South American Dinosaurs

As a result of continuing fieldwork in the Mesozoic of Patagonia (Argentina) and collaborative work with Research Associate Rodolfo Coria (Museo Municipal Carmen Funes, Plaza Huincul), we have developed a productive research program aimed at studying the diversity and evolution of Mesozoic dinosaurs (including birds) in Argentina, home of the richest dinosaur localities of South America. The recognition of new species and the study of the physical characteristics of the dinosaurs that inhabited this part of the world are some of the main objectives of this program. Our program also aims to understand the transformations that occurred in the dinosaur faunas of Patagonia during the last 25 million years of Mesozoic history.
