Sažetak
The nodular limestones exposed at the basal part of the Gebel Hafit
(United Arab Emirates) represent a truncation surface, between the
Rus and the Middle Eocene Dammam Formation (Mibazara Member).
Somalina praestefaninii n.sp. is a new large foraminiferal species
separated from the Mibazara member. It is believed that Somalina
praestefaninii n.sp. is the ancestral form of Somalina stefaninii
Silvestri as it is smaller and has a more simple protoconch. Here,
it is believed that the taxon Somalina (Lutetian) could possibly be
derived from Opertorbitolites NUTTALL , 1925 (the taxon characteristic
for the Ypresian).
