Pterosaur phylogeny and comments on the evolutionary history of the group
TL;DR: This study suggests that the most primitive taxon is the Anurognathidae, followed by Sordes and all remaining pterosaurs, and the hypothesis of rhamphorhynchoid paraphyly is confirmed, with the RhamphorHynchidae more closely related to the Pterodactyloidea than to more basal forms.
Journal ArticleDOI
Pterosaur diversity and faunal turnover in Cretaceous terrestrial ecosystems in China
TL;DR: Two new pterosaurs that are referred to European groups previously unknown in deposits of northeastern China are reported, showing a wide range of groups including both primitive and derived forms that are not matched by any other deposit in the world.
