Description
FIGURES 9–14. SEM micrographs of Eunotia giraffensis sp. nov. from the Giraffe Pipe fossil locality. 9, 11. Close-ups of the end of a valve face showing the straight distal raphe end and the closer-spaced striae at the valve apex. 10, 12. Internal views of the helictoglossa and distal raphe end. Note the extended hyaline region surrounding the helictoglossa, thickened margin of the valve around the apex, densely-spaced striae on the mantle below the raphe, and the presence of a rimoportula. 13, 14. Girdle views of the ventral mantle depicting the position of the raphe, hyaline region surrounding the raphe, and the densely-spaced striae on the mantle below the raphe. Scale bars = 2 µm (Figs 9–12, 14), 3 µm (Fig. 13).
