Radiometric dating is the most reliable, and carbon (with its ~50ky limit, due to a half-life of 5, years) is only the best-known method. There are many other radioisotopes with much longer half-lives found in both fossils and the rocks in which they’re buried.
This calls the whole radiometric dating scheme into serious question. Geologists assert that older dates are found deeper down in the geologic column, which they take as evidence that radiometric dating is giving true ages, since it is apparent that rocks that are deeper must be older.
Jun 01, · As potassium decays, it turns into argon. But unlike radiocarbon dating, the older the sample, the more accurate the dating — researchers typically use these methods on finds at least , years old.

Radiocarbon dating (also referred to as carbon dating or carbon dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon.. The method was developed in the late s at the University of Chicago by Willard Libby, who received the Nobel Prize in Chemistry for his work in
Relative Dating Methods. The simplest and most intuitive way of dating geological features is to look at the relationships between them. There are a few simple rules for doing this, some of which we’ve already looked at in Chapter 6. For example, the principle of superposition states that sedimentary layers are deposited in sequence, and, unless the entire sequence has been turned over by tectonic .
Using relative dating the fossil is compared to something for which an age is already known. For example if you have a fossil trilobite and it was found in the Wheeler Formation. The Wheeler Formation has been previously dated to approximately million year old, so we know the trilobite is also about million years old.

RELATIVE AGE. DETERMINING RELATIVE AGE FROM THE ROCK RECORD. THE LAW OF SUPERPOSITION. The Law of Superposition states that in a layered, depositional sequence (such as a series of sedimentary beds or lava flows), the material on which any layer is deposited is older than the layer itself. Thus, the layers are successively younger, going from bottom to top.
