When an organism dies it ceases to replenish carbon in its tissues and the decay of carbon 14 to nitrogen 14 changes the ratio of carbon 12 to carbon 14.Experts can compare the ratio of carbon 12 to carbon 14 in dead material to the ratio when the organism was alive to estimate the date of its death.Dates for carbon material can often be independently verified by testing something that is known historically, from records of human observations.Dating with C is possible for up to “50 to 80 thousand years” before the present, yet we need to remember that these older dates are under the assumption that there never was any worldwide flood.Carbon is naturally in all living organisms and is replenished in the tissues by eating other organisms or by breathing air that contains carbon.At any particular time all living organisms have approximately the same ratio of carbon 12 to carbon 14 in their tissues.In the case of radiocarbon dating, the half-life of carbon 14 is 5,730 years.This half life is a relatively small number, which means that carbon 14 dating is not particularly helpful for very recent deaths and deaths more than 50,000 years ago.
Radiocarbon Dating Reliability Radiocarbon dating is the most accurate and most verifiable of the radiometric dating systems.
I saw problems with the 1992 article, more than just its being outdated, but we need to move on.
The proclamation that shellac had contaminated dinosaur remains from the Carnegie Museum of Natural History is irrelevant to the many tests on dinosaur bones since 1990.
A 1990 experiment that involved radiocarbon dating of pieces from two dinosaur bones—that test will not be covered, for it involved a controversy regarding a report of shellac that may have contaminated one of the two sample sources.
Today, I did a Google search with “radiocarbon dating dinosaurs” (not in quotes).
