Smaller foraminifers from the Permian of Central Iran

Six assemblages of smaller foraminifers are first distinguished and described from sections of the Kalmard tectonic block, Central Iran. The assemblages that have been studied are correlated with concurrent assemblages from the East European platform, Cis-Urals, Darvaz, Northern Pamir, and some other regions of the Tethyan Realm. The results of correlation and available data on fusulinids and conodonts occurring in association with smaller foraminifers are used for dating the assemblages whose distribution ranges span the stratigraphic interval from the early Sakmarian (lower assemblage) up to the Kubergandian (uppermost assemblage). New species Frondina iranica sp. nov. discovered in the study region is described.
