The first series of radiocarbon dates to be obtained from a deep shaft-and-chamber tomb of the type restricted in Mesoamerica to parts of Nayarit, Jalisco, and Colima in western Mexico ranges from 2230 ± 100 years to 1710 ± 80 years. Examination of the evidence indicates that for the present a date equivalent to A.D. 250 should be accepted for at least one phase, possibly a late phase, of the shaft tomb culture and for the hollow, polychrome figurines associated with the tombs.
