How do fossils help geologists?
Fossils help geologists discover new species. Fossils also explain and show the age of the specimen and change in life forms.
Why are index fossils so important to geologists?
Index fossils are very important to geologists because they identify geological time periods. Index fossils are found within a specific layer of rock- So when one finds the age of the rock layer, that is also the age of the index fossil.

It gives information to scientists about the past. It also provides a reference of time throught rock layers. It can identify and define geological periods of time.
How do geologists use the column?
