Resumo: | This paper describes several fossil teeth coming from marine sediments from the Bajo Trapalcó locality, Río Negro province, Patagonia, Argentina. The ichthyofauna described here is composed by six different chondrichtyan taxa (Serratolamna serrata, Squalicorax pristodontus, Cretalamna appendiculata, Carcharias sp., Odontaspis sp. and cf. Pseudohypolophus mcnultyi) and two Teleostei of the genus Enchodus (aff. E. ferox and aff. E. gladiolus). Serratolamna serrata is the most abundant species, and it represents the southernmost record for the species and the first record for Argentina. The records of Enchodus, Squalicorax pristodontus and cf. Pseudohypolophus mcnultyi, constitute the first mention for these taxa in Argentina. The taxa described here characterize the paleoichthyofaunas of the Upper Cretaceous seas from different regions of the world, contributing with new information toward the comprehension of the Mesozoic ichthyofunas from the southern regions of South America. |

Se describe un conjunto de dientes fósiles que proceden de sedimentos marinos de la Formación Jagüel (Maastrichtiano), de la localidad de Bajo Trapalcó, provincia de Río Negro, Patagonia, Argentina. La ictiofauna aquí descripta es la primera para la Formación y se compone de unos seis taxones diferentes de Chondrichthyes (Serratolamna serrata, Squalicorax pristodontus, Cretalamna appendiculata, Carcharias sp., Odontaspis sp. y cf. Pseudohypolophus mcnultyi) y dos Teleostei del género Enchodus (aff. E. ferox y aff. E. gladiolus). Serratolamna serrata es el taxón mejor representado del conjunto, y constituye la cita más austral conocida en la distribución de esta especie y el primer registro fósil para Argentina. Los registros de Enchodus, Squalicorax pristodontus y cf. Pseudohypolophus mcnultyi, representan las primeras descripciones de estos taxones para Argentina. Todos los taxones descriptos constituyen un ensamblaje de especies que caracterizan las paleoictiofaunas de los mares del Cretácico Superior de distintas partes del globo, aportando novedosa información para la comprensión de las ictiofaunas Mesozoicas del cono sur sudamericano.
