Carbon dating of bacteria

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.

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.

) Anything even just one million years old should have none of this "modern" carbon.

However, scientists are consistently finding 14c everywhere it shouldn't be.

Paul Giem himself, graded the information presented below. He gave the original text (available here) a grade of A minus.

Of course we're hoping that now that we've corrected the material below, that this is solid A work!Regarding the results from the ten dinosaurs dated (as above), of course, bacteria do not make collagen.And if the 14c came from contamination, for example, one would not expect the contamination to so equally affect the bioapatite and the collagen.: Dinosaur bone showing 5pmc means that, because the 14c half-life is so brief, 5,730 years, if the radiocarbon is from contamination that occurred 6,000 years ago, a full five percent, i.e., 1/20th of the bone must have been replaced.As reported elsewhere also in limestone, fossilized wood, coal, marble, deep groundwater, geological graphite, Mesozoic-layer limestone, and the bones of dinosaurs including the ten described below.And as reported at Science Direct, short-lived 14c is regularly found even in supposedly billion-year-old diamonds!The assumption by evolutionary geophysicists proposes that the 14c in diamonds, coal, etc., must have come from neutron capture by carbon-13 or nitrogen-14.
