Absolute dating methods in archaeology
However, these methods cannot date an object precisely, because the object is dated in comparison with something else; it's not dated in its own right.
However, absolute dating gives a more exact date for an object, because it uses methods like radio carbon or thermoluminescence dating techniques.
Rely on dendrochronology to date petrified trees and forests.
It uses the rings found in trees to set to determine the age of the tree.
Draw on archaeomagnitism when trying to date rocks.
When an archaeological site is excavated the sides of the unexcavated baulk reveals layering of subsequent settlements and activity.
Stratigraphic excavation is the recording and study of these different strata as they are removed from the area.
Consider racemization for once living organisms that are older than 50,000 years old.
This is the cut-off for effective radio-carbon dating.
