Carbon 14 dating the
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).
In this method, the sample is in liquid form and a scintillator is added.
This scintillator produces a flash of light when it interacts with a beta particle.
(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.throughout the earth's crust everywhere that these globally dispersed materials are found.An age could be estimated by measuring the amount of carbon-14 present in the sample and comparing this against an internationally used reference standard.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.
