Rugosa (Anthozoa) of the Serpukhovian from the Upper Silesian Coal Basin

Jerzy Fedorowski, Iwona Machłajewska


Two species, Antiphyllum sp. nov. 1 and Zaphrufimia sp. nov. 1, the first corals found in Štur horizon of the upper Malinowickie Beds, Upper Pendleian (E1), are here described. Additional study of the subspecies of Zaprufimia disjuncta show them to be more similar than previously thought. Although they occur mainly in the Enna and Barbara horizons, one specimen of Z. d. serotina comes from the Gabriela horizon. Biozone Zaphrufimia disujncta disjuncta/Z .d .praematura is proposed for the Enna and Barbara horizons. The subzone of Zaphrufimia/Triadufimia of that Biozone, defined by the presence of Triadufimia gen. nov., is restricted to the Enna horizon. As confirmed by the occurrence of Cravenoceratoides edalensis, the new subzone roughly corresponds to the E2b1 ammonite Zone. An Antiphyllum  Ostravaia/Variaxon assemblage Zone is proposed for the coral assemblage of the Gaebler horizon. Cravenoceratoides nitidus present in the Roemer band (Ib) shows it to correlate with the E2b2 ammonite Zone. Comparison with other European regions suggests possible faunal exchange between those areas and the Upper Silesian Coal Basin in Serpukhovian time.
