Fig. 8. Cross-plot of the first two principal components (labeled with their corresponding eigenvalues) and wireframes (A) and canonical variation plot (using chirality membership as the group defining criterion) and wireframes (B) for Idiognathodus luganicus. Black wireframes, form with values of the corresponding principal component values; gray wireframes, mean form provided by the preliminary Procrustes fit; blue/red wireframes, form achieved with values of the corresponding canonical variate; blue, sinistral; red, dextral.
