Figs 7–10. Ventimolina stellata SEM images of two cells from the NW Mediterranean. 7 – complete coccosphere; 8 – detail of BC from the cell shown in Fig. 7. The arrow points to a coccolith calyx that is clearly convex; 9 – complete coccosphere. The arrow points to a CFC that clearly shows the central are calcification and further lends support to the interpretation of the calyx being perpendicular to the longest axis of the CFC; 10 – detail of BC from the cell shown in Fig. 9. A distinctly convex coccolith calyx is pointed out by arrow.
