Figure 10. Morphotypes A and B of morphocline B from an Early Pleistocene (1.8-1.6 Ma) time-slice showing latitudinal trends in mean coccolith diameter and mean number of elements. The data included represent only coccoliths from morphocline B of Knappertsbusch et al. (1997), see Figure 11 for further explanations. The samples, that are included in this figure (labelled with ID numbers in brackets) are listed in Table 1. The vertical bars represent ±95 % univariate confidence intervals from the means. Explanation of symbols: Solid (black) = mean coccolith diameter in µm. Open (red) = mean number of elements in the distal shield.
