Special care was taken to prevent this kind of contamination. 10 Living animals take in carbon-14 on a regular basis.
Radioactive isotope dating fossils
But, if they were not that old, merely thousands of years old, then carbon-14 dating applied to dinosaur fossils might detect some carbon-14 atoms. These findings about dinosaur fossils are just a piece of the evidence indicating assumed ages are perhaps mistaken.
Other pieces include carbon-14 in diamonds, other soft tissue found in dinosaur fossils, and evidence that conventional dating methods are inaccurate.
The age for all these fossils was found to be less than 50,000 years1.
This is not predicted by conventional evolutionary theory; and other discoveries have been made concerning dinosaurs which also are not predicted by evolutionary theory such as the discovery of soft tissue in bones that are not or are only partially fossilized.
Scientists have done studies which suggest that dinosaurs lived millions of years ago, but those dates were not arrived at by use of carbon-14 dating methods.
There are other dating methods, making use of materials with even longer half-lives, such as the potassium=argon method, which have been used in dating dinosaurs.Dinosaurs supposedly died out 65 million years ago. Carbon-14 dating was recently performed on dinosaur fossils,1 and the results were presented at the Western Geophysics Meeting in Singapore, August 2012, a gathering of approximately two thousand scientists.1 The carbon-14 dating involved precautions against contamination.Several tests were done by the University of Georgia using accelerator mass spectrometry.Another question that might come up with respect to these studies is the issue of contamination.If young organic material became mixed with the dinosaur material that was carbon-14 dated, then the younger material would skew the result to a younger age.Diamonds supposedly formed even further back in the past than dinosaurs —over a billion years ago.
