Carbon dating at the University of Georgia Center for Applied Isotope Studies placed organic inclusions in the Atzlan artifacts at approximately 8,600 years old. The plant resin adhesive with aluminum, calcium, and silicon also dates to roughly the same period—significantly predating any known civilization in Jalisco, Mexico.
