Fig. 8. Dorsal and ventral views of right foot and hand segments respectively showing measurements taken: A = calcaneal length, B = calcaneal outlever length, C = cuboid length, D = fourth metatarsal length, E = fourth proximal pedal phalanx length, F = fourth middle pedal phalanx length, G = third metacarpal length, H = third proximal phalanx length, I = third middle phalanx length. Calcaneal outlever length (B) was calculated from linear measures of the calcaneus as reported in Sarmiento (1994). A+C+D+E+F and B+C+D+E+F were taken as approximations of foot length and foot outlever
