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.

How is an index fossil helpful to paleontologist?
Index fossils are the remains of organisms that lived during a very specific and well-defined time span, and are able to be recognized from various, distant locations; hence, they are usually marine invertebrates like trilobites or ammonites. They are able to provide a means of dating fossils found with them or in layers above and below them.
