An archosaur flying-reptile radiation usually placed within Ornithodira near dinosaurs, while its precise origin remains analysis-dependent; package evidence spans eggs, soft tissues and bounded launch models.

taxonomy · high
Review and expanded anatomical analyses place Pterosauria within archosaur Ornithodira near dinosaurs, but its precise origin and closest relatives remain analysis-dependent.
claim:taxon:pterosauria:taxonomyfossil-range · medium
The Pterosauria navigation envelope retains a rounded 228 Ma older edge for the Norian Carniadactylus sample and a broad 66 Ma younger edge; the named specimens support Late Triassic pterosaur presence but not an exact global first or last appearance, clade-origin date or direct ancestry.
claim:taxon:pterosauria:fossil-rangebiogeography · high
Pterosaur remains are reported from every continent, but a 108-taxon analysis finds the record extremely patchy; package dossiers therefore remain tied to named specimens and localities rather than a complete distribution.
claim:taxon:pterosauria:biogeographymorphology · high
Pterosaurs support a membranous wing primarily on an elongate fourth finger; launch capacity and flight performance are biomechanical model outputs rather than preserved motions.
claim:taxon:pterosauria:morphologyecology · high
Pterosaurs occupied diverse aerial and coastal guilds, so no single diet, launch mode or habitat is generalized to the entire radiation.
