<p>The Symmetry Index (SI) and the Primary Aperture Diameter Ratio (PADR) are defined in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0128108#pone.0128108.g001" target="_blank">Fig 1</a>. Dashed line indicates the best discrimination between specimens attributed to the <i>trilobus</i> (blue) and <i>ruber</i> (red) lineages, determined by linear discriminant analysis between the two groups in Zone M3. The line is perpendicular to the linear discriminant function at the position of the optimum discrimination score (z = 0). Specimens on each side of the line would be classified as belonging to either one of the groups in Zone M3.</p>
