A longitudinal study of the palatal growth of 80 male and 81 female Macaca nemestrina reveals that male growth rates are greater than female growth rates. In addition, both sexes demonstrate a similar pattern of palatal growth although growth rate differences between sexes probably reflect the larger canine/P3 apparatus and overall body size of males. Growth of the premaxillary and postmaxillary palatal segments appear to be independent of one another. Palatal growth spurts, obvious in males, exist for two palatal length dimensions. The maxillary tuberosity growth center is postulated to account for more size dimorphism between sexes than the premaxilla growth center.
