The Geography of Teeth

A University of Arkansas professor is using laser mapping and GIS to explore the terrain of fossilized teeth. It turns out that the pits and bumps on teeth are a good indicator of what prehistoric animals ate. Called dental topographic analysis, the process involves a laser which reads the three-dimensional coordinates of the tooth at one-thousandth-inch slices along the surface. The software then calculates coordinates and produces a three-dimensional map of the tooth.
