Index fossils
Yes, fossils of species that did not change noticeably over time, known as "index fossils," can be very useful in determining the relative ages of rocks. These fossils represent specific geological periods and can be used as markers to correlate the ages of rock layers across different locations. Their presence in a particular layer indicates that the rock is from the same time period as other layers containing the same fossils, aiding in the understanding of the geological timeline. Thus, even stable species can provide valuable information for stratigraphic correlation.

Sedimentary rocks, which form in layers over time, are most likely to contain fossils that can be used to establish relative dates. Fossils found in these rocks provide a record of the organisms that lived at specific times in Earth's history, allowing scientists to determine the relative age of the rock layers.
the answer is procces of breaking down rock into smaller and smaller sediments
Relative age of the rocks and the Paleo environment.
In order to be useful in determining the relative ages of rocks, an indicator must provide different indications for rocks of different ages, right? So how could something which doesn't change over time be useful?

fossils can be used to determine the relative age of rock layer by using the classification of fossils to find the relative ages of rocks in which fossils are found. :] hoped i helped you out.
Scientists used trilobites as index fossils because they were abundant, had a wide distribution, and had a relatively short existence in the fossil record. This made them useful for correlating rock layers from different locations and determining the relative ages of the rocks.
A fault can be useful in determining the relative ages of different rock layers by showing which layers have been displaced or shifted due to tectonic forces. This can help geologists establish the sequence of events in an area's geological history.

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.

Graptolites are excellent index fossils because they have a short-lived existence in the geologic time scale and are widespread. They are useful for dating rocks and correlating layers in different locations, assisting in determining the age of rocks and reconstructing past environments.

They're useful for x-rays or looking at metals,or determining the age of rocks/fossils. (Hope it helped!😁)
