Abstract
A high-resolution study of sediments from DSDP Leg 72 Site 516 provided the opportunity to reconstruct a detailed biostratigraphy for the late Oligocene - early Miocene time interval. The detailed taxonomic investigation of calcareous nannofossils, performed by a quantitative analysis, highlighted the presence of a species of Pontosphaera that does not show the morphologic features of any recognized species of this genus. This species, which was previously classified as Pontosphaera sp., is here described as Pontosphaera wallacei nov. sp.
