FIGURE 27. Discriminant analysis of Pinnunavis edkuensis, P. zalatii, P. yarrensis and the Port Elizabeth samples using relative warp scores describing axial area shape. Subsets of all taxa were treated as independent groups, except for P. edkuensis, as there were no subgroups. The centroids (+) of the "aegyptiaca" and "elliptica" subsets of P. zalatii are labeled. 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.
