The radiolarites of the Saris and Pieniny part of the Pieniny Klippen Belt belong to the Pieniny Succesion s.l. (Nemcok et al. l990). A horizon of radiolarites from the locality Milpos and Podsadek near Stara Lubovna contains a considerable calcareous admixture. At the localities of Sarisske Jastrabie and Lucka the radiolarites are almost without calcite and contain Mn coatings. The radiolarian associations represent UAZone 8 - UAZone l0 ranging from middle Callovian to early Kimmeridgian (sensu Baumgartner et al. l995). Radiolarites with Mn coatings reach to middle Oxfordian at the locality Sarisske Jastrabie. A new genus Fultacapsa nov. gen. is described in this paper.
