As reported in 2011 in the journal PLo S One, in an allegedly 80-million year old mosasaur.
As reported in the journal Radiocarbon in natural gas, coal, oil and other petroleum products.
Thus, where researchers find , "There is no known natural mechanism by which collagen may be altered to yield a false age." And as of 2019, there is still no known mechanism to contaminate collagen with modern carbon.
As a result of decomposition, to the extent that original carbon atoms were falling out of the tissue (so to speak), then to that extent you would no longer have collagen; rather, to that extent you would have humic acid.
Decomposing collagen cannot be "repaired" by free carbon atoms happening upon the decomposition.
Further, this 2017 paper in , Carbon fixation from mineral carbonates, confirms that cynobacteria in fossils get "virtually all" of their carbon from the bone substrate they are feeding on!
Therefore they cannot "contaminate" the 14c results because they will carbon "date" the same as the bone itself, for their percentage of modern carbon is identical to that of the bone.
