1	Lithic Production at the Mesilla Phase Placitas Arroyo Site Complex Doña Ana County, New Mexico Younger, Alexandra Carla 08 1900 (has links) This study of lithic analysis shifts attention from typological studies to explicitly behavioral analyses, complimenting studies of both intrasite and intersite patterns of variability and change. Analysis of several assemblages from the Placitas Arroyo site complex reveals changing patterns of raw material procurement and selection, core reduction strategies, as well as tool production and discard. The most striking result thus far is the quite uniform emphasis on flake production from well-prepared cores, and the near absence of manufacture or maintenance of bifacial tools, especially projectile points. Associated with common ground stone artifacts, the flaked stone materials may well represent intensive food processing. Regardless, the technological patterns being revealed by this approach illustrate a productive new means to gain insights into changing behaviors in the Jornada Mogollon cultural tradition. lithic production reduction lithic analysis flake core technology southern new mexico jornada mogollon southwest formative mesilla prehistoric placitas arroyo northern chihuahua desert
