Artifacts recovered during U.C.L.A. excavations in 1959 are described in terms of a new typological classification for Mesoamerican metal artifacts. In addition to a number of artifact types known elsewhere in Mesoamerica, the excavations yielded several new forms. Possible relationships of Amapa, and West Mexico in general, to other areas of Mesoamerica, suggested by similarities in metal artifacts, are discussed. Association of metals with Mazapan figurines suggests an initial date for appearance of metal artifacts at Amapa of roughly A.D. 900; terminal date for the Amapa occupation may be around 1200.
