Carbometric dating dinosaur
) 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.
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.
) Both mathematical analysis of the data, and the nature of some of the specimens, indicate that contamination does not solve the radiocarbon problem for old-earth geologists.: While dinosaur bones, coal, and other specimens could easily be contaminated, diamonds, the hardest naturally occurring substance in the world are naturally resistant to contamination.* 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!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!
