A study of the conarticular surfaces in the reconstructed wrist of Dryopithecus (Proconsul) africanus reveals that they most probably attained their close packed and habitual position when the hand is dorsiflexed as occurring in the palmigrade quadrupedal stance and locomotion of Alouatta and Ateles. This report denies knuckle walking as a possible locomotive habitus for D. (Proconsul) africanus, and proposes Alouatta and Ateles as the best available models for the locomotor behavior of D. (Proconsul) africanus.
