FIGURE 3. Principal component analysis of the lower dentition showing plots of components 1 against 2 and the table of results of the PCA from PC1 and PC2. Measurements: L and W (max.) of m1 and m2 and L of m1-m3. ∆ - S. subaraneus (Germany), ▲ - S. subaraneus (Poland), ○ - S. araneus (fossil), ● - S. araneus (recent), x - S. runtonensis.
FIGURE 4. Box Plot with the mediana the maximum - minimum values and 25-75% quartiles from PC1 of the lower dentition. S.s (G) - S. subaraneus (Germany); S.s (P) - S. subaraneus (Poland); S.a (R) - S. araneus (recent); S.a (f) - S. araneus (fossil); S. r (P) - S. runtonensis. The same letters indicate no significant differences between the groups compared.
