Figs 17–22. Papposphaera sagittifera combination coccospheres (TEM whole mounts from West Greenland). 17 – separated halves of a combination coccosphere; 18 – detail of calyces from Fig. 17 showing the regular triangular outline; the arrow points to a rosette wing that has a distal stepwise notching; 19 – combination coccosphere with the two halves united; 20–21 – detail of the calyces from Fig. 19; the arrow (Fig. 20) points to a rosette wing with a distal step-wise notching; 22 – the four rosette wings are spread out in a fan-like manner clearly showing the shape of the individual wing: the arrow points to a rosette wing with a distal step-wise notching.
