Figure 3

Scatterplots showing variation on PC1 - PC4. These axes represent 39.76%, 20.36%, 14.92% and 6.14% of variance. Based on species means. Fossil pinnipeds are as follows: En, Enaliarctos emlongi; Al, Allodesmus sp.; Po, Pontolis magnus; Pi, Piscophoca pacifica; Ac, Acrophoca longirostris. Polygons connect fissipeds (red) and extant pinnipeds (blue) and reflect groupings used in the disparity analyses. Extremal shapes are shown in FigureĀ 4.
