The most recent studies reformed the occurrence of Qulqula Conglomerate Formation where they combined with Red Bed Series. The present palaeontological study, in the type locality, aids the recognition of the formation. Twenty species from the three families of Alveolinidae, Soritidae and Nummulitidae are described and figured from the former Qulqula Conglomerate Formation (present Red Bed Series) in Kurdistan Region, Northeastern Iraq. These assemblages indicate the age of the source area as Late Paleocene _ Middle Eocene age. The vertical and lateral distributions of the assemblages are discussed. The pebbles and boulders that bearing the recognized assemblages are derived by erosion from the source area (affiliated to Walash _ Naoperdan Group) and deposited during later ages (younger ages) that more likely they deposited during Late Eocene age

Eighteen plankonic foraminiferal species belonging to five genera have been identified within the studied section of Shiranish Formation in Butmah well no.15; which is divided into four biozones. The first zone represents the Late Campanian age while the other three zones extend within the Early and Middle Maastrichtian age These zones are:
-Gansserina gansseri Zone
-Globotruncana aegyptiaca Zone
- Globotruncanella havanensis Zone
-Globotruncanita calcarata Zone
The age of the studied section in Butmah well no.15 has been fixed as Late Campanian to Middle Maastrichtian while the upper part of the Middle Maastrichtian and the whole Upper Maastrichtian are missing. According to this fact the contact surface between Shiranish and Aaliji Formations is an unconformity surface.

Planktonic foraminifera are studied from Aaliji and Jaddala Formations in East Baghdad Well No.2 between the depth interval 1770-1900 m. Four biostratigraphic zones are recognized in these formations:
Globorotalia (A.) bullbrooki Zone (P.10).
Globorotalia (Morozovella) subbotinae subbotinae Zone (P.7).
Globorotalia (Morozovella) velascoensis Zone (P.5and6).
Globorotalia(Globorotalia)pseudomenardii Zone (P.4).
The results of this study are compared with the work of others inside and outside Iraq. The age of Aaliji in the said well is Late Paleocene - Early Eocene and that of Jaddala is Early – Middle Eocene.
