Index fossils are species that lived for a short period of time but were widespread geographically. They can be used to help date the age of rock layers since they are found in many different locations around the world for a specific time period. In the case of ammonites, they existed for a relatively limited period of time, making them a good example of an index fossil. To determine this answer, you would need to study the fossil record and look for evidence that ammonites were widespread but existed for only a specific period of time.
