Test excavations at the site of Huistla in Jalisco, Mexico, yielded a series of ceramic types which is similar to types or wares found in the coastal lowland strip of Nayarit and Sinaloa. These affiliations indicate an occupation during a period sometime between about A.D. 800 and 1200. A reappraisal of the Aztatlán complex, recently divided into a series of local phases by Kelley, Winters, and Grosscup, leaves the impression that, while subdivision of the complex is justifed in light of their new data, certain continuities in ceramic design styles between these phases still give substance to the Aztatlán complex.
