Abstract
The purpose of this study was to develop and analyze methods for determination of age and sex for the Japanese wild boar (Sus scrofa leucomystax). The following results were obtained: (1) Eighty-nine skulls of wild boar were divided into five age groups on the basis of tooth eruption and wear, (2) the annual layers in dentin and cement of the first lower molar permitted the recognition of five age groups separated by one year (7-8, 19-20, 31-32, 43-44, 55- month), (3) an annual layer consisted of two bands, one broad and one narrow, and it was shown that the latter was hypercalcified, (4) no significant difference could be demonstrated between the tooth eruption of known age captives and that of wild boars, and (5) of three sex criteria examined in this study, canine root was the best character for sex determination, especially for younger animals.
