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. Specifically, the specimen was recovered from the uppermost Cretaceous (Campanian—?Maastrichtian) Upper Member of the Bajo Barreal exposed on an ephemeral island in the southeastern portion of Lago Colhué Huapi in southern Chubut Province. Identifiable elements of the skeleton include four incomplete… 

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.

A New Peirosaurid Crocodyliform from the Upper Cretaceous Lago Colhué Huapi Formation of Central Patagonia, Argentina

Colhuehuapisuchus constitutes the southernmost peirosaurid occurrence worldwide and arguably the youngest record from Patagonia, thereby expanding the paleobiogeographic range of these distinctive mesoeucrocodylians to nearly the end of the Mesozoic and the southern tip of South America.

Osteology of the Patagonian ornithopod Talenkauen santacrucensis (Dinosauria, Ornithischia)

Feature of the cervical series of Talenkauen, which are shared with other elasmarians, indicate that these dinosaurs have a proportionally longer neck than other ornithopods, and indicates that Elasmaria was distributed more widely geographically and temporally than previously thought.

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.

Aniksosaurus darwini gen. et sp. nov., a new coelurosaurian theropod from the Early Late Cretaceous of Central Patagonia, Argentina

Comparisons with maniraptoriforms support that Aniksosaurus is less derived than these theropods and suggests that the new Patagonian taxon is more derived than some basal coelurosaurians such as compsognathids, Ornitholestes, and coelurids.

NOTES ON THESCELOSA UR US, A CONSERVATIVE ORNITHOPOD DINOSAUR FROM THE UPPER CRETACEOUS OF NORTH AMERICA, WITH COMMENTS ON ORNITHOPOD CLASSIFICATION

The skull of Thescelosaurus had broad frontals and there is a well-defined area of attachment for a cheek on the mandible, which are primitive for ornithopods (and ornithischians as a group) but this genus was probably graviportal and possibly even more quadrupedal than most other ornithsopods.

Osteology and phylogeny of Zalmoxes (n. g.), an unusual Euornithopod dinosaur from the latest Cretaceous of Romania

A phylogenetic analysis of basal euornithopods indicates that the non‐hadrosaurid material from Hateg comprises two distinct, but congeneric, species, and indicates the recognition of a ghost lineage, extending from the most recent common ancestor of Rhabdodontidae and Iguanodontia, which extends for 73 million years.
