index fossils are useful for figuring out the age of a set of disturbed rock layers by index fossils are used to determine when rock layers were formed so if they were used to figure out the age of a set of disturbed rock layers than they can also figure out when they were formed .

Why are index fossils are more useful to paleontologists than many other fossils?
im trying to figure that out myself
What are index fossils useful for?
Because organisms that became index fossils lived only during specific intervals of geologic time, geologists can estimate the ages of rock layers based on the particular index fossils they contain.

How are index fossils useful to geologist?
Index fossils provide a reference of time throughout rock layers. In order to be a good index fossil, the life form must have lived for a short and specific amount of time and must have existed over a large area. Index fossils serve as a reference to geologists in correlating rock layers. They can match up (or correlate) the index fossils which helps them match up (or correlate) the rock layers.
How can index fossils help scientists figure out the ages of rock layers?
index fossils are important for index fossils because they use them to match up rock layers in certain locations that may be far apart! they are ALSO important to scientists because it helps them with relative age!.. HOPE THIS HELPED:]
Why are sedimentary rocks useful to scientists'?
Mainly because the fossils of plants and animals preserved in the sediment layers allow dating of events that happened before humans existed.
What fossils are useful in determining the relative age of rocks?
Index fossils
How is fossils useful?
they are useful for alot of things like petrol
How are the characteristics of index fossils useful to geologists?
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.
Why are index fossils more useful then other fossils to paleontologist?
It is because the index fossils has better minds than the paleontologist.
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.
What fossils are most useful for correlation tend to be?
Fossils that are the most useful for correlation tend to be found in various types of rocks, are widespread, and easy to recognize. One rock type where fossils are found is sedimentary rocks.
