Does carbon dating work dinosaurs


And consider this from a peer-reviewed paper in a respected scientific journal, "at a constant 10°C (the approximate mean annual air temperature in Britain today) it will take between 0.2 and 0.7 Ma for levels of collagen to fall to 1% of their original concentration in an optimal burial environment." * Getting Graded: An expert on radiocarbon dating, long-time assistant professor at Loma Linda University, Dr. The teacher corrected a couple points and clarified a few others.



Paul Giem writes that, "since nitrogen creates carbon-14 from neutrons 110,000 times more easily than does carbon," samples with even tiny amounts of nitrogen would dramatically increase carbon dates, such that, "If neutron capture is a significant source of carbon-14 in a given sample, radiocarbon dates should vary wildly with the nitrogen content of the sample." Giem adds, "I know of no such data.": Recognizing that crustal radioactivity is generally relatively scare (as documented in this U. Therefore, there would have to be thousands of times more uranium, thorium, etc.However, scientists are consistently finding C-14, as reported in 2011 in the journal PLo S One for an allegedly 80-million year old mosasaur, and as reported elsewhere in natural gas, limestone, fossil wood, coal, oil, graphite, marble, the ten dinosaurs described above, and even in supposedly billion-year-old diamonds.A secondary assumption by old-earth scientists proposes that the C-14 in diamonds (coal, etc.) must have come from N-14 (or C-13, etc.) and neutron capture.Many such lines of evidence (multiplying as at youngearth.com) undermine the claim by old-earth geologists that the plentiful 14c in "ancient" specimens must come from contamination or neutron capture (see below), and this evidence helps to confirm the young earth interpretation of the data below.

* Carbon 14 in Dinosaurs at the American Geophysical Conference in Singapore: On how to date a dinosaur, Real Science Radio's Bob Enyart interviews Hugh Miller, a member of the international scientific team that presented at the 2012 AGU geophysical conference in Singapore, the carbon dating results from five respected laboratories around the world of bones from ten dinosaurs (from the Gobi Desert in China, from Europe, Alaska, Texas, and Montana). Yet each of these dinosaurs had plenty of radiocarbon (as expected in that virtually every relevant peer-reviewed paper on the topic confirms the presence of endogenous soft tissue in fossils; see Dinosaur Soft Tissue.com).

Of course we're hoping that now that we've corrected the material below, that this is solid A work!

    Mar 11, 2015. Radiocarbon dating doesn't work well on objects much older than twenty thousand years, because such objects have so little C-14 left that their beta radiation is swamped out by the background radiation of cosmic rays and potassium-40 K-40 decay. Younger objects can easily be dated, because they still.…

    Jun 5, 2012. Answer by John Mackay. Many of you will realise that this is a totally misplaced question, albeit probably a genuine one. So we will take the opportunity of reminding folks that Carbon 14 dating, even if it did work, wouldn't give billions of years for anything. Carbon 14 is a short lived radioactive element with.…

    Oct 26, 2015. Instead, other methods are used to work out a fossil's age. These include radiometric dating of volcanic layers above or below the fossils or by comparisons to similar rocks and fossils of known ages. Why date a fossil? Knowing when a dinosaur or other animal lived is important because it helps us place.…

    It is common practice to determine the age of bones by radiocarbon RC dating of extracted bone collagen but not of dinosaurs because they are assumed to have. 19 Thus Lovering et al. concluded "Although RC ages were inconsistent, field work on geology of australite occurrences favored the 'younger' C-14 age of.…

    Dinosaurs went extinct 65 million years ago. To determine the age of a dinosaur fossil, carbon dating can never be used. Carbon-14 only works for fossils less than 75,000 years old. By the time a dinosaur fossil was found, any carbon-14 the organism would have taken up and incorporated into its tissues during its life.…

    Carbon-14, Radiometric Dating and Index Fossils. Carbon dating is used to determine the age of biological artifacts up to 50,000 years old. This technique is widely used on recent artifacts, but educators and students alike should note that this technique will not work on older fossils like those of the dinosaurs alleged to be.…
