It is calibrated by C14 dating, and the ages given by the two methods are in close agreement after such calibration.

If there had been contamination, then it would have introduced other substances into the soft tissue.Robert Service wrote in Science: The [soft tissue fossil] claims were met with howls of skepticism from biochemists and paleontologists who saw no way that fragile organic molecules could survive for tens of millions of years, and wondered whether her samples were contaminated with modern proteins.Ancient protein specialist Michael Collins noted, “Proteins decay in an orderly fashion. This shows that there are many such finds of protein in fossil specimens, and also that experts in the field have trouble seeing how proteins could survive in bone for millions of years.All these results have been reported in the conventional scientific literature. Pieces of fossilized wood in Oligocene, Eocene, Creta- ceous, Jurassic, Triassic, and Permian rock layers supposedly 32–250 million years old all contain meas- urable radiocarbon, equivalent to “ages” of 20,700 to 44,700 years. Similarly, carefully sampled pieces of coal from ten U. coal beds, ranging from Eocene to Pennsylvanian and supposedly 40–320 million years old, all contained similar radiocarbon levels equivalent to “ages” of 48,000 to 50,000 years.Even fossilized ammonite shells found alongside fossilized wood in a Cretaceous layer, supposedly 112–120 million years old, contained measurable radiocarbon equivalent to “ages” of 36,400 to 48,710 years.
