First evidence of Hadrosauropodus in Gondwana (Yacoraite Formation, Maastrichtian-Danian), northwestern Argentina
(Pergamon-Elsevier Science Ltd, 2016-10)
Uppermost Cretaceous (Campanian-Maastrichtian) large ornithopod tracks are scarce in Gondwana. This record is limited to few citations in the northern Argentina, Peru and possibly Bolivia, although their ichnological ...
New hadrosaurid (Dinosauria: Ornithopoda) fossils from the uppermost Cretaceous of central Patagonia and the influence of paleoenvironment on South American hadrosaur distribution
(Pergamon-Elsevier Science Ltd, 2021-10)
We describe and incorporate fragmentary new cranial and postcranial materials of hadrosaurid ornithopods into the non-avian dinosaur assemblage of the Upper Cretaceous (Coniacian–Maastrichtian) Lago Colhué Huapi Formation ...
New hadrosaurid remains from the Late Cretaceous of Río Negro Province (Argentina, Late Cretaceous)
(Springer, 2017-06)
Purpose: Although the hadrosaurid record is more abundant in the Northern Hemisphere than in the Southern Hemisphere, it is in Argentina that most remains have been discovered, specifically in Patagonia. This record is ...
Revisiting the hadrosaurid (Dinosauria: Ornithopoda) diversity of the allen formation: A re-evaluation of willinakaqe salitralensis from salitral moreno, Río Negro Province, Argentina
(Asociacion Paleontologica Argentina, 2016-04)
The alpha taxonomic diversity of hadrosaurids in South America is modest compared with that of North America. Currently, it consists of three species: Secernosaurus koerneri Brett-Surman, 1979; Prieto-Márquez, 2010), ...
First endocranial description of a South American hadrosaurid: The neuroanatomy of Secernosaurus koerneri from the Late Cretaceous of Argentina
(Polish Academy of Sciences. Institute of Paleobiology, 2018-09)
The endocranial morphology of Secernosaurus koerneri (= Kritosaurus australis junior synonym), a hadrosaurid from the Upper Cretaceous of Argentina, was studied using latex and digital endocasts based on three fragmentary ...
Ornithischian remains from the Chorrillo Formation (Upper Cretaceous), southern Patagonia, Argentina, and their implications on ornithischian paleobiogeography in the Southern Hemisphere
(Academic Press Ltd - Elsevier Science Ltd, 2021-09)
The fossil record of ornithischians in South America is sparse, and they are clearly underrepresented when compared with sauropod dinosaurs. However, recent discoveries indicate that ornithischians were more diversified ...
