Fig. 4. Correlations between body size (using femoral length as a proxy) and discrete characters. A. Anterolateral process on proximal ulna. B. Manual unguals. C. Femur longer than tibia. D. Fourth trochanter morphology. For A–C, 0, feature absent; 1, feature present; for D, 0, fourth trochanter pendant; 1 , fourth trochanter reduced to crest; 2, fourth trochanter reduced to rugose ridge or absent.
