An exhaustive analysis of political and economic change right through the sequence of Maya civilization, based on the direct evidence of chipped stone assemblages from a wide variety of contexts in two regions. The acquisition of raw materials, the production of tools, and the use of tools are all fully considered for what they can tell us about long-distance political and economic relations and local economic organization. An unexpected bonus of the study was information on the use of chipped stone in warfare. The full dataset is provided electronically. Complete text in English and Spanish.
