Pterosaur phylogeny and comments on the evolutionary history of the group
- A. Kellner
- BiologyGeological Society Special Publication
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.

ON A TITANOSAURID (DINOSAURIA, SAUROPODA) VERTEBRAL COLUMN FROM THE BAURU GROUP, LATE CRETACEOUS OF BRAZIL
A new titanosaurid dinosaur from the Late Cretaceous continental deposits of the Bauru Group is described, diagnosed by a combination of characters such as elongated cervicals and middorsals, dorsal vertebrae 9 and 10 with incipient postzygodiapophyseal lamina and transverse processes well developed throughout the sequence formed by anterior and medial caudals.

A new early dinosaur (Sauropodomorpha) from the Caturrita Formation (Late Triassic), Paran Basin, Brazil
Unaysaurus represents the first prosauropod grade dinosaur from Brazil and a preliminary phylogenetic analysis indicates it to be closely related to the European Plateosaurus (Plateosauridae).
New information on the Tapejaridae (Pterosauria, Pterodactyloidea) and discussion of the relationships of this clade

Abstract. A phylogenetic analysis indicates that the Tapejaridae is a monophyletic group of pterodactyloid pterosaurs, diagnosed by the following synapomorphies: premaxillary sagittal crest that…

Taxonomic review of the Ornithocheirus complex (Pterosauria) from the Cretaceous of England
Investigation of the primary literature confirmed that Criorhynchus should be considered an objective junior synonym of Ornithocheirus, and a cladistic analysis demonstrates that Anhangueridae lies within a newly recognized clade, here named AnHangueria, which also includes the genera Cearadactylus, Brasileodactyls, Ludodactelus, and Camposipterus.
