This study focuses on the lower Aptian desmoceratid fauna of Oliete sub-basin (Teruel province). The systematic revision of these biostratigraphy well constrained ammonites, allowed us to work on two issues. On the fist place, we improved the systematic and taxonomic knowledge about Pseudosaynella raresulcata (d’Orbigny, 1841), Pseudosaynella bicurvata (Michelin, 1838) and Pseudohaploceras liptoviensis (Zeuschner, 1856) whose definitions, previous to this study, were based on scarce material and few studies on their ontogenetic variation. On a second place, we constrained their stratigraphical ranges, especially for the Pseudosaynella species, and their correlation with the lower Aptian standard ammonite Mediterranean zonation.Downloads
