Only hard parts, like bones and teeth, can become fossils.But for some people, the discovery raised a different question.

In fact, due to the difficulties in applying the experimental method to events in the past, all chronometers based on natural or artificial nuclear disintegration need a calibration.Isotopes of a particular element have the same number of protons in their nucleus, but different numbers of neutrons.This means that although they are very similar chemically, they have different masses.Radiometric dating relies on the properties of isotopes.These are chemical elements, like carbon or uranium, that are identical except for one key feature -- the number of neutrons in their nucleus.How do scientists know the bones are really 68 million years old?

Today's knowledge of fossil ages comes primarily from radiometric dating, also known as radioactive dating.

The discussion of some phenomena taking place during rock crystallization reveals huge discrepancies between the model theory and the reality.

Anomalous « K/Ar model ages » are frequently reported in the literature.

If those rocks really have been sitting around on the moon for billions of years, I suspect that the the wide range of physical and chemical processes which occurred over that time period had a much more profound effect on the uncertainty of the age determination.

This is best illustrated by the radioactive age of a sample of diamonds from Zaire.

These assumptions are not demonstrated, only supposed to be true.
