Sequencing the rock layers will show students how paleontologists use fossils to give relative dates to rock strata.

Once students begin to grasp "relative" dating, they can extend their knowledge of geologic time by exploring radiometric dating and developing a timeline of Earth's history.

PALEONTOLOGY, AND in particular the study of dinosaurs, is an exciting topic to people of all ages.

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.

So the correct index fossil is: We can use index fossils and key beds to correlate, or match rock layers that are the same age.

By doing this we can then place other layers of rocks in order of their relative ages to find the oldest and youngest rocks in a series of outcrops.

For example if you have a fossil trilobite and it was found in the Wheeler Formation.

The Wheeler Formation has been previously dated to approximately 507 million year old, so we know the trilobite is also about 507 million years old.

(Welles, Samuel Paul, “Paleontology,” In some cases darwinists have recognized circularity as a typical problem in evolutionary models and worked to avoid it.
