Foraminifera and Paleoenvironments of the Tertiary Ogwashi Asaba Formation, Southern Anambra Basin, Nigeria

Abstract

Foraminifera assemblages and paleoenvironmental investigation were carried out on the outcropping rocks of the Tertiary Ogwashi Asaba formation, Southern Anambra Basin. Several researches have indicated the usefulness of foraminifera in the construction of paleoenvironment and its significance in paleoecological studies (Luciani et al., 2016; Wolfgring and Wagreich, 2016; Nouradini et al., 2015; Milker et al., 2015; Thibault de Chanvalon et al., 2015). These foraminiferals are group of organisms that are ubiquitous throughout the world’s oceans, but the distribution of individual species especially the benthics is constrained by their environmental preferences.
