Figure 14

Scatterplot based on the humerus measurements shown in Table S10. Green represents Batavipusa neerlandica, black Nanophoca vitulinoides, orange Praepusa boeksa, and red Praepusa vindobonensis. The red ellips encompasses both Praepusa species. For the selected characters, the humerus of N. vitulinoides differs noticeably from that of the other considered taxa.
