Very few artifacts recovered from an archeological site can be absolutely dated. Archeologists use several methods to establish absolute chronology including radiocarbon dating, obsidian hydration, thermoluminescence, dendrochronology, historical records, mean ceramic dating, and pipe stem dating.Very few artifacts recovered from an archeological site can be absolutely dated.

What methods do scientists use to date things?
While radiocarbon dating is useful only for materials that were once alive, scientists can use uranium-thorium-lead dating to measure the age of objects such as rocks. In this method, scientists measure the quantity of a variety of different radioactive isotopes, all of which decay into stable forms of lead.
All archaeological materials can be grouped into four main categories: (1) artifacts, (2) ecofacts, (3) structures, and (4) features associated with human activity. Artifacts and ecofacts are portable and thus can be removed from the site to be analyzed by specialists.
