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 fossils are helpful to geologist because they reveal the relative ages of the rock layers in which they occur?
Those types of fossils are called index fossils.
How can fossil correlation be used to determine the ages of rock layer?
dont care
How are fossils organized in the fossil record?
Fossils are arragned in sequential order because of the buildup of material over the top of them for millions of years. Hence, the oldest will be on the bottom. This can be altered by certain geoligical processes and will depend on the rockbed and formation present in the area.
How does the law of superposition allow paleontologist to assign relative ages to 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 sometimes use an easily recognized species called?
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.
What does relative dating mean in biology?
Scientists can compare the ages of the fossils in one layer of the earth and then compare thoes to fossils in another layer of the earth. The one that is deeper is most likely to be older:)
Can fossils be used to determine the relative ages of rocks layers?
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.

How does relative dating and absolute dating help scientists assemble a fossil record for an area?
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.
How can fossils be used to determine the relative ages of rock?
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.
How the relative age of a fossil is determined by studying layers of rock?
It is determined because in layers of rocks the fossils are found so the layers of rocks give information to the scientist about the age of a fossil so like that the relative age of a fossil is determined.
What are relative fossils?
Answer: The age of a rock compared to the ages of the rock layers.
How can fossils be uesed to compare the ages of different rocks?
