to Brussels by fellow paleontologist Pascal Godefroit and presented with an intriguing opportunity.
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.
Witton's scientific research has revolved largely around the habits, behaviors, systematics, and nomenclature of pterosaurs. [3] His 2013 book Pterosaurs: Natural History, Evolution, Anatomy explores the anatomy, ecology and extinction of pterosaurs, in addition to being fully illustrated. [4] [5]
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 rudimentary feathers are thought to have evolved from reptilian scales nearly 250 million years ago in animals ancestral to dinosaurs and the flying reptiles called pterosaurs.
