That means they don't really know how old their rocks actually are.

The key in relative dating is to find an ordered sequence.

Sort of an offshoot of stratigraphic succession is fossil succession, or a method in which scientists compare fossils in different rock strata to determine the relative ages of each.In fact, Paul already knows that coelophysis lived around 200 million years ago, while iguanodon lived around 150 million years ago.So, what if Paul found that superus awesomus dinosaur fossil in this middle layer?Scientists know that the layers they see in sedimentary rock were built up in a certain order, from bottom to top.

When they find a section of rock that has a lot of different strata, they can assume that the bottom-most layer is the oldest and the top-most layer is the youngest.The most common form of relative dating is called stratigraphic succession.
