Although most attention in today's world focuses on dinosaurs and why they became extinct, the world of paleontology includes many other interesting organisms which tell us about Earth's past history.The study of fossils and the exploration of what they tell scientists about past climates and environments on Earth can be an interesting study for students of all ages.One outcrop shows layers from one geologic time period, while the other outcrop represents a different time. Can he put the pieces together to make the story more complete? Let's find out how scientists deal with this common problem by using the fossils inside the rocks.

Sedimentary rocks can be dated using radioactive carbon, but because carbon decays relatively quickly, this only works for rocks younger than about 50 thousand years.

We talked about relative dating of rocks and how scientists use stratigraphic succession to compare the ages of different rock layers.

You should already understand that the lower rock strata are generally older than the strata found higher up in the rock.

But this sediment doesn't typically include the necessary isotopes in measurable amounts.

Fossils can't form in the igneous rock that usually does contain the isotopes.
