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.
When creation scientists studied granite samples, they made interesting discoveries.
Zircon should not be confused with cubic zirconia, which is a man-made material.
Zircon is present in most soils and clastic sediments.
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.

When paleontologist Mary Schweitzer found soft tissue in a Tyrannosaurus rex fossil, her discovery raised an obvious question -- how the tissue could have survived so long?
The bone was 68 million years old, and conventional wisdom about fossilization is that all soft tissue, from blood to brains, decomposes.
Dating and Chronology of Prehistoric Art A number of highly sophisticated techniques - such as radiometric testing, Uranium/Thorium dating and thermoluminescence - are now available to help establish the date of ancient artifacts from the Paleolithic era and later.
However, dating of ancient art is not an exact science, and results are often dependent on tests performed on the 'layer' of earth and debris in which the artifact was lying, or - in the case of rock engraving - an analysis of the content and style of the markings.
The early sculptures known as the Venuses of Tan-Tan and Berekhat Ram, are such crude representations of humanoid shapes that some experts doubt whether they are works of art at all.
