Introduction: Foraminifera are testate, single-celled eukaryotic, protozoan’s and are one of the most abundant microfossils found in marine sediments and other depositional settings. The Rya Formation has provided fossils of a number of sharks , ammonites , bivalves and ichnofossils . The utility of benthic foraminifera in bathymetric interpretation of clastic depositional environments is well established. All larger benthic foraminifera (LBF) are marine and neritic and live in oligotrophic reef and carbonate shoal environments (BouDagher-Fadel, 2008).

We can study foram assemblages as paleobiological communities, which can inform us about the ancient ocean-climate system, depositional environment, biotic response to global change, and patterns of evolution. Paleoenvironmental analysis is the interpretation of the depositional environment in which the rock unit formed, based upon the fossils found within the unit. A total number of 35 samples were collected from a 30 m thick quarry section and used to prepare 35 thin sections.
