A Gigantic, Exceptionally Complete Titanosaurian Sauropod Dinosaur from Southern Patagonia, Argentina
Dreadnoughtus is the most complete giant titanosaur yet discovered, and provides new insight into the morphology and evolutionary history of these colossal animals.
A reappraisal of Notohypshilophodon comodorensis (Ornithischia: Ornithopoda) from the Late Cretaceous of Patagonia, Argentina.
A restudy of Notohypsilophodon is presented, which increases the knowledge of the evolutionary dynamics of South American Cretaceous ornithopods, and broadens theknowledge of the early Late Cret Jurassic continental vertebrate assemblages of central Patagonia and of the Southern Hemisphere in general.
The influence of caudofemoral musculature on the titanosaurian (Saurischia: Sauropoda) tail skeleton: morphological and phylogenetic implications
The differing position of the fourth trochanter, and therefore, the insertion of the caudofemoral muscles, among various titanosaurian taxa suggests distinctions in the locomotor function of these animals.
Histological evidence for a supraspinous ligament in sauropod dinosaurs
The formation of this structure appears to have been a non-pathological metaplastic ossification, possibly induced by the continuous tensile forces applied to the element.
Katepensaurus goicoecheai, Gen. Et Sp. Nov., a Late Cretaceous Rebbachisaurid (Sauropoda, Diplodocoidea) from Central Patagonia, Argentina
ABSTRACT We describe Katepensaurus goicoecheai, gen. et sp. nov., a diplodocoid sauropod dinosaur from the Bajo Barreal Formation (Upper Cretaceous: Cenomanian—Turonian) of south-central Chubut
An overview of the appendicular skeletal anatomy of South American titanosaurian sauropods, with definition of a newly recognized clade.
The results of four recent, largely independent analyses support the existence of a derived titanosaurian lineage distinct from the 'Saltasaurinae line,' which is herein termed Colossosauria.
A Medium-Sized Ornithopod (Dinosauria: Ornithischia) from the Upper Cretaceous Bajo Barreal Formation of Lago Colhué Huapi, Southern Chubut Province, Argentina
ABSTRACT An associated partial postcranial skeleton is described as the third definitive ornithopod dinosaur record from the Upper Cretaceous Bajo Barreal Formation of central Patagonia, Argentina.
The southernmost records of Rebbachisauridae (Sauropoda: Diplodocoidea), from early Late Cretaceous deposits in central Patagonia
We describe new and redescribe previously discovered sauropod dinosaur material from the Upper Cretaceous (middle CenomanianeTuronian) Bajo Barreal Formation of south-central Chubut Province, central
The pelvic and hindlimb myology of the basal titanosaur Epachthosaurus sciuttoi (Sauropoda: Titanosauria)
This myological description of Epachthosaurus, where twenty one muscles were reconstructed, constitutes useful data for researches interested in functional anatomy and shows several morphological differences which are directly related with the muscular attachments, supporting differences about the musculature arrangement between these two sauropod dinosaurs.
A new ornithopod dinosaur (Dinosauria: Ornithischia) from the Late Cretaceous of central Patagonia
Abstract A new ornithopod dinosaur, the medium-sized Sektensaurus sanjuanboscoi gen. et sp nov. from the Coniacian–Maastricthian strata of the Lago Colhue Huapi Formation, Golfo San Jorge Basin,
