Abstract

In recent years, lithic studies have emphasized the role of technology in the overall adaptation of past societies to their environments, including the economization of lithic resources. This paper explores how particular characteristics of individual, unretouched flakes can be altered in ways that increase their economy, as reflected in the ratio of edge length to mass. Results of controlled laboratory experiments are presented that identify exterior platform angle and platform depth as being primary independent variables affecting this ratio. These relationships are then tested against a number of archaeological assemblages.

Resumen

Resumen

En los últimos años, estudios Uticos han enfatizado el papel de la tecnologίa en la adaptación total de sociedades del pasado a sus ambientes, incluyendo la economización del recurso lίtico. Este articulo explora la forma en que las caracterίsticas particulares de lascas individuas no retocadas pueden ser alteradas enformas que aumentan su economίa, como se refleja en la relación entre la longitud del filo y la masa de la lasca. Se presentan resultados de experimentos controlados de laboratorio que identifican el ángulo exterior de la plataforma y la profundidad de la plataforma como variables independientes principales que afectan esta relación. Estas relaciones se prueban con una serie de conjuntos arqueológicos.
