A good index fossil lived for a short period of time so that the range of ages of the strata in which the index fossil is located is also small.
A good index fossil is found in a wide geological range. Scientists look for fossils all across the world. If a new fossil is found in the same strata as an index fossil, then the new fossil’s age can be correlated to time period during which the index fossil lived.
In order to be located in strata within differing parts of the world or a country, good index fossils have to have been abundant while on Earth.
A good index fossil needs to have definitive characteristics so that it can be easily identified by paleontologists.
A good index fossil cannot easily decompose. This would prevent the organism from becoming a fossil.
