Abstract (in english)
   Numerous graptoloid specimens have been discovered and identified in a large olistolith of Silurian black shales and lydites situated within the Culm-type Hercynian Sulcis flysch complex of SW Sardinia. The graptolite fauna discovered at Punta SŽOmu de Is Abis (Sulcis area) is attributable to the middle spiralis ů lower lapworthi biozones of the upper Llandovery. Of nine species recorded, Stomatograptus grandis, Monoclimacis geinitzi, Diversograptus ramosus, ?Cyrtograptus lapworthi, Oktavites excentricus and 'Monograptus' aff. nodifer have been recognized for the first time in Italy. Using the specimens from Punta SŽOmu de Is Abis and topotypic material from Bohemia, Stomatograptus grandis (Suess, 1851) is revised and its stratigraphical range re-evaluated.
