The relationship between cranial and humeral shape with soil type. For all cranial and humeral PCs, positive scores correspond with shapes derived for digging in harder soils; convex hulls are colored according to taxonomy (Fig. 1) ai. Points are colored according to soft, medium, and hard for each soil condition: percent clay a, d, g, bulk density b, e, h and linear extensibility c, f, i with bin categories after Marcy et al. 2013 [27]
