Dating a fossil carbon 14
Even more, proteins in this tissue retain their structure.
Extraordinary efforts were made to eliminate all contamination from the measuring apparatus.
Perhaps there was less C14 produced in the past, which would imply that even the relatively young C14 dates are too old. The C14/C12 ratio of living things and organic matter on the surface of the earth is about the same as in the atmosphere because carbon is constantly exchanged between living things and the atmosphere.
After an organism dies, if it is buried and left undisturbed, the C14 in it gradually decays into nitrogen 14. Thus the ratio of C 14 to C12 in the remains of the organism gradually decreases with time.
If decay rates were faster in the past, then even the C14 dates could be too old.
These two new finds join dozens of others published over the last half-century, but evolutionary scientists still have a hard time accepting that these fossils retain original biochemicals.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.The half-life of C14 is 5730 years, although there are subtleties about how C14 ages are actually computed.
