The second method is called absolute dating and is done by analysing the amount of radioactive decay in the minerals of the rocks dating a dinosaur skeleton scientists find out the age of a dinosaur fossil by dating not only the rocks in which it lies, but those below and above it. Other articles where absolute dating is discussed: dating: absolute dating: although relative ages can generally be established on a local scale, the events recorded in rocks from different locations can be integrated into a picture of regional or global scale only if their sequence in time is firmly established.
Another absolute dating method is thermoluminescence, which dates the last time an item was heated it is the only method that can be used to date rocks, pottery and minerals for dates that are approximately between 300 to 10,000 years old.
