As ostracods are excellent index in determining the paleoenvironment, age and paleoecology of sediments, the ostracods in marls units 1 and 3 of Tarbur Formation have been studied. Tarbur Formation with 712 m thickness is divided into 6 units. In this study, 60 samples of marls units 1 and 3 have been washed, and studied and totally 21 species identified. The ostracods indicate a Maestrichtian age and warm, oxygen-rich and shallow depositional environment for the studied units.
