Planktonic foraminifera are described for the first time from the Senonian
sediments on the Calabar Flank, southeastern Nigeria.
The species described belong to the family Heterohelicidae Cushman and they
were all recovered from the Nkporo Shale. Three of them, Heterohelix calabarflanki
n. sp., Heterohelix ivandeklaszi n. sp., and Heterohelix nkporoensis n. sp.
are new.
The Nkporo Shale sediments on the flank have hitherto been considered Senonian
in age solely on the basis of the formation's stratigraphic position. The
Heterohelicid foraminiferal assemblage provides the first conclusive evidence for
this age indicating a Santonian-Campanian age for the lower part of the formation.
