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, Abelisauridae and Titanosauria taxa are
consistent with the fossil record of the region, represented by the Coloradoan tetrapod
assemblage of Santonian to early Campanian age. However, the lungfish A. patagonicus represents the first
occurrence for the Bajo de la Carpa Formation, being this record the oldest one for this taxón.
