• Dental microwear analysis has proved to be a good indicator of dietary related abrasion in humans, fossil Hominids and Primates. Diets based on hard vegetables, such as leaves, medulla or fibers, produce a greater number of microstriations on the buccal enamel surfaces of molar teeth, as well as longer striations. In this study we present a dental microwear analysis of several extant primate species belonging to Hominoidea and Cercopithecoidea, using more than 1200 dental casts obtained from different osteological collections. The sample selected consists of 150 replicas carefully chosen from the large sample available. Specific, sub-specific, geographical, sexual and ecological differences have been observed in the microstriation pattern within the sample studied. The analysis of the inter- and intragroup variability of these Primate species will allow to interpret fossil primate and Hominid diets.
