Sažetak
The first recovery of the conodont H. parvus from Slovenia a few years ago highlights Slovenian for the Early Triassic conodont biostratigraphic study. Systematic sampling of the Mokrice section and five sections in the Idrija–Žiri area has resulted in the discovery of new species: Platyvillosus corniger sp. nov. and Neospathodus planus sp. nov. Based on these new species and other conodont elements obtained from these sections, a unique conodont sequence is proposed for the Slovenian Early Triassic. It composes of ten conodont zones that span from the Uppermost Dienerian (Upper Induan) to the Lower Spathian (Lower Olenekian). In ascending order, they are: Eurygnathodus costatus Zone, Neospathodus planus Zone, Neospathodus robustus Zone, Foliella gardenae-Pachycladina obliqua Zone, Hadrodontina aequabilis Zone Platyvillosus corniger Zone, Platyvillosus regularis Zone, Triassospathodus hungaricus Zone, Triassospathodus symmetricus Zone, Neospathodus robustispinus Zone. This conodont sequence is valuable for stratigraphic correlation within Central and South Europe, and it also promotes a better correlation between western and middle-eastern Tethys. A global comparison with conodonts indicates that the unique conodont sequence in Slovenia seems to have been more controlled by the ecological parameters of the epeiric ramp than by potential migration barriers. Multielement conodont apparatuses of Triassospathodus hungaricus and Platyvillosus regularis have been constructed based on conodont elements which are obtained from the Mokrice and Žiri-sortirnica 28 sections. Though S2 element was not found, the apparatus indicates “Spathognathodus” hungaricus should be assigned to the genus Triassospathodus.
