Abstract

In 2002 and 2003, a technological analysis was performed on a collection of 11,000 obsidian objects from the Late Classic and Epiclassic period (circa A.D. 500-900) site of Santa Cruz Atizapan, Toluca Valley, México. This research is part of a broader dissertation project that is attempting to interpret the economic, political and social dynamics that influenced the procurement and use of obsidian in a unique lacustrine environment during a critical period of human occupation in the Toluca Valley. Consistent with most Mesoamerican archaeological assemblages, the obsidian from the Santa Cruz Atizapan site reveals a dominant core-blade technology consisting of modified and unmodified prismatic blade fragments (N=9,399). Prismatic blade scraper, perforator, needle and eccentric forms are represented along with formally and informally shaped non core-blade flake tools (N=220). Projectile points and un-notched bifacially worked tools represent a secondary technology in the obsidian collection (N=337). This report provides a description of the analyzed obsidian and offers preliminary conclusions regarding the role of obsidian within the Santa Cruz Atizapan site during the Late Classic and Epiclassic periods.
