Abstract

A total of nine genera of ostracods from the Yola Arm in the north-east of Nigeria are described. The various species, though from outcrop sections, supplement the list from the Upper Benue Trough already reported from Ashaka quarry and borehole (BH 2340) of the Gongila and Pindiga Formations respectively. The species described belong to six families namely; Brachicytheridae, Bythocytheridae, Cyprididae, Trachyleberididae, Cytherideidae and Cytherellidae. Some of the species are evidence of faunal dispersion during the Mid-Cretaceous marine transgression of the North and West African basins.
