The upper cretaceous rocks that are exposed in the Kermanshah area rich in rudist, larger foraminifera and corals. Discoid morphotypes of connolitid corals prevailed during the Tarbur Formation .The absence of costasepta at the basal part of cunnolitid corals shows they were immobile during life and lie freely on the soft substrate. Rudists become the dominant fauna whereas corals disappear. Absence of corals in upper parts of sequence is due to variations in amounts of nutrients. Based on biostratigraphy, Omphalocyclus-Loftusia assemblage zone, was identified.
