Consider the following scenario: Paul the Paleontologist is a very famous scientist who has studied dinosaur bones all over the world.

Recently, he appeared on the evening news to talk about a new dinosaur he just discovered. Paul says he can tell from the fossils that superus awesomus lived on Earth about 175 million years ago.

Paul is super awesome, so I'm going to take him at his word.

But really, how do scientists figure out how old their dinosaur bones are?

He saw that it underwent radioactive decay, or emission of energetic particles to produce new elements.

In 1905, Ernest Rutherford figured out that we could use radiation to establish the ages of rocks.

If I told you that I was 30 years old, that number would be my numerical age.To do that, we have to learn a little bit about radioactive decay.In 1896, a French physicist named Henri Becquerel discovered radioactivity in an element called uranium.We'll explore both relative and numerical dating on our quest to understand the process of geological dating.Along the way, we'll learn how stratigraphic succession and radioactive decay contribute to the work of paleontologists.

Of course, the coelophysis, which means that coelophysis came before iguanodon.
