AEOLOSAURUS COLHUEHUAPENSIS SP. NOV. (SAUROPODA, TITANOSAURIA) DE LA FORMACIÓN BAJO BARREAL, CRETÁCICO SUPERIOR DE ARGENTINA

Its presence in the Upper Member of the Bajo Barreal Formation, along with other paleontological records from the same locality, and geologic observations allow us to assign preliminarily a Campanian-Maastrichtian age for the upper levels of this stratigraphic unit outcropping in the southeast of Lago Colhue Huapi, Chubut Province.
