The fossiliferous limestone in the northwest of Iran yields 25 species, 36 genera of Dzhulfian foraminifera consisting of porcelanous forams, uniserial foraminifera, smaller fusulinid, forms of hyaline test assignable to Lagenina suborder and microgranular Biseriamminidae foraminifer. These assemblages are distinguished from thin- bedded limestone, shaly limestone, and marly limestone, which are comparable with the Nesen Formation.
