The nodular limestones exposed at the basal part of the Gebel Hafit(United Arab Emirates) represent a truncation surface, between theRus and the Middle Eocene Dammam Formation (Mibazara Member).Somalina praestefaninii n.sp. is a new large foraminiferal speciesseparated from the Mibazara member. It is believed that Somalinapraestefaninii n.sp. is the ancestral form of Somalina stefaniniiSilvestri as it is smaller and has a more simple protoconch. Here,it is believed that the taxon Somalina (Lutetian) could possibly bederived from Opertorbitolites NUTTALL , 1925 (the taxon characteristicfor the Ypresian).
