DATING FOSSILS - Fact Monster A fossil will always be younger than fossils in the beds beneath it and this is called the principle of superposition. Rock layers of a cliff face In an undisturbed sequence of rocks, such as in a cliff face, it is easy to get a rough idea of the ages of the individual strata – the oldest lies at the bottom and the youngest lies at the top.

Dating Fossils – How Are Fossils Dated? - While people are most familiar with carbon dating, carbon dating is rarely applicable to fossils. Carbon-14, the radioactive isotope of carbon used in carbon dating has a half-life of 5730 years, so it decays too fast. It can only be used to date fossils younger than about 75,000 years. Potassium-40 on the other hand has a half like of billion years and is common in rocks and minerals. This makes it ideal for dating much older rocks and fossils.
