In the present study, selected the Kometan Formation (Late Turonian - Early Campanian) from the Dokan area, NE-Iraq. In this formation studied Ostracoda and identified fifteen open Ostracoda species belonging to ten genera (Bairdia, Bairdiacypris, Bythocypris, Bairdoppilata, Cavellina, Cypridina, Cytherella, Haplocytheridea, Pterygocythereis, and Paracypris). The goal of the present study is to identify Ostracoda species under polarizing microscopes for the first time in the Kometan Formation in the Dokan area. The Ostracoda assemblage such as Bairdia, Bairdiacypris, Cytherella, Cypridina, and Paracypris with foraminifera species Globotruncana linneiana, Globotruncanita stuartiformis, Marginotruncana schneeansi, and Dicarinella asymetrica indicate the Kometan Formation deposited in the deep marine environment.
