This makes it ideal for dating much older rocks and fossils. The most widely used and accepted form of absolute dating is radioactive decay dating. Finding the key bed in these situations may help determine whether the fault is a normal fault or a thrust fault.

If the fossil you are trying to date occurs alongside one of these index fossils, then the fossil you are dating must fall into the age range of the index fossil.

Since certain species of animals existed on Earth at specific times in history, the fossils or remains of such animals embedded within those successive layers of rock also help scientists determine the age of the layers. Based on principles laid out by William Smith almost a hundred years before the publication of Charles Darwin 's theory of evolutionthe principles of succession were developed independently of evolutionary thought.

Scientists can use certain types of fossils referred to as index fossils to assist in relative dating via correlation.
