Due to high similarities <strong>of</strong> foram<strong>in</strong>iferal occurance, the present Zone (CF5)<br />
is equvalent to that <strong>of</strong> Li <strong>and</strong> Keller (1998a,b), (Abramovich et al., 2002), (Samir<br />
2002) , it is most likely equivalent to the upper part <strong>of</strong> Gansser<strong>in</strong>a gansseri<br />
Zone recorded <strong>in</strong> the North <strong>and</strong> Northeast <strong>of</strong> Iraq <strong>and</strong> different regions <strong>of</strong> the<br />
world (Al-Mutwali <strong>and</strong> Al-Jubouri, 2005), (Al-Mutwali, 1996), (Hammoudi, 2000),<br />
(Caron 1985), (Ubaidalla, 2005), (Robaszynski et al., 1984), (D Hont & Keller,<br />
1991), <strong>and</strong> it is equivalent to the upper part <strong>of</strong> Glt. contusa Zone <strong>of</strong> (Abawi et al.,<br />
1982, <strong>and</strong> Abdel-Kareem, 1986), <strong>and</strong> Glt.contusa-R. fructicosa Zone <strong>of</strong> (Premoli
