You are dead wrong. The calcium carbonate fraction of dinosaur bone bio-apatite has NO nitrogen for changing into C-14; and, carbon 12 or 13 isotope atoms do not change into C-14 with mild neutron sources in the earth. That’s an old straw-man claim long ago refuted.This is incorrect. If the carbon is near to a radioactive mineral, say one containing Uranium, then neutrons emitted by the decaying Uranium can change Carbon atoms from normal to radioactive. This can result in the production of new radioactive Carbon many millions of years after all the original Carbon has decayed.
Sample contamination and the limits of accuracy of the measuring equipment can also be an issue.

Yet the C-14 age for the bioapatite fraction of the Triceratops and Hadrosaur femur bones were concordant with the RC age for the bone collagen from each of the sawed bones. When labs obtain concordant ages for bones by the above double check method the age is assured to be valid. Plus ALL contamination was removed by the normal acid, alkali, acid pre-treatment method before submission to AMS or Beta C-14 equipment. The acid is to remove young or old carbonates and the alkali to remove bacteria or fungus etc. - like you do when you wash your clothes, you know, **“Tide-in, dirt-out.” **
A similar objection has been raised for C-14 in coal and diamond as analysis has shown that there is sometimes a small percentage of nitrogen: This objection has been refuted by other scientists because the radiation flux and cross section of nitrogen atoms would be too small for radiation from any uranium sources to effect the age. One would have to directly irradiate the collagen from perhaps a short distance in a MAN-MADE nuclear facility to change nitrogen into C-14 and give a false young age. Therefore my challenge to the Vatican still stands: Investigate the PAS for ignoring modern lab and field research in their attempt to keep their Sacred Cow alive.
