Radiometric dating The Age of Dinosaurs was so many millions of years ago that it is very difficult to date exactly.

This considers the positions of the different rocks in sequence in relation to each other and the different types of fossil that are found in them. The second method is called absolute dating and is done by analysing the amount of radioactive decay in the minerals of the rocks.
