New Species of Dinoflagellate Cysts from the Paleocene of the Anambra Basin, Southeastern Nigeria
Six new species of dinoflagellate cysts and one new combination from the Paleocene to ? lower most Eocene succession in the Alo-1 well, southeast Nigeria, are proposed herein. The new species are Achomosphaera quadrata, Diphyes bifidum, Ifecysta fusiforma, Ifecysta heterospinosa, Palaeocystodinium rafii, and Wilsonidium stellatum. Furthermore, Fibrocysta lappacea (Drugg 1970) Stover & Evitt 1978 is transferred to Ifecysta, and the diagnosis of Ifecysta is emended.
