Can carbon 14 dating be used on stone
The margin of error can be as tight as 30-50 years, though 100 is not unheard of.
We also use stylistic differences to help us get approximate dates. When you get enough of a particular artifact from a particular context, you can get a good median age for that style. Dating organic materials from the layer/vicinity a stone artifact is found is the best way to get a good idea, however, it is far from exact.
Another good dating system is to recognise the caracteristic tools corresponding to a culture.
For example, we know the Solutrean culture existed around 20,000 BP, because we could date some strata on other countless sites.
I studied archaeology, and was specialised in prehistory, so that's largely my domain. Most of the time, stone tools can be dated within their context.
We know pretty much all the characteristic tools for every prehistoric culture in Europe, and when and approximately where they existed.More appropriate methods would be U-Pb on zircon or K-Ar.
