A CRESTED RHAMPHORHYNCHOID PTEROSAUR FROM THE LATE TRIASSIC OF AUSTRIA
The earliest pterosaurs are represented by rare, incomplete and bearing small side cusps, posterior multicusped teeth longer specimens from the Upper Triassic (Norian) of Italy (Wild, than tall and…
New information on Bobosaurus forojuliensis (Reptilia: Sauropterygia): implications for plesiosaurian evolution
Bobosaurus shows that the evolution of the plesiosaurian body plan from the ancestral pistosauroid grade was a step-wise process, and that some of the vertebral and appendicular specialisations of Jurassic and Cretaceous plesioaurians had already developed in the earliest Late Triassic.
The Venice specimen of Ouranosaurus nigeriensis (Dinosauria, Ornithopoda)
Osteohistological analysis of some long bones, a rib and a dorsal neural spine reveals that the Venice specimen is a sub-adult; this conclusion is supported by somatic evidence of immaturity.
Enigmatic dinosaur precursors bridge the gap to the origin of Pterosauria
It is demonstrated that lagerpetids—a group of cursorial, non-volant dinosaur precursors—are the sister group of pterosaurs, sharing numerous synapomorphies across the entire skeleton, substantially shortening the temporal and morphological gap between the oldest pterosaurus and their closest relatives and simultaneously strengthens the evidence that pter dinosaurs belong to the avian line of archosaurs.

The results of these analyses favor the hypothesis that aralosaurins and tsintaosaurins were Asian immigrants that reached the Ibero-Armorican island via dispersal events sometime during the Maastrichtian.

A new species of Late Triassic pterosaur, Caelestiventus hanseni, predates all other known desert pterosaurs by 65 million years, showing that from an early point in their evolution, pter dinosaurs were widely geographically distributed and capable of dwelling in harsh environments.
A VERTEBRATE NESTING SITE IN NORTHEASTERN ITALY REVEALS UNEXPECTEDLY COMPLEX BEHAVIOR FOR LATE CARNIAN REPTILES
Abstract We interpret 13 large subcircular or horseshoe-shaped depressions discovered in Late Triassic peritidal carbonate rocks of the Dogna Valley in Udine Province, northeastern Italy, to be…

Comparison with the osteology of a large sample of Middle-Late Triassic reptiles shows some affinity with the protorosaurians, mainly with Langobardisaurus pandolfii that was found in the same formation as the pellet, but differences with this species suggest that the bones belong to a similar but distinct taxon.

ABSTRACT— An articulated skeleton of a hadrosauroid dinosaur, Tethyshadros insularis n. gen., n. sp., was recovered from the Liburnian Formation (uppermost Cretaceous) of Villaggio del Pescatore in…
Re-examination of the purported pterosaur wing metacarpals from the Upper Triassic of England
Two small bones from the Upper Triassic of Cromhall Quarry (Gloucestershire, England), which are referred in the literature to pterosaurian wing metacarpals, are compared with wing metacarpals of…
