Titre: Osteology of Rebbachisaurus garasbae Lavocat, 1954, a diplodocoid (Dinosauria, Sauropoda) from the early Late Cretaceous-aged Kem Kem beds of southeastern Morocco Auteur:Wilson, Jeffrey A; Allain, Ronan Sujet:Geology Description:
The holotype of the sauropod dinosaur Rebbachisaurus garasbae was discovered in infra-upper Cenomanian horizons of the Kem Kem region of southeastern Morocco in the 1940s and 1950s. The original materials included part of a vertebral column, some of which was found in articulation, and a scapula, a humerus, and an ischium. Of these remains, only the scapula and one of the dorsal vertebrae have been described, but in abbreviated form. Following complete preparation of the partial skeleton, careful examination and fitting of scores of fragments collected with these materials, and computed tomography imaging of the most complete vertebra, we present a complete description of the holotype of Rebbachisaurus garasbae. Our description identifies several autapomorphies of the dorsal and caudal vertebrae, both relating to the shape of the vertebrae and the architecture of their laminae. Based on our reassessment of its anatomy, Rebbachisaurus is recovered as a member of an Afro-European...

Titre: Rediscovery of the type localities of the Late Cretaceous Mongolian sauropods Nemegtosaurus mongoliensis and Opisthocoelicaudia skarzynskii: Stratigraphic and taxonomic implications Auteur:Currie, Philip J; Wilson, Jeffrey A; Fanti, Federico; Mainbayar, Buuvei; Tsogtbaatar, Khishigjav Sujet:Upper Cretaceous ; Nemegt Formation ; Baruungoyot Formation ; Sauropoda ; Titanosauria ; Upper Cretaceous ; Nemegt Formation ; Baruungoyot Formation ; Sauropoda ; Titanosauria ; Geology Description:
In 1965, the Polish-Mongolian Palaeontological Expeditions recovered two sauropods from the Nemegt Formation of the Nemegt Basin, Mongolia (Kielan-Jaworowska and Dovchin 1968). One specimen, a nicely preserved, complete skull that in 1971 became the holotype of Nemegtosaurus mongoliensis, was found in Central Sayr at the Nemegt Locality. The other was found at Altan Uul IV and is a nearly complete postcranial skeleton lacking only the skull and neck. In 1977, this skeleton became the holotype of Opisthocoelicaudia skarzynskii. Nemegtosaurus and Opisthocoelicaudia were initially assigned to different sauropod higher taxa, Dicraeosaurinae and Camarasauridae respectively. However, since the late 1990s, both genera have been recognized as members of Titanosauria. Their coincident spatiotemporal distribution and non-overlapping skeletal parts have led to the persistent suspicion that they belong to the same species. Rediscovery of the original quarries and discovery of the postcranial...

Titre: The end of the sauropod dinosaur hiatus in North America Auteur:D'Emic, Michael D; Wilson, Jeffrey A; Thompson, Richard Sujet:Dinosaur ; Sauropod ; Titanosaur ; Alamosaurus ; Hadrosaur ; Biogeography ; Cretaceous ; Dinosaur ; Sauropod ; Titanosaur ; Alamosaurus ; Hadrosaur ; Biogeography ; Cretaceous ; Geology Description:
Sauropod dinosaurs reached their acme in abundance and diversity in North America during the Late Jurassic. Persisting in lesser numbers into the Early Cretaceous, sauropods disappeared from the North American fossil record from the Cenomanian until the Campanian or Maastrichtian stage of the Late Cretaceous. This ca. 25–30 million-year long sauropod hiatus has been attributed to either a true extinction, perhaps due to competition with ornithischian dinosaurs, or a false extinction, due to non-preservation of sediments bearing sauropods. The duration of the sauropod hiatus remains in question due to uncertainty in the ages and affinities of the specimens bounding the observed gap. In this paper, we re-examine the phylogenetic affinity of materials from Campanian-aged sediments of Adobe Canyon, Arizona that currently mark the end of the sauropod hiatus. Based on the original description of those remains and new specimens from the same formation, we conclude that the Adobe Canyon...
