Geologists look for index fossils in the sedimentary rock to help determine its age. Index fossils are of organisms that were widespread and only existed during a specific slice of geologic time. Finding an index fossil in a rock means that the rock dates to that specific slice of time.

How are fossils important to scientist?
They tell us about past environments and may be used to date rocks on a relative time scale.
Can fossils be used to determine the relative ages of rocks layers?
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.
What kind of rock layers did index fossil date?
index fossils are used to date the rock layers they are found incc
Fossils such as trilobites that can be used to estabish the age of rocks are called?
I think they are called Index Fossils...
Why aren't fossils found in ingenious rocks?
because they are rocks and fossils dont belong in rocks and fossils can be made things an rocks cant :(...
