          Abstract

          Abstract Additions are offered to the diverse estuarine, freshwater and terrestrial gastropod fauna of the Upper Cretaceous (Campanian) and Paleocene lithostratigraphic units of the Difunta Group, NE México (Coahuila and Nuevo León). Nineteen species of continental gastropods (five of them new) are reported and illustrated from the upper Campanian Cerro del Pueblo Formation (Las Águilas/Porvenir de Jalpa locality) and the Paleocene Las Encinas Formation (La Leona locality), northern Parras Basin, Difunta Group, Coahuila. The first record of pulmonate gastropods from the Difunta Group is based on several specimens of different species. This is the third contribution dealing with these continental gastropods from the study region and a revised list of reported species is presented. Although we follow the most recent classification of continental gastropods, we also base the identification on paleontological systematics, knowing that some important diagnostic features were not preserved. Thus, we do not intend to propose paleobiogeographic or evolutionary inferences. Our main goal is to present the paleodiversity known from the study area, in hope that these data would be useful for more detailed studies in the near future.

          Resumen Se ofrecen adiciones a la diversa fauna de gastrópodos estuarinos, dulceacuícolas y terrestres de las unidades litoestratigráficas del Cretácico Superior (Campaniano) y Paleoceno del Grupo Difunta, NE de México (Coahuila y Nuevo León). Diecinueve especies de gastrópodos continentales (cinco de ellas nuevas) son reportadas e ilustradas para la Formación Cerro del Pueblo del Campaniano superior (localidad Las Águilas/Porvenir de Jalpa) y la Formación Las Encinas, del Paleoceno (localidad La Leona), porción norte de la Cuenca de Parras, Grupo Difunta, Coahuila. El primer registro de gasterópodos pulmonados para el Grupo Difunta, se basa en varios ejemplares de diferentes especies. Esta es la tercera contribución que trata sobre caracoles continentales de la región y se presenta una lista revisada de especies. Aunque seguimos la más reciente clasificación de gasterópodos continentales, también basamos la identificación en sistemática paleontológica, concientes de que algunas características diagnósticas importantes no fueron preservadas. Por lo tanto, no intentamos proponer inferencias evolutivas o paleobiogeográficas. Nuestro propósito principal es presentar la paleodiversidad conocida para el área de estudio, en espera de que pueda ser de utilidad para estudios más profundos a futuro.
