Scientists are always spouting information about the ages of rocks and fossils. Well, they figure it out using two different methods: relative dating and numerical dating.Let's find out more about these geological dating methods in order to understand how Paul the Paleontologist can be so sure about the age of his dinosaur fossils.

In this method, scientists compare different layers of rock to determine an ordered sequence of events in geologic history.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.That means they don't really know how old their rocks actually are.The key in relative dating is to find an ordered sequence.Again, this doesn't tell them exactly how old the layers are, but it does give them an idea of the ordered sequence of events that occurred over the history of that geologic formation.

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.

Scientists piece together a story of how one event came before or after another.

Relative dating cannot tell us the actual age of a rock; it can only tell us whether one rock is older or younger than another.

Which of these does a better job of describing my age? So, in both geology and paleontology, we want to be able to point to an object and say exactly how old it is.

To do that, we have to learn a little bit about radioactive decay.

If I told you that I was 30 years old, that number would be my numerical age.

    I’m in a relationship with kids and I tend to consider myself as being “in crisis”. I’ve had platonic, friendly, love relationships, in different places.
