The Paleocene-Early Eocene Foraminiferal Biostratigraphy Of Eastern Dahomey Basin, Sw Nigeria
Full Text(PDF, )  PP.  
Okosun, E. A. and Alkali, Y. B
The foraminiferal biostratigraphy of the Paleocene - early Eocene strata of SW Nigeria which represents the eastern Dahomey basin has been studied from four boreholes and two outcrops. A fairly diverse planktic and benthic foraminiferal assemblage was rec
