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.
