Abstract

To study the Paleoecology of Oligo – Miocene Ostracods in north east of Sirjan, a suitable section has been measured and sampled. 12 genera of ostracods have been identified and are reported for the first time from this area. The specimens are well – preserved and both platycopids and podocopids are present. The assemblage consists of Aurila spp., Actinocythereis, Baidoppilata, Bairdia, Cytherideis, Propontocypris, Henryhowella, Krithe spp., Paradoxostoma, Trachyleberis, Tenedocythere, Xestoleberis, Cytherella, and Cytherelloidea. Constituents of  this assemblage of ostracods community confirm a favorable condition during the deposition of the strata, specially well-oxygenated environment. These ostracods and associated foraminifers are representing an Early Miocene age for this succession.
