The study area is geographically bounded by latitude 50 51'N - 50 57'N and longitude 70 51'E – 70 58'E. The area is of the Nkporo shale. Fresh samples of shale were collected from different locations of Amuzu, Amangbara, Anofia Nkanu, Amacha and Ozizza. The samples were analysed and viewed under the microscope, to find out the presences of foraminifera. The fora encountered during the research include: Gavelinella cenomanica, Ramulina Sp, Robertina Sp, Flourensina intermedia, Gavelinella intermedia, Eggerellina mariae, Vaginulina kochii. Most of the fora encountered were calcareous benthic suggesting a shallow marine environment for Afikpo. The fora encountered in the area indicate that it lived at the time where the environment was favourable for its existence. The RobertinaSp, which is abundant in the samples, indicates Campanian – Maastrichtian age for Afikpo and its environs. The fora encountered in the study area are very important for biostratigraphy and can give relative dates to rocks as well as sediments. It was also observed in the study area that foraminifera like Eggerellina mariae and Globigerina belong to the unrestricted genera which inhabit wide range of salinities. This means that it may to large extent tolerate unfavourable environment for its existence. Benthic foraminifera, mostly calcareous benthic make up the highest abundant in the shales of the study area which also suggest that Afikpo and its environs was deposited in the shallow marine environment.

Abstract
The study area is geographically bounded by latitude 50 51'N - 50 57'N and longitude 70 51'E – 70 58'E. The area is of the Nkporo shale. Fresh samples of shale were collected from different locations of Amuzu, Amangbara, Anofia Nkanu, Amacha and Ozizza. The samples were analysed and viewed under the microscope, to find out the presences of foraminifera. The fora encountered during the research include: Gavelinella cenomanica, Ramulina Sp, Robertina Sp, Flourensina intermedia, Gavelinella intermedia, Eggerellina mariae, Vaginulina kochii. Most of the fora encountered were calcareous benthic suggesting a shallow marine environment for Afikpo. The fora encountered in the area indicate that it lived at the time where the environment was favourable for its existence. The RobertinaSp, which is abundant in the samples, indicates Campanian – Maastrichtian age for Afikpo and its environs. The fora encountered in the study area are very important for biostratigraphy and can give relative dates to rocks as well as sediments. It was also observed in the study area that foraminifera like Eggerellina mariae and Globigerina belong to the unrestricted genera which inhabit wide range of salinities. This means that it may to large extent tolerate unfavourable environment for its existence. Benthic foraminifera, mostly calcareous benthic make up the highest abundant in the shales of the study area which also suggest that Afikpo and its environs was deposited in the shallow marine environment.
