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:]
Since the 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.
Index fossils are fossils of organisms that only existed during a relatively short period of time and were found globally (widespread). Since the organism was widespread and was only around for a short time, if we know when it was around, we then know how old a rock is that contains it.
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 .
they tell the absoute age of rcoks which they occur
Index fossils can be used to help determine the relative age of rock layers. Index fossils are from species that only existed for a short time. Index fossils are found in rock layers. Trilobites and Graptolites are index fossils.

Relative dating. Paleostratigraphy correlates layers of rock using index fossils found within them.
Geologists use index fossils to define and identify geologic periods.
Those types of fossils are called index fossils.

Trilobites were rapidly evolving and widespread organisms, making them ideal index fossils.
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.
