摘要
Although Colobine monkeys are one of the most common prey hunted by Southeast Asian prehistoric humans, no data concerning tooth eruption and wear are available for these species. Dental wear eruption and attrition are used for attributing ages to individual fossils in order to construct mortality curves, and are also useful in reconstructing fossil life histories. Such wear sequences partly exist for Cercopithecines. Although Cercopithecines and Colobines are both bilophodont, they present significant differences in terms of diet, detailed tooth morphologies and occlusion. This paper aims to formulate a guide for the dental eruption and attrition of extant Trachypithecus specimens, the most folivorous of all the Colobines. We also propose to calibrate the eruption and wear stages that we define here with absolute ages available in the literature.
