Fig. 8. Estimating the number of missing specimens from Madene El Mrakib. A. Diameter plotted in log; the dashed line demarcates the possibly missing data based on the highest count at a diameter of 4 mm. B. Diameter plotted linearly; prepared specimens are marked by the blue field; the black dots mark the sums of prepared and crushed specimens; the orange field adds those specimens, which we might have missed entirely, either because of non-preservation or because they were overlooked during preparation; this is based on the regression line that was moved to the highest point of small specimens.
