Dating a dinosaur bone
* Three Related Lines of Evidence Shoring Up the Young Earth Interpretation: The interaction between dinosaur soft tissue, unracemized left-handed amino acids, and Carbon 14 must all be explained to understand the true age of the geologic column.
(1) Significant amounts of short-lived 14c, in quantities far above the least count (margin of error) of our state-of-the-art equipment, is measured in diamonds, dinosaur fossils, marble, giant extinct aquatic lizard, natural gas, coal (and see this paper at Science Direct), and reportedly in oil.
However, terrestrial radioactivity is concentrated, with the vast majority of it occurring in the continental crust.
Because modern carbon exists in significant quantities, far above the reliability threshold of the AMS labs doing the tests, these results can : Unexpected C14 is found in specimens worldwide, yet 14c production (in the ground as compared to in the atmosphere) requires a lot of nearby radioactivity to produce appreciable amounts of 14c by neutron capture.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.The finding has caused a significant stir in scientific circles.There has been wide agreement among paleontologists that dinosaurs became extinct roughly 65.5 million years ago.
