| The main aim of this research is study of the planktonic foraminifera morphogroups distinction genus to perform by changing the umbilicus area in Ziarat-kola section to find novel results. Therefore, original objection at this research considers the cause of organizing umbilicus structures (Lip, Portici, Tegilla) at this protests. it seems that phylogeny trend entirely the changes of planktonic foraminifera changing from lip at primary morphogroup to tegilla at development shape which continued this phylogeny trend opening become entirely umbilicus that this trend accompanied to increasing deep. Therefore, the study of planktonic foraminifera morphotype, and recognizing, the obtained results from planktonic foraminifera analysis percent and their... |
