Techniques for carbon dating of organic paint binders, costly and often problematic, include accelerator mass spectrometry (AMS), spectroscopy, amino-acid analysis, scattered electron microscopy (SEM) and chromatography.
(1996), who dealt with hundreds of lumps and actual drops of red ochre, and Haynes et al.
(1952) who dated an Amazonian Paleoindian Site, stating in their Technical Comments that dating was based on abundant paint spatters of the same chemical composition as the art. (198) also found hundreds of lumps of red ochre, as well as two small pigmented wall spalls in Caverna da Pedra Pintada. (19-67) found engraved stones in sealed radiocarbon-dated, 10,000 year-old archaeological levels at Wonderwerk Cave in the northern Cape Province of South Africa.
(6)   Macintosh (1965), Wakankar (1983), Combier (1984), Linares (1988) and Chippindale and Tacon (1998) indirectly dated wall art by They were unconvincing because pigments are amorphous and change colour with exposure, blending, distance to camera, wetness, lighting, binders (and their decomposition) and source.
Pigments fallen to the soil may be protected from sunlight, but soil p H, water and other minerals can alter their colour.
Other papers include Mazel and Watchman (1997) on Natal Drackensberg paintings, Prous (1999) on Brazilian rock art, Watchman and Cole (1993) on plant fiber binders in northern Australian rock paintings and Chaffee, Loendorf, Hyman and Rowe (1994) on a Pryor Mountain pictograph in Montana.
CR (cation ratio) dating (Loendorf 1990) does not work. They AMS-dated rock art penetrating the soil surface to a level yielding an uncalibrated age of 1920140 years.Style and age may have no relationship, and elegance of design may deteriorate as new art is introduced.Lichen growth begins any time after the art, while ethnohistoric records of the art seldom exceed several centuries.We are constantly amazed how beautiful and puzzling ancient art can be, so it is fascinating to know when it was made.Dating helps to ease our fascination, but it also helps us track the spread of a culture or art form across the land.(5)   Fallen petroglyph or pictograph fragment dating was done by Susino (1999) in Australias Mutawintji National Park and near Sydney on cultural microdebitage (quartz grains), establishing their rock engraving periods.
