Figure 8

Shape deformations according to the second PLS whole dimension. The sequence of surface representations (from left to right) as deformations of the average shape correspond to increasing scores of the second PLS whole dimension in Figure 6. The surface morphs differ from its neighbors by equal multiples of the standard deviation of the actual variability. The first and last column is extrapolated by 4 standard deviations. Major covariation between blocks lies in the angle between bill and cranium and in the position of the foramen magnum. (b): Exemplary representation of the positional change of the foramen magnum. The dashed line represents the dorsal margin of the foramen magnum of the consensus.
