Sauropod diversity (Dinosauria: Sauropoda) of Cerro Overo – La Invernada (Bajo de la Carpa Formation, Santonian), northeastern Neuquén Basin, and paleoecological implications for Upper Cretaceous sauropod faunas

The Upper Cretaceous fossil vertebrate fauna of the Bajo de la Carpa Formation (Santonian), derived from several different locations in the Neuquén Basin, is relatively abundant and diverse, comprising mainly small to medium-sized reptiles, birds and fishes. The Cerro Overo – La Invernada locality (...

La fauna de vertebrados fósiles del Cretácico Superior proveniente de la Formación Bajo de la Carpa (Santoniano) de diferentes localidades de la Cuenca Neuquina, es relativamente abundante y diversa; está compuesta principalmente por formas de reptiles, aves y peces de pequeño y mediano tamaño. La localidad de Cerro Overo – La Invernada (CO – LI), en el norte de la cuenca, registra para dicha edad, un componente faunístico similar, pero destacándose por una abundancia y diversidad relativamente mayor de saurópodos titanosaurios. El estudio de los materiales presentados aquí permite establecer la presencia de especímenes de saurópodos diferentes a Overosaurus, el único titanosaurio registrado hasta el momento en el área, y la coexistencia de formas de pequeño-mediano tamaño con formas más grandes, que representan a su vez algunas formas con características más basales y otras con rasgos más derivados. La abundancia del registro de saurópodos en CO – LI muestra variaciones tanto morfológicas como evolutivas, por lo que el hallazgo de ejemplares más completos permitirá llevar adelante estudios paleofaunísticos, paleobiológicos y paleoecológicos. Esto brindará una mejor comprensión del papel de los saurópodos titanosaurios en los ecosistemas del Cretácico Superior.
