Description :
The conclusion of the A. is that the interpretation of radiocarbon ages associated with rock varnish is unclear, and there may be similar problems associated with other rock coatings. To obtain reliable ages in the future, the effort must be based on a careful characterization of different types of organic matter associated with rock varnish. In addition, the ages of different types of organics must be measured where there are independent age controls, and in blind tests.
