The study of the umbilical system in planktonic foraminifera in relation with depth of the Abderaz Formation at type section, IRAN

Prospect of changes in such umbilical structures as Lip, Portici and Tegilla throughout Turonian-Campanian was also investigated. The phylogenic trend show that Lip structure in primary morphogroups turns gradually to tegilla in more developed forms in which the opening become also entirely umbilica...
