After this point, other Absolute Dating methods may be used.Amino acid dating: Physical structure of living beings depends on the protein content in their bodies.The changes in this content help determine the relative age of these fossils.Thermoluminescence: It determines the period during which certain object was last subjected to heat.It is based on the concept that heated objects absorb light, and emit electrons.
