FIGURE 33. The distribution of proximal interstriae distances along the semivalve transect in Pinnunavis edkuensis, P. yarrensis, P. zalatii ("aegyptiaca" subset only) and the Port Elizabeth samples. Regression lines are solid; 98% confidence intervals for the regression lines are indicated by dashed lines. A traditional striae density scale is provided along the right side of the plot.
