There is something too jazzy about dating an old man.

    Significance half life radiometric dating techniques

    Using relative dating the fossil is compared to something for which an age is already known.

    The half-life is the amount of time it takes for one half of the initial amount of the parent, radioactive isotope, to decay to the daughter isotope.

    Absolute dating is used to determine a precise age of a fossil by using radiometric dating to measure the decay of isotopes, either within the fossil or more often the rocks associated with it.

    The majority of the time fossils are dated using relative dating techniques.

    Carbon dating is used to determine the age of biological artifacts up to 50,000 years old.

    This technique is widely used on recent artifacts, but educators and students alike should note that this technique will not work on older fossils (like those of the dinosaurs alleged to be millions of years old).
