ABSTRACT Azhdarchid pterosaurs have been known since 1972 from upper Campanian deposits of Alberta, Canada. Originally represented by only very fragmentary remains tentatively assigned to the genus Quetzalcoatlus, additional material uncovered over the years has revealed that the taxonomic identity of the Alberta pterosaur material is at odds with this in the light of the growing understanding of azhdarchid diversity. Here, we describe previously undocumented pterosaur remains from Alberta and… 
A large pteranodontid pterosaur from the Late Cretaceous of Eastern Europe
The Campanian Beloe Ozero locality within the Rybushka Formation in Saratov Province, Russia, is one of the richest and most diverse Upper Cretaceous pterosaur localities in Europe. It produces

ABSTRACT The Azhdarchidae have come to be known as the most diverse clade of Late Cretaceous pterosaurs and the largest flying creatures in existence. Since the erection of the taxon nearly four
An articulated pterosaur wing from the Upper Cretaceous (Maastrichtian) phosphates of Morocco
Abstract A new and articulated specimen of a pterosaur wing including the humerus, radius/ulna, parts of the carpus and metacarpus and a first wing phalanx from Maastrichtian phosphatic deposits of
A large pterosaur limb bone from the Kaiparowits Formation (late Campanian) of Grand Staircase-Escalante National Monument, Utah, USA
A large pterosaur bone from the Kaiparowits Formation of southern Utah, USA, is tentatively identified as an ulna, although its phylogenetic placement cannot be precisely constrained beyond Pterosaurusia.
Morphology and Taxonomy of Quetzalcoatlus Lawson 1975 (Pterodactyloidea: Azhdarchoidea)
ABSTRACT Quetzalcoatlus is the largest flying organism ever known and one of the most familiar pterosaurs to the public. Despite a half century of interest, it remains very incompletely described.
A new specimen of Sinopterus dongi (Pterosauria, Tapejaridae) from the Jiufotang Formation (Early Cretaceous, China)
A new postcranial specimen, D3072, is presented, which is attributed to the type-species of the genus, Sinopterus dongi, which helps shed some new light in the osteology of Sinopteri complex, hopefully serving as a basis for future comparative studies involving further specimens and other proposed species and, subsequently, taxonomic revisions.
On the pterosaur Aerotitan sudamericanus (Neuquén Basin, Upper Cretaceous of Argentina), with comments on azhdarchoid phylogeny and jaw anatomy
Abstract Aerotitan sudamericanus, from the Upper Cretaceous of the Neuquen Basin (Patagonia, Argentina), is known from a partial jaw fragment which has been interpreted as either an azhdarchid upper
Geology and paleontology of the Upper Cretaceous Kem Kem Group of eastern Morocco
The Kem Kem vertebrate assemblage, currently the best documented association just prior to the onset of the Cenomanian-Turonian marine transgression, captures the taxonomic diversity of a widespread northern African fauna better than any other contemporary assemblages from elsewhere in Africa.
Soaring styles of extinct giant birds and pterosaurs
The results confirmed those from previous studies that Pteranodon and Argentavis magnificens used thermal soaring and indicated that Pelagornis sandersi and Quetzalcoatlus had a poor ability both in dynamic and thermal soaring.


A new late Cretaceous azhdarchid (Pterosauria, Azhdarchidae) from the Volga Region
A new azhdarchid genus and species, Volgadraco bogolubovi gen. et sp. nov., is described based on an anterior fragment of the mandibular symphysis (mandibular beak) and some postcranial elements from
Cranial remains of Quetzalcoatlus (Pterosauria, Azhdarchidae) from Late Cretaceous sediments of Big Bend National Park, Texas
ABSTRACT Numerous remains of the azhdarchid pterosaur Quetzalcoatlus sp., have been recovered over the last twenty years from the Late Cretaceous (Maastrichtian) rocks in Big Bend National Park in
Azhdarchid pterosaur from the Upper Cretaceous (Turonian) of Utah, USA
Abstract Azhdarchids are large pterosaurs from the Cretaceous, known mostly from fragmentary skeletal material. Here, we describe an azhdarchid pterosaur (OMNH 22014) collected from the middle
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
First evidence of azhdarchid pterosaurs from the late cretaceous of Hungary
New remains of an azhdarchid pterosaur were discovered from the Upper Cretaceous (Santonian) Csehbanya Formation at the Iharkut vertebrate locality in the Bakony Mountains, western Hungary. Among the
