Abstract: The present study focuses on the modern taxonomical consideration of thirty-six smaller benthic foraminiferal Paleogene species belonging to twenty-six genera identified by Bignot (1988) from Holes 960a and 960c of the Ivorian Basin, West Africa, central Atlantic Ocean, representing a good example of the Tethyan assemblage; the Southern Tethyan assemblage of the Ivorian Basin indicates an open marine environment, corresponding to an outer neritic-abyssal setting, with its wide paleogeographic distribution across various localities in the Northern and Southern Tethys—USA, Mexico, Caribbean, Peru, Venezuela, Brazil, Spain, France, Germany, Sweden, Austria, Hungary, Italy, Ivorian Basin, Angola, Libya, Egypt, United Arab Emirates (UAE), Pakistan, and New Zealand—demonstrating that the ancestral Tethys was connected to the ancestral Atlantic, Indian (via the Mediterranean Sea), and Pacific Oceans, while the environmental conditions of the identified species indicate an outer shelf-bathyal habitat (~200–2000m).
