FIGURE 21. Discriminant analysis of Pinnunavis edkuensis, P. zalatii, P. yarrensis and the Port Elizabeth samples using relative warp scores describing mantle shape. The "aegyptiaca" and "elliptica" subsets of P. zalatii were treated as separate groups. Two very close centroids are labeled: P. edkuensis as "edku" and the "aegyptiaca" subset of P. zalatii as "aegypt". The black lines define a Voronoi tesselation of the two-dimensional shape space. The percentage of the total variation in mantle shape variation explained by each discriminant function is indicted in the chart axis titles.
