Sexual dimorphism of the weight of the skull in African cercopithecidae (primates, catarrhini).
As we had to determine the sex of Cercopithecidae with the help of their skulls, we employed the usual method of measuring the length of their canines. Since we had to consider some doubtful cases, we wondered if we could confirm the diagnosis on the basis of another practical variable. Skull weight seemed to be one such possibility. We weighed 447 skulls from different genera and species of African Cercopithecidae. Whereas the t test confirmed the existence of a sexual dimorphism at this level, discriminant analysis gave a discriminating value to the weights of skulls.
