Rocks or Dirt. Most of the time geologist will use these to determine factors from the surrounding area such as how old it is, as well as how long its been there.
Relative dating is a method which was used earlier. In this technique an objects relation to the layer of deposits in the area was used to estimate the age of artifact. This is still heavily used, but now more accurate dating techniques are used. Radiocarbon dating is one of them. In radiocarbon dating the age of an artifact is determined by measuring the carbon-14 content in the fossil. When an organism dies the amount of carbon-14 starts to decay as the organism decays. the amount of Carbon-14 left in the artifact can tell us about its age.
