So if a researcher can verify that he has a sample that has been purified to 99% collagen, for example, then he can be sure that all the carbon in that 99% of the sample is original.

Carbon dating has a certain margin of error, usually depending on the age and material of the sample used.

* Carbon 14 in Dinosaurs at Singapore's American Geophysical Conference: On how to date a dinosaur, Real Science Radio's Bob Enyart interviews Hugh Miller, a member of the international scientific team that presented at the 2012 AGU geophysical conference in Singapore, the carbon dating results from five respected laboratories around the world of bones from ten dinosaurs (from the Gobi Desert in China, from Europe, Alaska, Texas, and Montana). Yet each of these dinosaurs had plenty of radiocarbon (as expected in that virtually every relevant peer-reviewed paper on the topic confirms the presence of endogenous soft tissue in fossils; see Dinosaur Soft Tissue.com).

With the scientific breakthroughs and discoveries coming in daily, this is a great time to be alive!

(See below, 42 minutes into Paul Giem's 2013 presentation.) If the contamination occurred 12,000 years ago, 10% of the bone would have to be replaced; 18,000 years ago, 20%; if it occurred 24,000 years ago, 40% of the bone would have had to be replaced, and if (in the evolutionary perspective) a mere 30,000 years ago, 80% of the bone would have to be replace by a contamination process.

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.

Because radiocarbon exists in significant quantities, far above the least count (margin of error) with our state-of-the-art AMS labs doing the tests, these results can !

And as reported at Science Direct, short-lived 14c is regularly found even in supposedly billion-year-old diamonds!

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.

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.
