Quizplus · Accepted Answer

The concept of index fossils is associated with the principle of faunal succession. This principle states that assemblages of fossils in rock layers can be correlated with one another and with other rock layers based on the sequence in which they occurred. Index fossils are fossils of organisms that were widespread and lived during a specific period of time. By identifying and dating index fossils, geologists can determine the relative age of rock layers and the timing of past events.
