A Functional Analysis of “Clear Fork” Artifacts From the Rio Grande Plain, Texas

Abstract

AbstractA series of "Clear Fork" tools from the Rio Grande Plain of southern Texas have been subjected to a functional analysis. Macroscopic, microscopic, and edge angle studies were conducted. A high frequency of nibbling wear was recorded on steeply-angled working edges. Comparisons of these data with several published studies indicate that this tool form was used in the working of wood or other tough materials.
