description 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.
