A historic specimen described for the first time revealed important autapomorphic characters, permitting the definition of a new species, Javelinadactylus sagebieli gen. n. et sp. n., which represents the second toothless species from the Javelina Formation, Big Bend National Park of West Texas (United States of America). The remains of J. sagebieli (Azhdarchoidea: Tapejaridae) were found in 1986, but were never properly studied, and its taxonomic affinity remains undefined. The description is… 
Paleontological inventory of Paleozoic, Late Mesozoic, and Cenozoic plant, invertebrate, and vertebrate fossil species from Big Bend National Park, Texas, USA - over a century of paleontological discovery
The extraordinary paleontological record from Big Bend National Park (BIBE), Texas chronicles nearly 120 million years of largely uninterrupted deposition through Late Cretaceous, Paleogene and


A New Pterosaur (Pterodactyloidea: Azhdarchidae) from the Upper Cretaceous of Morocco
A new azhdarchid pterosaur is described, Alanqa saharica nov. sp.
A partial pterosaur skull from the Nova Olinda Member of the Crato Formation represents a new edentulous pterodactyloid, Lacusovagus, which shares a shallow, crestless rostrum and a slender posterodorsal premaxillary extension with Jiufotang Forma- tion azhdarchoids such as Chaoyangopterus and Jidapters.
A New Crested Pterosaur from the Early Cretaceous of Spain: The First European Tapejarid (Pterodactyloidea: Azhdarchoidea)
The discovery of Europejara in the Barremian of the Iberian Peninsula reveals an earlier and broader global distribution of tapejarids, suggesting a Eurasian origin of this group.
Hadrosaurian dinosaurs from the Maastrichtian Javelina Formation, Big Bend National Park, Texas
Gryposaurus alsatei was a contemporary of Edmontosaurus, the sole terminal Cretaceous hadrosaur in the northern Great Plains region, and neither possessed the ornate narial crest that characterized many earlier hadrosaurs.

A new unusual tapejarid pterosaur from the Early Cretaceous Romualdo Formation (Araripe Basin, Brazil) is described, based on a skull, lower jaw and some postcranial elements, demonstrating that the evolution of palatal region in pterosaurs is more complex than previously thought.
A new azhdarchoid pterosaur from the Lower Cretaceous of China and its implications for pterosaur phylogeny and evolution
A complete, articulated skeleton of a 1.4-m-wingspan pterosaur from the Lower Cretaceous Jiufotang Formation of Liaoning Province, China is reported and it is identified as a new genus and species, Shenzhoupterus chaoyangensis gen. nov.
A new ceratopsian dinosaur from the Javelina Formation (Maastrichtian) of West Texas and implications for chasmosaurine phylogeny
The combination of primitive and derived traits exhibited by B. polyphemus, and its stratigraphic position, is compatible with the gradual transition from basal, to intermediate, to derived chasmosaurines observed throughout the western interior of North America, and with phylogenetic analysis, which suggests that Bravoceratops may be closely related to Coahuilaceratops.
Mistralazhdarcho Maggii, Gen. Et Sp. Nov., A New Azhdarchid Pterosaur from the Upper Cretaceous of Southeastern France
ABSTRACT A series of pterosaur bones from the Upper Cretaceous (Campanian) of Velaux (Bouches-du-Rhône, southeastern France) is described. This material, including both cranial and postcranial
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
