(Servicio Publicaciones, 2015-03-20)
In recent years a rich and diverse fauna of hadrosaurid dinosaurs has been described in the Upper Cretaceous of the Pyrenees. Recent<br />fieldwork carried out in the upper Maastrichtian levels of the Tremp Formation, in ...
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 ...
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 ...
Bonapartesaurus rionegrensis, a new hadrosaurine dinosaur from South America: implications for phylogenetic and biogeographic relations with North America
(Society of Vertebrate Paleontology, 2017-03)
The Gondwanan hadrosaurid dinosaur record is relatively poorly known and very complicated. A new hadrosaurid, Bonapartesaurus rionegrensis, gen. et sp. nov., from the late Campanian–early Maastrichtian of the Salitral ...
