| dc.description.abstract | An ammonite fauna from an isolated outcrop of the Upper Jurassic Vaca Muerta Formation is described from Barda Negra in the southern part of the Neuquén-Mendoza Basin. It comprises several macroconch specimens of the species Aspidoceras cf. euomphalum Steuer, 1897 besides macroconchs and microconchs of Windhauseniceras internispinosum (Krantz, 1926), the index species of the Andean Middle Tithonian Internispinosum Zone. Morphological and taxonomic relationships of the studied aspidoceratids with previously described species and the sexual dimorphism in W. internispinosum are discussed. | en_US |

Se describe una fauna de amonites colectada en un afloramiento aislado de la Formación Vaca Muerta en Barda Negra, en la parte sur de la Cuenca Neuquén-Mendoza. Esta fauna comprende especímenes de Aspidoceras cf. euomphalum Steuer, 1897 y macroconchas y microconchas de Windhauseniceras internispinosum (Krantz, 1926), la especie índice de la Zona Internispinosum del Tithoniano Medio andino. Se discuten las relaciones morfológicas y taxonómicas de los aspidocerátidos estudiados con las especies previamente descriptas y el dimorfismo sexual de W. internispinosum. | en_US |
