A surface section of Jaddala Formation was studied near Bara Village in the western plunge area of Sinjar anticline northwestern Iraq . The sequences consist of marl, marly limestone and limestone beds. Detailed study of planktonic foraminifera revealed (38) species belonging to (14) genera; the stratigraphic distribution of these species permits the regognition of five zones; these are: Morozovella aragonensis Zone, Acarinina pentacamerata Zone, Acarinina bullbrooki Zone, Globigerinatheka subconglobata Zone and Acarinina collactea Zone. These zones indicate that Jaddala Formation is of Early - Middle Eocene age.
