The second method is called absolute dating and is done by analysing the amount of radioactive decay in the minerals of the rocks. 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. Sometimes, scientists already know the age of the fossil because fossils of the same species have been found elsewhere and it has been possible to establish accurately from those when the dinosaur lived.
