Paleoenvironment of the Late Cretaceous (Late Touronian-Early Campanian) Ostarcoda in the Kometan Formation, Dokan Area, Kurdistan region, NE-Iraq

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.

Automated summary

In this study, the researchers identified fifteen open ostracoda species belonging to ten genera in the Kometan Formation in the Dokan area of NE-Iraq. The presence of certain ostracoda species and foraminifera species indicates that the Kometan Formation was deposited in a deep marine environment.
