Index fossils are distinctive fossils that existed for only short time periods. They are used to

• alphabetized the names of new fossils that are found

• indicate the age of certain layers of sedimentary rocks

• determine the social structure of the larger dinosaurs of the Jurassic period

Why are index fossils useful to geologists?

• They tell the relative age of the rock in which they occur.

• They tell the absolute age of the rock in which they occur.

• They tell the ages of many different rock layers.

The Law of Superposition states:

• Oldest is on the top layer, youngest is on the bottom

• Oldest in the middle layers, youngest is on the bottom

• Oldest is on the bottom layer, youngest is on the top

• All of the rock layers are the same age
