Describe how geologists use an index fossil and list the three characteristics of a good index fossil?

Geologists use index fossils to date the rock layers they are found in and to correlate similar rock layers in different locations. Three characteristics of a good index fossil are: widespread distribution, short duration in the geologic time scale, and easily recognizable features.

What characteristics must a fossil have to be useful as an index fossil?

An index fossil must be of a rapidly evolving organism that only existed for a specific period of time, is easily recognizable, is abundantly preserved, and was widespread geographically. Most index fossils are therefore of marine organisms.

What 3 requirements do index fossils have?

Index fossils must be widespread geographically, have a short stratigraphic range, and be easily identifiable. These characteristics make them useful for determining the relative ages of rock layers and correlating them across different locations.

What fossil used to compare the relative ages of fossils?

An index fossil. An index fossil's age is known, allowing scientists to know the relative age of other fossils based on their position relative to the index fossil. (Ex. If a fossil is deeper in the earth, it is older than the index fossil)

What is the relative age of a fossil that can be determined by comparing it to an index fossil is called?

The relative age of a fossil that can be determined by comparing it to an index fossil is called biostratigraphic dating. This method relies on the known age range of the index fossil to estimate the relative age of the fossil being studied.
