Gibberleberis elongata Dingle, 1980 Figs 52D, 53A Gibberleberis elongata Dingle 1980: 57-59, figs 30E-F, 31A. Remarks A rare species first recorded from the Richards Bay BH-9 borehole and since located at one horizon (at locality 110, Nibela Peninsula) at outcrop. Age, distribution, palaeoecology Santonian III to Campanian II (Richards Bay BH-9 borehole, Nibela Peninsula, Zululand). G. elongata occurs in trace numbers in ostracod assem- blages 2, 2-3 transition, 5a and 4b (Fig. 50F). It is not possible to determine a preference because of the small numbers of specimens found at each horizon, although the species seems to be restricted to water shallower than 300 G. elongata.
