Radiocarbon dating dinosaurs

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.

Thus the radiocarbon content of diamonds is all the more compelling and important, and especially when the specimens are mined from a quarter-of-a-mile below the surface, insulated from our 14c-bearing atmosphere.* Carbon-14 is Everywhere so it Can't Be an Anomaly: Carbon-14 doesn't lie. And it's so unstable that all 14c atoms in a sample would radioactively decay in far less than a million years.So, such radiocarbon in allegedly older samples could theoretically come from a secondary source like contamination, background noise, or neutron capture. For example, living bacteria might infest a dinosaur bone but the journal reports that this doesn't affect its carbon date because the bacteria doesn't feed on the 14c in the atmosphere but in the bone!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.
