index 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)

The term you are looking for is "biostratigraphy." This process involves comparing the fossil assemblages in different rock sequences to establish correlations and determine the relative ages of the rocks. By analyzing the fossils found in these rock layers, geologists can create a chronological framework for different areas.
Those types of fossils are called index fossils.
The law of superposition states that the lower down the layer of rock (also called strata) in the ground, the older it is. Therefore, if the fossil is located in a specific strata that is a certain depth beneath the ground it is conclusive as to about how old the fossil is.

To compare the relative ages of fossils, scientists use an early recognized species called an index fossil. An index fossil must have existed for a short period time and must have covered a wide geographical range.

fossils can be used to determine the relative age of rock layer by using the classification of fossils to find the relative ages of rocks in which fossils are found. :] hoped i helped you out.
A fossil used to date surrounding rock layers is called a index fossil. Index fossils are particularly useful for determining the relative ages of rock layers in different locations.
Relative dating in biology refers to estimating the age of a fossil or rock layer based on its position relative to other fossils or rock layers. It does not provide an exact age, but rather an estimation of the order of events. This method relies on principles like superposition and stratigraphy to determine the relative age of different geological features.

Relative dating is the science determining the relative order of past events, without necessarily determining their absolute age Absolute dating is the process of determining an approximate computed age in archaeology and geology.
If we know the age the respective organism is known to have occupied a certain region in the geologic past we can then correlate that to the rock its fossil was found in and consequently deduce the rock's relative age.
Answer: The age of a rock compared to the ages of the rock layers.
Using multiple fossils allows for better accuracy in determining the relative age of a rock unit because different fossils may have existed during different time periods. By examining a variety of fossils, scientists can cross-reference their ages and establish a more precise relative age for the rock unit.
