scientists use two kinds of dating techniques to work out the age of rocks and fossils. the second method is called absolute dating and is done by analysing the amount of radioactive decay in the minerals of the rocks. datingthere are some radioactive elements in rock that decay by giving off energy and turning into different, more stable elements. radiometric dating on rocks known to be only a few years. dinosaur print this page cite this page dating fossils dating a dinosaur skeletonrock layers of a cliff faceindex fossilsradiometric datingthe age of dinosaurs was so many millions of years ago that it is very difficult to date exactly. with this knowledge, they can place the fossils into detailed chronological sequences.
