Lithic Production and Consumption Patterns from the Great Platform at Late Postclassic (A.D. 1350–1525) Tzintzuntzan, Mexico

Abstract

ABSTRACTLate Postclassic period (a.d. 1350–1525) Tarascan economic activities often included higher degrees of political involvement and territorial control compared with other ancient Mesoamerican societies. Here I examine Tarascan obsidian economies through an analysis of lithic production and consumption patterns from structures excavated on and near the Great Platform at the imperial capital of Tzintzuntzan. Four spatially distinct patterns are evident. Great Platform residents used high-quality obsidian blades as ceremonial items or burial offerings and scrapers for craft production. Lower elite residents of Structure F, outside the Great Platform, produced their own blade tools and consumed a higher percentage of green obsidian than residents of the Great Platform. Excavations at Yacata 3 recovered bifacial arrowheads and obsidian bloodletters associated with disturbed offerings. The spatial distributions of lapidary preforms and highly polished fragments combined with accounts from the Relación de Michoacán (a.d. 1541) suggest that lower elites produced obsidian jewelry near the Great Platform.
