New fossil remains of Mendozasaurus neguyelap ( Sauropoda , Titanosauria ) of the Late Cretaceous of Mendoza , Argentina

In this context, the discovery of cervical remains assigned to Mendozasaurus neguyelap González Riga is relevant from a systematic viewpoint. The fossils were found in the paleontological site and assemblage of the holotype, Río Neuquén Subgroup, late Turonian – l...

متن کاملThe Behavioral Implications of a Multi-Individual Bonebed of a Small Theropod Dinosaur
BACKGROUND Central Patagonia, Argentina, preserves an abundant and rich fossil record. Among vertebrate fossils from the Upper Cretaceous Bajo Barreal Formation of Patagonia, five individuals of the small, non-avian theropod dinosaur Aniksosaurus darwini were recovered. Group behavior is an important aspect of dinosaur paleoecology, but it is not well-documented and is poorly understood among n...
متن کاملThe Basal Titanosaurian Rukwatitan Bisepultus (dinosauria, Sauropoda) from Themiddle Cretaceous Galula Formation, Rukwarift Basin, Southwestern Tanzania
Whereas titanosaurians represent the most diverse and cosmopolitan clade of Cretaceous sauropod dinosaurs, they remain rare components of Cretaceous African faunas. Currently recognized continental African titanosaurians include Aegyptosaurus baharijensis and Paralititan stromeri from early Upper Cretaceous deposits near Bahariya Oasis, Egypt, and Malawisaurus dixeyi and Karongasaurus gittelman...
