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. Some of the isotopes used for this purpose are uranium, uranium and potassium, each of which has a half-life of more than a million years.

The group also arranged the Arizona testing by not revealing its origins. Austin Long, professor of geosciences at the university, confirmed the tests were performed in his lab but said he was not aware the material was dinosaur bones.  The team has also dated in-situ bone carbonate and/or total organics from seven dinosaurs from Texas to Alaska. Concordant C14 ages were obtained from the different fractions in the low tens of thousands of years, using both Accelerated Mass Spectrometer (AMS) and Beta decay methodologies. (The maximum age range for detecting C14 is 50, to 80, years.) Скрыть.
