What organism alive today is related to the trilobite?
Trilobites are thought to have been a marine organism because the fossils are found in rocks that contain other salt-water animals. Trilobites are thought to be one of the earliest groups of arthropods.
Fossils are found only in .?
Sedimentary rocks

What fossils are most useful for correlation tend to be?

Why can trilobites be used as index fossils?
Trilobites: The Index Fossil There are many thousands of known species of trilobite fossils found worldwide. Trilobites are considered to be good index fossils because they evolved so rapidly, and this allows geologists the ability to date the rocks in which the trilobites are found. The discovery of trilobites is second only to the discovery of dinosaurs, and new species of trilobites are still being discovered today.
What are index fossils and how are they used to determine the absolute age of sedimentary rocks?
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.

because they are rocks and fossils dont belong in rocks and fossils can be made things an rocks cant :(...
What can be used to date fossils in rocks to give an approximate age?
The study of strata is called stratigraphy. Stratigraphy can be used to determine an approximate age of fossils in rocks.
