Other techniques include analyzing amino acids and measuring changes in an object's magnetic field.

Scientists have also made improvements to the standard radiometric measurements.

The extreme temperatures of the magma would just destroy the bones.

To determine the ages of these specimens, scientists need an isotope with a very long half-life.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]. There are two main methods determining a fossils age, relative dating and absolute dating.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.
