✦ Synopsis

Certain cultural information is expreseed in the morphology of projectile points. The present paper presents a technique that can extract a large amount of information in the shape of these points. Using a mncept from fractal geometry, the degree of shape irregularity is quantified. This technique can be used to document variability in shape of individual pints within a point type. or among point types. In this paper, the shapes are segmented into two components (structural and textural), and points of similar chara&risties plot closely in bivariate plots of these components. If necessary, the method can be modified to provide information at more than two scales.
