ABSTRACT:The paper aims to be a contribution toward the chronostratigraphic definition of the lowermost fossiliferous layer of the San Donato Unit auctt. New data have been collected from the Diplopora beds outcropping Northwest of San Donato di Ninea, between the two highs of Monte Cava dell’Oro and Chianette della Tona. These outcrops have supplied a fossil association with well preserved, semi-isolated calcareous skeletons of dasycladaleans. It has been possible to identify four different taxa: Diplopora annulata, Kanttia monregalensis, Diplopora sp., Gyroporella cf. maxima. The dasycladalean assemblage is a late Anisian - late Ladinia. During this time the carbonate sedimentation began repeacing the silico-clastic deposits with mixed carbonate-siliciclastic facies, which extends until the Carnian (Cornucardia layers).
