Fig. 2

Principal component plots (left column: PC1 v/s 2, right column: PC1 v/s PC3) of the upper face (top), midface (middle) and mandible (bottom) utilizing residuals from a multivariate linear regression of facial shape on log centroid size. Specimens from JP and NAP collections are colored in blue and red, respectively. Plots depict distribution of specimen along PC1 (x – axis) and PC2 or PC3 (y-axis) with 80% confidence ellipses for each population. The first three components explained 40.28%, 31.82%, and 17.93% of shape variance in the upper face; 38.38%, 20.10%, and 12.10% in the midface; and 29.23%, 15.01%, and 10.19% in the mandible.
