| Summary: | Fig. 8. Schematic drawings of coccolith structures in species of Papposphaera (not drawn to scale). a – body coccoliths; b – calyx design; c – coccoliths with central processes; A – P. sagittifera; B – P. sarion; C – P. arctica; D – P. iugifera; E – P. heldalii. Notice that alternative shapes are included for some species (A/a, B/a, D/a) and that the P. sarion design for a coccolith with a central process (B/c) is potentially as variable as B/a.
