Arizona Radiocarbon Dating Lab Turns 25

A ROW that threatens the reputation of a leading expert in dating prehistoric artwork has thrown studies on rock art into confusion. Beck and Jull say that the samples seem to contain ground coal and charcoal of widely differing ages. This is a natural coating of iron oxides and manganese, deposited by microorganisms living on the rock surface. When the rock varnish is damp, wind-blown debris, including carbon-bearing plants, pollen or insects, can stick to it. Archaeologists date such artwork by sampling the trapped organic material that lies closest to the carving.
