Pterosaurs are the oldest known powered flying vertebrates. Originating in the Late Triassic, they thrived to the end of the Cretaceous. Triassic pterosaurs are extraordinarily rare and all but one specimen come from marine deposits in the Alps. A new comparatively large (wing span >150 cm) pterosaur, Caelestiventus hanseni gen. et sp. nov., from Upper Triassic desert deposits of western North America preserves delicate structural and pneumatic details not previously known in early pterosaurs… Expand
Seazzadactylus venieri gen. et sp. nov., a new pterosaur (Diapsida: Pterosauria) from the Upper Triassic (Norian) of northeastern Italy
A new non-monofenestratan pterosaur with multicusped dentition, Seazzadactylus venieri, is described from the Upper Triassic of the Carnian Prealps (northeastern Italy), showing unique features. Expand
Seazzadactylus venieri gen. et sp. nov., a new pterosaur (Diapsida: Pterosauria) from the Upper Triassic (Norian) of northeastern Italy.
A new non-monofenestratan pterosaur with multicusped dentition, Seazzadactylus venieri, is described from the Upper Triassic (middle-upper Norian) of the Carnian Prealps (northeastern Italy). TheExpand
New sphenodontian (Reptilia: Lepidosauria) from a novel Late Triassic paleobiota in western North America sheds light on the earliest radiation of herbivorous lepidosaurs
Abstract. Herbivory is a common ecological function among extant lepidosaurs, but little is known about the origin of this feeding strategy within Lepidosauria. Here we describe a sphenodontianExpand
First record of a Late Jurassic rhamphorhynchine pterosaur from Gondwana
We describe partial remains of a non-pterodactyloid pterosaur from Upper Jurassic levels of the Atacama Desert in northern Chile. The material includes a left humerus, a possible dorsal vertebra, andExpand
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.

Testing pterosaur ingroup relationships through broader sampling of avemetatarsalian taxa and characters and a range of phylogenetic analysis techniques
This study has, for the first time, included taxa that represent the aphanosaurs, lagerpetids, silesaurids and dinosaurs, in addition to early pterosaurs, and tests the relationships between the early diverging pterosaur taxa following the addition of avemetatarsalian taxa and anatomical characters to an existing early pTerosaur dataset.

A Non-Averostran Neotheropod Vertebra (Dinosauria: Theropoda) from the Earliest Jurassic Whitmore Point Member (Moenave Formation) in Southwestern Utah
ABSTRACT Theropod dinosaurs are minor components of Late Triassic ecosystems in North America, comprising coelophysoids and various non-neotheropods from the Chinle Formation of Arizona, Utah,Expand
Sinomacrops bondei, a new anurognathid pterosaur from the Jurassic of China and comments on the group
This work presents a new genus and species from the Middle-Late Jurassic Tiaojishan Formation, the third nominal anurognathid speciesFrom the Jurassic of China, and provides a new phylogenetic analysis incorporating into a single data set characters from diverging phylogenetic proposals. Expand
Assessing ontogenetic maturity in extinct saurian reptiles
The various methods that have been used to assess maturity in every major saurian group are described, integrating data from both extant and extinct taxa to give a full account of the current state of the field and providing method‐specific pitfalls, best practices, and fruitful directions for future research.

A Jurassic pterosaur from Patagonia and the origin of the pterodactyloid neurocranium
A µCT ray-generated virtual endocast shows that the new pterosaur exhibits a mosaic of plesiomorphic and derived traits of the inner ear and neuroanatomy that fills an important gap between those of non-monofenestratan breviquartossans (Rhamphorhynchidae) and derived pterodactyloids. Expand
Discovery of a Rare Pterosaur Bone Bed in a Cretaceous Desert with Insights on Ontogeny and Behavior of Flying Reptiles
The available information suggests that this species was gregarious, living in colonies, and most likely precocial, being able to fly at a very young age, which might have been a general trend for at least derived pterosaurs. Expand
Comments on Triassic pterosaurs with discussion about ontogeny and description of new taxa.
The present study increases the diversity of Triassic flying reptiles and further pushes the origins of this clade back to at least the Middle Triassic. Expand
A New Pterosaur from the Jurassic of Cuba
Cacibupteryx caribensis gen. et sp. nov. is a new pterosaur of the family Rhamphorhynchidae found in western Cuba, in rocks of the Jagua Formation (Middle–Upper Oxfordian). The holotype, a skull andExpand
