However if the knife has a handle made of natural organic material (e.g, wood, bone, antler, ivory) this handle can be carbon-14 dated to obtain an estimate of the age of the knife.Among many methods, carbon dating is most commonly used to date fossils.It isn't 0 Carbon dating uses the radioactive isotope Carbon-14 which has a half life of 5730 years.It may be used to date organic materials up to roughly 40,000 years old.Rocks are dated using other methods, such as Uranium-Lead dating, which has a much longer half life (over 700 million years).Carbon 14 is used, mainly by archaeologists, to date bones and other formerly living matter but not normally fossils.

Stratigraphic dating (dating based on ages of layers above & below fossil). To date fossils, or rather the rocks in or near where the fossils are found, we use radioactive isotopes which have a much greater half life.

From 2001 through 2005, Case will remove one dot for each year.

From 2006 through 2009, Case will remove one "X" each year.

This is because the half-life of that isotope is 5730 years; it is useful for dating up to 50,000 - 60,000 years but no more.

There are many other isotopes of various elements used for dating the strata in which fossils are found.
