| Abstract: | Mastication of dietary items with different mechanical properties leaves distinctive microscopic marks on the surface of tooth enamel. The inspection of such marks (dental micro wear analysis) is informative about the dietary habitués in fossil as well as in modern species. Dental micro wear analysis relies on the morphology, abundance, direction, and distribution of these microscopic marks. We present a new freely available software implementation, Micro Wear, that, compared to traditional dental micro wear tools, allows more rapid, observer error free, and inexpensive quantification and classification of all the microscopic marks (also including for the first time different subtypes of scars). Classification parameters and graphical rendering of the output are fully settable by the user. Micro Wear includes functions to: (a) sample the marks, (b) classify features into categories as pits or scratches and then into their respective subcategories (large pits, coarse scratches, etc.), (c) generate an output table with summary information, and (d) obtain a visual surface-map where marks are highlighted. We provide a tutorial to reproduce the steps required to perform micro wear analysis and to test tool functionalities. Then, we present two case studies to illustrate how Micro Wear works. The first regards a Miocene great ape obtained from through environmental scanning electron microscope and other a Pleistocene cervid acquired by a stereomicroscope. |
