ABSTRACT
In this contribution, a fossil tooth assemblage from the Bajo de la Carpa Formation (Santonian, Upper Cretaceous) in a different paleoenvironmental context from that recorded at the Neuquén city and Paso Córdova localities (Patagonia, Argentina), is here presented. It includes isolated teeth of Dipnoi, represented by the species Ceratodus kaopen and Atlantoceratodus patagonicus; mesoeucrocodylian isolated teeth referred to Peirosauridae; and isolated teeth of Abelisauridae theropods and Titanosauria sauropods. The Mesoeucrocodylia, Albelisauridae and Titanosauria taxa are consistent with the fossil record of the region, represented by the Coloradon tetrapod assemblage of Santonian to early Campanian age. However, the lungfish A. patagonicus represents the first occurrence for the Bajo de la Carpa Fromation, being this record the oldest one for this taxon.
Keywords: Dipnoi, Mesoeurocrocodyla, Abelisauria, Titanosauria, Upper Cretaceous, Patagonia.
