| Abstract | ||
| Fifteen samples from the lower part of Shiranish Formation, Sinjar anticline, northwest Iraq, are investigated in order to identify calcareous nannofossils species of which twelve species are recorded as follow; one species of holococcoliths, seven are heterococcoliths and four are nannolith. On the basis of the above assemblages two biozones are proposed from oldest (at bottom) to youngest (at top): 2- Tranolithus phacelosus Interval Zone(Part) (CC23) 1- Lithraphidites praequadratus Partial Zone(Part) (CC22) The above biozones are correlated with other calcareous nannofossils biozones from regional view led to conclude that the section is late Campanian in age. | ||
