The Silurian exposed in southwestern Sardinia is well-known for its precious faunal content. Lower part of the sequence consists of black graptolitic shales (Genna Muxerru Formation) comprising much of the Llandovery. It is suceeded by a calcareous unit (Fluminimaggiore Formation), locally rich in cephalopods, covering the rest of the Silurian. Even the Lower Devonian is represented by limestones. A precise and detailed biostratigraphical assignment of the units has been achieved by graptolites and conodonts.

Abstract
The Silurian exposed in southwestern Sardinia is well-known for its precious faunal content. Lower part of the sequence consists of black graptolitic shales (Genna Muxerru Formation) comprising much of the Llandovery. It is suceeded by a calcareous unit (Fluminimaggiore Formation), locally rich in cephalopods, covering the rest of the Silurian. Even the Lower Devonian is represented by limestones. A precise and detailed biostratigraphical assignment of the units has been achieved by graptolites and conodonts.
