Distribution of the bivalve species Tanchintongia ogulineci in Velebit

Abstract

Tanchintongia ogulineci was determined 1978 from the 2^nd limestone zone of the Permian Velebit carbonate series. Beside the type locality some other occurrences were found now in the same rock as well as in a dark gray, white-dotted dolomite variety. The limestone belongs to the Upper Kungurian stage, while the stratigraphic range of the dolomite is Upper Artinskian-Lower Kungurian. Different fossiliferous zones could be distinguished in the dotted dolomite. A sponge-reef and a new brachiopod occurrence have been found in the 2^nd zone of Parmian limestone, otherwise also designated after Neoschwagerina craticulifera.
