Fig. 11. Cross-plot of morphotype membership for each grooved sinistral (A) and dextral (B) specimen on the x-axis and their centroid size along the y-axis. Centroid size is not a measure of length, because the outwards movement of any landmark from the centroid will cause it to increase, but for the sake of providing reference, specimens with a platform length less than 0.4 mm generally had a centroid size below 900.
