Fossili cenozoici della Valsugana. Catalogo della "Collezione Boschele", parte II

Cenozoic fossils from Valsugana. Catalogue of the “Boschele Collection”, part II – This second contribution to the description of the Boschele palaeontological collec- tion present a systematic study of ~ 250 specimens, mainly marine invertebrates, found in several stratigraphical levels dating to the early Oligocene. Fossil localities, all located nearby Borgo Valsugana (East Trentino Province), testify to the development of an articulated palaeogeography in the northern sector of the Lessini Shelf. In this context, the corals of the Maso creek described in this catalogue and never documented before, constitute the northernmost discovery so far in the Lessini Platform coral fauna and indicate an environmental evolution that allowed the growth of small but flourishing bioconstructions even in the vicinity of the emergent land. The depositional environment was therefore dominated by terrigenous sedimentation that originated conditions of rather turbid waters.
