After selected of 50 specimens of coral fossils, from first band of corals, 9 species belong to 5 genera from rugose and tabulae corals with Late Serpukhovian age were identified. These corals are included following species: Heritschioides pseudosolitarius, Heritschioides vepres, Heritschioides cf.vepres, Paraheritschiodes antoni antoni, Paraheritschiodes sp. 1., Paraheritschiodes sp. 2. Multithecopora sp., Orygmophyllum sp. and Durhamina sp. In addition to review of the ages of Heritschioides vepres, H. pseudosolitarius, H. cf.vepres and Praheritschiodes antoni antoni species, two genera including Orygmophyllum and Durhamina are reported for the first time from Iran. These fauna, is similar to Ural, Durhaminidae corals. Based on ecological evidences, corallites arrangement and dissepiments thickness, back-arc parts of a shallow carbonate platform of ramp type can be concluded for the paleoenvironment of our studied section.

The discoveries of Sutherlandia and Thamnoptychia mark the first records of these genera in Iran. This assemblage inhabited on the southern shelves of the Paleotethys along northern margin of Gondwana.

Ten sections were sampled in the Ozbak-kuh Mountains, from north to south. Among the rugose corals, an assemblage of fasciculate Kleopatrinidae has been collected. The latter contains the species: Paraheritschioides antoni antoni, P. antoni minor, P. gracilis and two new species for the genera Fomichevella and Heintzella. Heintzella is described from Iran for the first time. However, its age, as determined by conodonts and foraminifers, is early to middle Bashkirian (early late Carboniferous). The most similar, time-equivalent faunal associations are that of the Ellesmere Island, Sverdrup Basin in Arctic Canada, Alexander terrane and Brooks Range in southeastern Alaska and eastern Klamath terrane in northern California, where similar tropical warm water conditions have been identified during the Bashkirian in the northern hemisphere. During these times central Iran block and Northern provinces, characterized by a dominant carbonate facies and more diversified colonial coral faunas.
