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

Scientists use two kinds of dating techniques to work out the age of rocks and fossils. 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.
