This is meaningless - paleontologists do not use carbon dating to assess dinosaur fossils; dinosaurs became extinct 66 million years ago, more than a thousand times farther back than carbon dating can be used.In a classic example of irony, carbon dating was used to verify the ages of the Dead Sea Scrolls to around 2000 years ago, during the period of the Atmosphere of the Moon • Bird evolution • Creationism and social history • Dendrochronology • Evidence against a recent creation • Evolution • Fossil • Fossil fuel • Fossil record • Geologic timeline • Geology • Geomagnetism • Grand Canyon • History of the Earth • K-Pg extinction event • Lake Agassiz • List of transitional forms • Mitochondrial Eve • Paleontology • Petrified forest • Plate tectonics • Punctuated equilibrium • Radiometric dating • Recent African Origin hypothesis • Rotation of the Earth • Starlight problem • Transitional fossil • Y-chromosomal Adam • 101 evidences for a young age of the Earth and the universe • Atmosphere of the Moon • Baraminology • Biblical literalism • Borel's Law • Bumblebee argument • C-decay • Catastrophic plate tectonics • Creationist mathematics • De-evolution • Do you want to be descended from a monkey?
Beyond that timespan, the amount of the original C formed by irradiation of nitrogen by neutrons from the spontaneous fission of uranium, present in trace quantities almost everywhere.These ions are accelerated in an electric field through collimating slits and subject to a magnetic field which causes the ions to follow a curved path. By adjustment of the strength of the magnetic field and suitable placement of an ion collector, the different isotopes can be measured with precision.There are some things that affect these measurements.After the second half-life has elapsed, yet another 50% of the remaining parent isotope will decay into daughter isotopes, and so on.For all practical purposes, the original isotope is considered extinct after 6 half-life intervals. A small portion of a meteorite is vaporized in the device forming ions.
