• One specimen of Neithea could be Neithea cf. shawi Pervinquiere (= N. coquandi Peron). The distribution of N. shawi is Albian-Cenomanian in the Angola Basin but mostly Cenomanian in northern Africa. This specimen is, however, poorly preserved and could belong to the species N. regularis Schlotheim. In Europe the distribution of N. regularis Schlotheim ranges from Turonian to Senonian. Thus the macrofossils indicate an Albian Senonian age. The nannofossils consist mainly of Lithastrinus floralis Stradner. Cricolithus multiradiatus Kamptner, C. pemmatoideus Deflandre, Loxolithus armilla (Black) and Parhabdolithus embergeri (Noel). These are typical Albian-Cenomanian species.
