Carbon 14 not used for dating dinosaur
Unwilling to challenge the data openly, they erased the report from public view without a word to the authors or even to the AOGS officers, until after an investigation.
Because carbon-14 decays at this constant rate, an estimate of the date at which an organism died can be made by measuring the amount of its residual radiocarbon.
For starters, it’s clearly the wrong tool for the job: Carbon 14 has a short half life and is consequently used for dating material in the thousands of years, not millions.
No dinosaur fossil has ever been found in strata younger than 65 million years old and the strata in which the fossils were found would have been dated and cross referenced using more appropriate forms of radiometric dating.
The C-14 combines with oxygen to form carbon dioxide, plants take in the radioactive carbon dioxide, animals eat the plants, and so all living things on earth have a constant level of C-14: roughly one atom in a trillion.
When an organism dies, it stops taking in carbon-14 and the carbon-14 it already contains starts to decay.

Carbon-14 is radioactive with a half-life of about 5700 years, but as C-14 atoms decay, new ones are created.
