Bassiounina sanctipauli n. gen. n. sp. (Nummulitidae) together with Nummulites praeatacicus n. sp, are newly described from the upper nummulitic bearing sandy marls from Monastery of St. Paul, Eastern Desert, Egypt. According to Schaub’s nummulitic time scale 1981, this interval is assigned to the Early Eocene (Early/Middle Ilerdian), since Nummulites atacicus Leymerie 1846 originally recorded from Mont Cayla (Herault). is a characterisitc species of the top part of the Middle Ilerdian. Nummulites sahariensis n. sp. is also described from a parallel stratigraphic section and is given an Early Eocene Age (Early Ilerdian 1/2); this age is confirmed from studies based on planktonic and benthonic foraminifera and matched well with Schaub’s nummulitic scale. The sediments were deposited in small basins situated on a structural ramp that inclined gently towards the south.
