Carbon 14 not used for dating dinosaur
This makes it ideal for dating much older rocks and fossils.
Scientists can use certain types of fossils referred to as index fossils to assist in relative dating via correlation.
Index fossils are fossils that are known to only occur within a very specific age range.
However, creation scientists have carbon-dated fossils, diamonds, and coal that are all supposed to be millions of years old.
Nevertheless, they all have detectable amounts of carbon-14 in them.
Carbon-14, the radioactive isotope of carbon used in carbon dating has a half-life of 5730 years, so it decays too fast.
This means that in old-earth terminology, carbon-14 decays “quickly.” Thus, if a bone (or some other material that is made of carbon) is really millions of years old and hasn’t been contaminated, you wouldn’t expect to find any carbon-14 in it.The carbon-14 should have long since decayed to the point where it is no longer detectable, even with the best scientific instruments we have today.
The atoms in some chemical elements have different forms, called isotopes. There are two main methods determining a fossils age, relative dating and absolute dating.Relative dating is used to determine a fossils approximate age by comparing it to similar rocks and fossils of known ages.These isotopes break down at a constant rate over time through radioactive decay.By measuring the ratio of the amount of the original (parent) isotope to the amount of the (daughter) isotopes that it breaks down into an age can be determined.Potassium-40 on the other hand has a half like of 1.25 billion years and is common in rocks and minerals.
