dc.description.abstract The late Turonian ammonoid fauna of Rochefort-en-Valdaine (Drôme, France) is herein described in detail and the intraspecific variability of Vocontiiceras vocontiense Diebold et al., 2018, is studied. The ammonoid assemblage (9 taxa identified) was deposited within the Prionocyclus germari Zone, which was defined in Germany, and is now also documented in southeastern France. Moreover, the co-occurrence of the heteromorph ammonoids Hyphantoceras (Hyphantoceras) flexuosum (Schlüter) and Hyphantoceras (Hyphantoceras) ernsti Wiese indicates the lower part of the Prionocyclus germari Zone. en
dc.description.abstract La faune d'ammonites du Turonien supérieur de Rochefort-en-Valdaine (Drôme, France) est décrite en détail et la variabilité intraspécifique de Vocontiiceras vocontiense Diebold et al., 2018, est étudiée. Cette faune d'ammonites (9 taxons identifiés) est caractéristique de la Zone à Prionocyclus germari, préalablement définie en Allemagne, et dont la présence est maintenant démontrée dans le sud-est de la France. De plus, la présence des ammonites hétéromorphes Hyphantoceras (Hyphantoceras) flexuosum (Schlüter) et Hyphantoceras (Hyphantoceras) ernsti Wiese indique plus précisement la partie inférieure de la Zone à Prionocyclus germari. fr
