Fig. 3. Interpretational drawings of coccolith structure within species of Papposphaera. Intraspecific variation is shown where relevant. A – P. sagittifera; B – P. sagittifera cfr.; C – P. sarion; D – P. arctica; E – P. iugifera; F – P. heldalii; a – body coccolith central area calcification; b – calyx design; c – calicate coccolith central area calcification; d – holococcolith contour (flagellar pole coccolith); e – holococcolith contour (body coccolith). Notice the inclusion of schematic drawings of a rosette wing from each of the P. sagittifera types of calyces.
