FIGURE 1. 1, Landmark configuration on schematic osteoderm of Eutatus; landmarks (dark gray circles) and semi-landmarks (white circles); 2, Box-and-whisker plot showing centroid sizes of E. seguini, E. pascuali and E. crispianii. The central bar of each box represents the median of the population, while upper and lower bounds are 75th and 25th percentiles, respectively. Boxes show 50 % of the population and whiskers extend showing the minimum and maximum values in a range of 1.5 times the length of the box. Circles mark the atypical values of CS located beyond to 1.5 times the box length distances.
