Abstract


Twenty-two conodont species are recognized in the Ockerkalk exposed in the Silius area (Gerrei, southeastern Sardinia). The fauna, which is the first reported from this peculiar facies, indicates a Ludlow and e.-m. Pridoli age for this limestone. Three conodont biozones (latialata, snajdri and crispa) are reported for the first time in Sardinia and, the Pelekysgnathus index horizon is newly recovered in Europe.

Keywords
