Maastrichtian and Selandian decapod crustaceans from Sardinia

Two decapod crustaceans, Protocallianassa cf. faujasi (Desmarest, 1822) and Titanocarcinus cf subellipticus (Segerberg, 1900), of Maastrichtian and Selandian age respectively, are described from eastern Sardinia. They were found within clasts of a conglomerate (Cuccuru 'e Flores Conglomerate) of middle Lutetian age. This presence in Sardinia of taxa assimilable to species till now known exclusively, and in large number of individuals, in NW Europe allows to confirm faunistic exchanges between the Boreal Sea and Tethys ocean, at least intermittently, during Late Cretaceous and Early Tertiary. The most characteristic foraminifers accompanying the Maastrichtian decapod are figured; they supply evidence of a sedimentary facies no more cropping out in Sardinia.
