In this study we present a dental microwear analysis of extant Cercopithecoidea primates, based on the analysis of more than dental casts obtained from the osteological collection of the National Museum of Kenya NMK. Journal of Human Evolution Canines represent an essential component of the dentition for any heterodont mammal. We measured tooth wear as the percent dentine exposure PDE, the percent of the occlusal surface on which dentine was exposed , and we examined the relationship of PDE to age, behavior, and life history variables. Dental microwear analysis has proved to be a good indicator of diet and dietary related behaviour in modern humans, fossil hominids and primates. Interproximal tooth wear is caused by tooth-to-tooth rubbing that results in the formation of flat wear surfaces characterized by an intense pattern of enamel pitting caused by prism-plucking. Cataloguing , Bone and tooth , and Hominid. Palaeodemography and dental microwear pattern of Homo habilis in East Africa more. The isotopic signals are indicative of mainly carnivorous dietary regimens for Neandertal populations.
