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 ...
This list of pterosaurs is a comprehensive listing of all genera that have ever been included in the order Pterosauria, excluding purely vernacular terms.The list includes all commonly accepted genera, but also genera that are now considered invalid, doubtful (nomen dubium), or were not formally published (nomen nudum), as well as junior synonyms of more established names, and genera that are ...
Pterosaurs [b] [c] are an extinct clade of flying reptiles in the order Pterosauria. They existed during most of the Mesozoic: from the Late Triassic to the end of the Cretaceous (228 million to 66 million years ago). [8] Pterosaurs are the earliest vertebrates known to have evolved powered flight.
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 ...
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.
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.
