Abstract
Smaller foraminifers from the Chili Formation recovered in the Rahdar section of the Kalmard tectonic block west of Tabas, Central Iran, are studied. Two smaller foraminiferal assemblages whose position in the section completely coincides with that of previously encountered Kalaktash and Halvan fusulinid complexes are recognized. The age of these Deckerella elegans-Nodosinelloides pinardae and Howchinella sossipatrovae assemblages is Sakmarian and late Sakmarian-early Artinskian (?), respectively. A new species Hemigordius rahdarensis Filimonova, sp. nov. is described.
