At Ayalán, the large Integration Period cemetery southwest or Guayaquil, archaeologists excavated a large corpus of metal objects from urn and extended burials (Ubelaker 1981): rings, nose rings, pendants, tweezers, and axe-monies. Axe-monies are thin, axe-shaped pieces of sheet metal (hostler 1986; Hosler, Lechtman, and Hostler 1990), often stacked in packets. They are almost always made of a lower-arsenic copper-arsenic allow. The earliest axe-monies in this region appears at Ayalán. Axe-monies are also common in West Mexico after A.D. 1200 and are discussed in chapters 5 and 6. Radiocarbon determinations show that the earliest date for a burial was associated metal at Ayalán in A.D. 750. The cemetery continued in use until shortly before the Spanish invasion.
