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 ...
Tapejaridae (from a Tupi word meaning "the lord of the ways") is a family of azhdarchoid pterosaurs from the Cretaceous period. Members are currently known from Brazil, England, Hungary, Morocco, [1] Spain, [2] the United States, [3] and China. The most primitive genera were found in China, indicating that the family has an Asian origin. [4]
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.
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 discovery of Skiphosoura and another species called Dearc sgiathanach, which lived roughly 170 million years ago in Scotland, have helped clarify key events in pterosaur evolution ...
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.
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.
Peteinosaurus (/ p ɛ ˌ t aɪ n ə ˈ s ɔːr ə s / peh-TY-nə-SOR-əs; [1] meaning "winged lizard") was a prehistoric genus of pterosaur.It lived in the late Triassic period in the late Norian age (about 218-215 million years ago), [2] and at a wingspan of around 60 cm (24 in), was one of the smallest and earliest pterosaurs, [3] although other estimates suggest a wingspan of up to 1 m (3.3 ...
