But this sediment doesn't typically include the necessary isotopes in measurable amounts.

Fossils can't form in the igneous rock that usually does contain the isotopes.

Dinosaur bones, on the other hand, are millions of years old -- some fossils are billions of years old.

To determine the ages of these specimens, scientists need an isotope with a very long half-life.

In the process the paper refutes a number of misconceptions prevalent among Christians today.

This paper is available on the web via the American Scientific Affiliation and related sites to promote greater understanding and wisdom on this issue, particularly within the Christian community.

Radiometric dating--the process of determining the age of rocks from the decay of their radioactive elements--has been in widespread use for over half a century.

For example, by using a laser, researchers can measure parent and daughter atoms in extremely small amounts of matter, making it possible to determine the age of very small samples [source: New Scientist].

Wiens has a Ph D in Physics, with a minor in Geology.

Using the basic ideas of bracketing and radiometric dating, researchers have determined the age of rock layers all over the world.

This information has also helped determine the age of the Earth itself.Other techniques include analyzing amino acids and measuring changes in an object's magnetic field.
