Abstract

A method has been developed that uses holographic interferometry to generate contour maps of the occlusional surfaces of fossil teeth. The resulting contour map is, in itself, a valuable descriptive tool. In addition, it provides information for a very large data base, which has been used in trend-surface analysis and Q-mode clustering. As an example, these analytical techniques are applied to a set of Pliocene badger teeth. The same methods can be applied to any paleontological problem dealing with shapes of small objects.
