Radiometric dating and radiocarbon dating
So, you might ask, why is this article about carbon-14 dating of dinosaurs?Wouldn’t the dinosaurs be too old for carbon-14 dating to work on them? That statement would be true if the dinosaurs were really millions of years old.Special care was taken to prevent this kind of contamination. 10 Living animals take in carbon-14 on a regular basis.
Notice the titles of 4 and 6 correspond in both lists, which in the opinion of some, hints strongly that the list with number 5 present was an original list." href="#footnote5_a8p1ztr"Why is the information presented in the paper important?Also, this assumes that no natural process is depositing extra carbon-14 in the animal’s remains.Assuming no intrusion of carbon-14 from external sources, the existing amount of carbon-14 resident in the animal’s remains will decay, assuming the current known decay rate.Given the initial amount of carbon-14, the decay rate, and the remaining amount of carbon-14 in a fossil, the length of time it would take for the initial amount of carbon-14 to decay to the amount measured as remaining in the fossil may be calculated.Carbon-14 decays with a half-life of about 5,730 years.
