Kruskal-Wallace and pair-wise Mann-Whitney U non-parametric tests for significant differences in maximum shape change (PRIN 1) among the postures of the sampled taxa based on the median score of PRIN 1.

Significant differences among the taxa sampled (p*Saurischia was divided into Sauropoda (parasagittal obligate quadrupeds) and parasagittal bipeds (Theropoda (Aves inclusive)+Basal Sauropodomorpha).**Eutheria was treated as one postural category: parasagittal obligate quadrupeds.
