Oligosteginid (calcispheres ) assemblages which found in Dokan Formation, Erbil Governorate, Kurdistan Region, have a stratigraphic distribution similar to that found in Bangestan Group (Albian-Campanian) of Lurestan Province, Iran. Ten rock samples were collected from Ismael Awa section, Dokan formation and 20 thin sections were made and studied under microscope. There are five oligosteginid species found in Dokan Formation and all these species are of Late Albian, the depositional environment of the formation is tropical to subtropical, warm water 30-32 ◦ C on the continental slope to abyssal zone and paleosalinity between 34-37 ‰. key words: oligosteginid, calcisphere, Albian, Dokan. لامش ,ناتسدرك ميلقا ,هوآ ليعامسا عطقم يف يضوحلا يريجلا رجحلا عباتتل دنجتسوجيلولاا تاعمجت قارعلا
