Calcareous Nannofossils from the Shiranish Formation at Bekhaer anticline, Dhouk area, Northern Iraq

Main Article Content
Abstract
Calcareous nannofossils are examined up on the Shiranish Formation from the Bekhaer anticline in Northern Iraq. The study area includes about 55 meters to find calcareous nannofossils assemblages, from which (36) species have identified.
Three biozones are postulated based on the above studied assemblages, in order of biozones: Tranolithus phacelosus biozone; Reinhardites levis biozone; Arkhangelskiella cymbiformis biozone. From a regional perspective, these biozones were connected with other calcareous nannofossils biozones, leading to the conclusion that the section is Late Campanian-Maastrichtian in age.
