May contain a first or last xeroxed page. Abstract: "A 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.".
