The relative age of a fossil can be determined by comparing its to other fossils within the same rock layers below younger fossils.

The relative age of a fossil can be determined by comparing its Index fossils to other fossils within the same rock layers below younger fossils.

Explanation:

Relative dating is one of the two methods used to determine the age of fossils does not determine when events occur, but it shows the order of the events as they occur. Relative dating compares similar rocks and fossils of already known ages to the ones the fossils that are yet to be determined so as to get their approximate age. The relative age of a rock is the age of that rock when compared to the ages of other rocks.

A fossil record can show the relationship that existed between different plants and animals. Often we Index fossils are used in dating other fossils found in the same strata. Index fossils point out the relative age of the layer where it is found,
