Question: How are fossils found and how are they dated?

There are two main methods determining a fossils age, relative dating and absolute dating. Absolute dating is used to determine a precise age of a fossil by using radiometric dating to measure the decay of isotopes, either within the fossil or more often the rocks associated with it.There are two main methods determining a fossils age, relative dating and absolute dating

How are fossils usually dated?

To establish the age of a rock or a fossil, researchers use some type of clock to determine the date it was formed. Geologists commonly use radiometric dating methods, based on the natural radioactive decay of certain elements such as potassium and carbon, as reliable clocks to date ancient events.

What is the most accurate method of dating fossils?

One of the most widely used and well-known absolute dating techniques is carbon-14 (or radiocarbon) dating, which is used to date organic remains. This is a radiometric technique, since it is based on radioactive decay.
