Carbon dating dinosaur
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.(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.With the scientific breakthroughs and discoveries coming in daily, this is a great time to be alive!* Update: At creation.com/c14-dinos, see the great summary of this presentation from Carl Wieland, president of Creation Ministries International.However, scientists are consistently finding 14c everywhere it shouldn't be.As reported in 2011 in the journal PLo S One, in an allegedly 80-million year old mosasaur.Comparable amounts of radiocarbon showed up in almost 50 total samples.Defenders of evolutionary time scales will have to assert that the radiocarbon all came from some sort of contamination, where recent or modern carbon somehow crept into all these samples.
The last article in the issue presents never-before-seen carbon dates for 14 different fossils, including dinosaurs.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.
