Specialized Ground Stone Production in the Casas Grandes Region of Northern Chihuahua, Mexico
Previous research has identified specialized production of prestige goods during the Medio period (A.D. 1200-1450) in the Casas Grandes region of northwestern Mexico and the American Southwest. We evaluate the organization of production of two functionally equivalent types of trough metates from Paquimé, Chihuahua, Mexico, using the standardization hypothesis, i.e., the premise that products produced by specialists have less variation than those manufactured by less-specialized producers. We find that the morphology of one of the metate types (Type 1A metates) is statistically more standardized than the other (Type 1B metates). We then compare the Paquimé metates to those manufactured by generalized producers from the Mimbres Valley region of New Mexico. We find that Mimbres through-trough metates and the Type 1B metates from Paquimé have a similar degree of morphological variation, but that the Type 1A Paquimé metates are morphologically more standardized, indicating that specialists produced them. We conclude that specialized production in the Casas Grandes region was not limited to prestige goods but was instead a fundamental organizing principle of the Medio period economic system, reflecting the presence of a well-established social hierarchy and exchange system.
