Fig. 4From: Calcaneal proportions in primates and locomotor inferences in Anchomomys and other Palaeogene EuprimatesBoxplots showing the degree of distal calcaneal elongation by taking into account a intrinsic, and b extrinsic proportions on the basis of allometric residuals computed from the primate regression line. Horizontal lines represent the median values, whereas the boxes represent the 25 and 75% percentiles, and the whiskers the maximum–minimum ranges (excluding outliers)Back to article page
