These fossils have this name because they are good indicators about a particular time period. The scientists are able to determine a geological period without even examining the layers, but just by simply finding these fossils.
There are several characteristics that make the index fossils special. They are found over very large area. Not just that they are found in lot of places, but they are also abundant. They existed only for a limited time period, thus being good indicator of a particular geological period. They are easy to distinguish from the other fossils.

- trace fossils
- molds and casts
- petrified fossils
- carbon films
- preserved remains
