Abstract
      Devonian corals of Bahram Formation in Cheshme Shir area (South of Osbak-kuh) were studied. In the study section, more than 18 species belonging to 10 genera of Rugose corals were identified. The following genera are: Sinodisphyllum, Spinophyllum, Glossophyllum, Acantophyllum, Temnophyllum, Cystihexagonaria, Marisastrum, Hexagonaria, Ceratophyllum and Pseudozaphrentis, which suggest an Upper Givetian-Frasnian age.
According to coral morphology, 2 assemblages were distinguished. The first assemblage occurs in the reef areas and is composed of colonial corals forming patch reefs. The second assemblage is composed of dissepimented corals of median size that occurs in shallow water of an open shelf.
