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. The first method is called relative dating. 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.
Radiometric Age Dating
Age Of The Earth
Geologists often need to know the age of material that they find. They use absolute dating methods, sometimes called numerical dating, to give rocks an actual date, or date range, in number of years. This is different to relative dating, which only puts geological events in time order. Most absolute dates for rocks are obtained with radiometric methods. These use radioactive minerals in rocks as geological clocks.

Can we determine the age of the earth, and if so, how? Scientists generally agree that the answer to the riddle of the age of the earth is carefully concealed within the earth's crust. Thus, the geologic timescale and radiometric dating have been developed in an effort to determine the age of the earth. The older of the two dating methods, the geologic timescale, is actually a circular argument and is therefore considered by many scholars to be weak. Nevertheless, the geologic timescale was thought to have been redeemed and refined with the advent of radiometric dating.
