Mesowear

DSC_0090.JPGMesowear analysis was developed by Fortelious and Solounias in 2000 and measures attrition and abrasion on selenodont ungulate upper molars. Mesowear analysis measures the abrasion of upper molars on selenodont ungulates and has been shown to be a reliable proxy for diet in both extant and extinct species, specifically in distinguishing the degree of browse vs. graze in the diet. Mesowear is a function of dental wear over ca. the last 6 months of an individual’s lifetime and is independent of the effects of seasonality, migration patterns or stochastic effects, such as the effects of the individual’s last meal, which is common in other paleodietary methods. Mesowear measures two variables, occlusal relief and occlusal shape, on the paracone of upper M1/M2 of selenodont ungulates. Occlusal relief has two variables: high and low, which are dependent on the height of the cusps above the valley between them. Occlusal shape has three variables: sharp, round and blunt.

In our lab we are working on using cervid and bovid mesowear as a paleoecological proxy in Mediterranean environments
