In the dusk of Mesozoic, advanced duck-billed dinosaurs (Hadrosauridae) were so successful that they likely outcompeted other herbivores, contributing to declines in dinosaur diversity. From Laurasia, hadrosaurids dispersed widely, colonizing Africa, South America, and, allegedly, Antarctica. Here, we present first species a from subantarctic region, Gonkoken nanoi, early Maastrichtian age Magallanes, Chile. Unlike duckbills further north Patagonia, descends North American forms diverging...
Se describe a Magallanodon baikashkenke gen. et. sp. nov., un nuevo mamífero gondwanaterio del Cretácico tardío de la Región Magallanes, en el sur Chile (Valle Río Las Chinas, Estancia Cerro Guido, norte Puerto Natales, Provincia Última Esperanza). capas portadoras se ubican entre los niveles Campaniano tardío-Maastrichtiano temprano Formación Dorotea (Cuenca Magallanes/Austral). Los nuevos restos constituyen registro más austral Mesozoico, como así también primer Mesozoico conocido para...
This study presents the first plesiosaurs recovered from Jurassic of Atacama Desert that are informative at genus level. One specimen is represented by an articulated axial section shows distinctive features, such as cervical vertebrae with oval articular facets and gracile neural pedicles. The second preserves similar vertebrae, teeth, propodials, pectoral elements. Their anatomical characteristics allow us to refer them Muraenosaurus, a cryptoclidid plesiosaur previously reported in...

Abstract In the dusk of dinosaur era, advanced duck-billed dinosaurs (Family Hadrosauridae) are thought to have outcompeted other herbivores, making ecosystems less diverse and more vulnerable Cretaceous-Paleogene asteroid impact. They were also among first terrestrial organisms disperse from North America into South America. Here, we present new species subantarctic dinosaur, CPAP 3054, early Maastrichtian age in Magallanes, Chile. Surprisingly, unlike duckbills further north Patagonia,...
Abstract Armoured dinosaurs are well known for forms that evolved specialized tail weapons: paired spikes in stegosaurs, and heavy clubs advanced ankylosaurs1. from southern Gondwana rare enigmatic, but likely include the earliest branches of Ankylosauria2-4. Here, we describe a mostly complete, semiarticulated skeleton small (about 2m) armoured dinosaur late Cretaceous Magallanes southernmost Chile, region biogeographically related to West Antarctica5. Stegouros elengassen gen. et sp. nov....
