Litavkaspis rejkovicensis Fatka, Kordule et Šnajdr from the Příbram-Jince Basin has been known to occur in a roughly 30 m thick eponymous Taxon-range Zone situated in the lower parts of the Jince Formation (Cambrian, Drumian), within the Eccaparadoxides pusillus Interval Zone. A unique finding of a cranidium of Litavkaspis sp. at the locality Jince-Vystrkov, described in this report, comes from the middle parts of the Paradoxides gracilis Taxon-range Zone, lying roughly 250 m higher than the hitherto known biostratigraphically youngest occurrence of the index taxon. Specimens of Dawsonia bohemica (Šnajdr) from the Jince Formation have been collected exclusively in about 1 m thick deposits of the eponymous Taxon-range Zone situated stratigraphically at the base of the Onymagnostus hybridus Interval Zone. The findings of Dawsonia cf. bohemica presented herein come from the localities Rejkovice – Potůček in the Litavkaspis rejkovicensis Taxon-range Zone, and Rejkovice – Ve žlutých in the Acadolenus snajdri Interval Zone. Their stratigraphic positions are therefore 30–50 m lower than the typical occurrence of Dawsonia bohemica (Šnajdr) in the eponymous Taxon-range Zone.
