Fig. 6 in A practical, step-by-step, guide to taxonomic comparisons using Procrustes geometric morphometrics and user-friendly software (part B): group comparisons

Fig. 6. PC1–PC2 of mean shapes for the random, mutually exclusive, species subsamples. Shape variation (magnified five times) at the opposite extremes of each PC is shown using wireframes, as well as deformation grids and expansion factors computed in PAST using the thin plate spline interpolation. (In these wireframes, unlike those in MorphoJ, the mental foramen is also connected by a line to its neighbouring landmarks, as PAST constrains users to link all landmarks: the difference is, however, minimal and purely visual).
