Radiometric dating is least useful for dating
Radiometric dating is part of Wiki Project Geology, an attempt at creating a standardized, informative, comprehensive and easy-to-use geology resource.

For example, it may be possible to find arrowheads together with dateable pollen, or tied to wooden arrowstalks, or next to people of a distinct culture whose appearance and disappearance times are known.
If your movie claimed that the arrowheads were radiometrically dated, it's junk.
Unable to find even one such sample, they have given up.
C14 dating has shown not that organic material is older than 50,000 years, but rather that there is not one example of any organic material found on earth that is older than about 45,000 years.
Generally, of artefacts, only wooden artefacts can be dated directly - either by carbon dating or dendrochronology.
For example, volcanic flows of known age (less than a few hundred years old) have repeatedly shown ages far older than they should. Radiometric dating is unacceptable as scientific proof of anything other then our weakness when it comes to radiometric dating.This article is within the scope of Wiki Project Palaeontology, a collaborative effort to improve the coverage of palaeontology-related topics and create a standardized, informative, comprehensive and easy-to-use resource on Wikipedia.If you would like to participate, please visit the project page, where you can join the discussion and see a list of open tasks.This article is within the scope of Wiki Project Physics, a collaborative effort to improve the coverage of Physics on Wikipedia.This article is supported by Wiki Project Elements, which gives a central approach to the chemical elements and their isotopes on Wikipedia.
