The split between dinosaurs and pterosaurs occurred just after aphanosaurs branched off the archosaur family tree. This split corresponds to the subgroup Ornithodira ( Ancient Greek ὄρνις ( órnis , “bird”) + δειρή ( deirḗ , “throat”), defined as the last common ancestor of dinosaurs and pterosaurs, and all of its descendants.
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.
This timeline of pterosaur research is a chronologically ordered list of important fossil discoveries, controversies of interpretation, and taxonomic revisions of pterosaurs, the famed flying reptiles of the Mesozoic era. Although pterosaurs went extinct millions of years before humans evolved, humans have coexisted with pterosaur fossils for ...
Highly simplified pterosaur phylogeny – topology based on that recovered by Unwin [1] This phylogeny of pterosaurs entails the various phylogenetic trees used to classify pterosaurs throughout the years and varying views of these animals. Pterosaur phylogeny is currently highly contested and several hypotheses are presented below.
They each placed the group at the base of Avemetatarsalia, outside of Ornithodira (the group containing pterosaurs, dinosaurs, and most other avemetatarsalians). A simplified strict consensus tree (a family tree with the fewest steps in evolution) using the Nesbitt (2011) analysis is given below: [1]
A few years ago, Maria McNamara was invited to Brussels by fellow paleontologist Pascal Godefroit and presented with an intriguing opportunity.
Nyctosauridae (meaning "night lizards" or "bat lizards") is a family of specialized soaring pterosaurs of the late Cretaceous Period of North America, Africa, and possibly other continents including South America. It was named in 1889 by Henry Alleyne Nicholson and Richard Lydekker. [2]
A team led by palaeontologists at the University of Edinburgh used new laser technology to study the tail vane on a 150-million-year-old fossil.
