Details
In an investigation into sex differences in the crania of a species of Macaca fascicularis (a type of monkey), random samples of 9 male and 9 female skulls were obtained by Paul O’Higgins (Hull-York Medical School) (Dryden and Mardia 1993). A subset of seven anatomical landmarks was located on each cranium and the three-dimensional (3D) coordinates of each point were recorded.
