CAVOLINIDAE DEL MIOCENE INFERIORE Dl CASTELSARDO (SARDEGNA SETTENTRIONALE)

Abstract

In this paper are described and illustrated Pteropoda coming frorn two Lower Miocene sections exposed near the village of Castelsardo (Norhern Sardinia). The sampled sections cover a stratigraphic range which extends from the basal part of zone N4 to uppermost N6 (after Blow's planktonic foraminiferal zonation), that means an Aquitaman—Burdigalian age.
