The Appendicular Skeleton of Neuquensaurus, a Late Cretaceous Saltasaurine Sauropod from Patagonia, Argentina
Neuquensaurus, from the Late Cretaceous of Argentina and one of the first dinosaurs described from Patagonia, is one of the most derived sauropod dinosaurs, and its proportions and size place it
A Reappraisal of the Late Cretaceous Argentinean Sauropod Dinosaur Argyrosaurus superbus, with a Description of a New Titanosaur Genus
Argyrosaurus is redescribe, demonstrating it to be a valid titanosaur genus based on five autapomorphies, as well as an unique character combination, which provides new information on this diverse but still poorly understood clade.
Postcranial Anatomy and Phylogenetic Relationships of Mussaurus patagonicus (Dinosauria, Sauropodomorpha)
The postcranial anatomy of four specimens of basal sauropodomorphs from the Late Triassic of Patagonia, Argentina are described and identified as adult individuals of Mussaurus patagonicus, which is recovered as a non-sauropod anchisaurian and is depicted outside the ‘quadrupedal clade’.
A new giant titanosaur sheds light on body mass evolution among sauropod dinosaurs
A new giant titanosaur is described, which represents the largest species described so far and one of the most complete titanosaurs, and its inclusion in an extended phylogenetic analysis and the optimization of body mass reveals the presence of an endemic clade of giant titanosaurs inhabited Patagonia between the Albian and the Santonian.

The ultimate goal of this contribution was to provide an exhaustive guide to muscular identification in fossil archosaurs and to offer solid anatomical bases for future studies based on osteology, myology, functional morphology and systematics.
Temporal and phylogenetic evolution of the sauropod dinosaur body plan
Three-dimensional computational models and phylogenetic reconstructions are combined to quantify the evolution of whole-body shape and body segment properties across the sauropod radiation, finding that relative neck size and CoM position are not strongly correlated with inferred feeding habits.
Pelvic musculature and function of Caiman latirostris
The musculoskeletal hindlimb anatomy of the alligatorid Caiman latirostris Daudin is presented. The description includes origin and insertion sites as well as anatomical function of the pelvic and
Ontogenetic changes in the body plan of the sauropodomorph dinosaur Mussaurus patagonicus reveal shifts of locomotor stance during growth
This study indicates that relative development of the tail and neck was more influential in determining the locomotor stance in Sauropodomorpha during ontogeny, challenging previous studies, which have emphasized the influence of hindlimb vs. forelimb lengths on sauropodomorph stance.
A new sauropod titanosaur from the Plottier Formation (Upper Cretaceous) of Patagonia (Argentina)
This paper presents a new titanosaur sauropod, collected from levels of reddish clays assigned to the Plottier Formation (Coniacian-Santonian). The holotype of Petrobrasaurus puestohernandezi gen.
Forelimb muscle and joint actions in Archosauria: insights from Crocodylus johnstoni (Pseudosuchia) and Mussaurus patagonicus (Sauropodomorpha)
This work presents biomechanical computer models of two locomotor extremes within Archosauria and evaluates in which ways forelimb posture was correlated with muscle leverage, and how such differences fit into a broader evolutionary context.
