I can answer part of this question. If they can scientists use carbon dating to find the closest age of the fossil. If carbon dating is not possible they use a different technique such as this: If they look at the layers of the rocks, the rocks before and after the layer of rock the fossil was found in, can show an estimate of how old the fossil can be if they know the age of the rock layers before and after its layer.

How can index fossils be used to date rock?
Because if you know how old the fossil is, and you find the fossil inside a rock, you know that rock has a maxium age corresponding with the age of the fossil.
A fossil that is found in the rock layers of only one geologic age and that is used to establish the age of the rock layers?
An index fossil.
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 Specific age of a rock or fossil?
absolute age
What are the preserved remains of living organisms arranged by age?
fossil or fossil record hope this helps -sj
What do scientists use fossil evidence to prove?
Evolution
How is the absolute age of the fossil different from the relative age?
Absolute age is the definite age of a fossil, while relative age is an estimated age according to the sediments and other fossils around the fossil.
If the relative age of a fossil is known what else is known?
The age of rock surrounding the fossil.
Can a credit card prove your age?
No. A credit card does not prove age or identity.
How scientists estimate the age in years of a fossil?
Scientists can use carbon dating to determine the age of a fossil.

What are 3 things can fossil tell us?
It tells you the Age, Place is was from and the Species of the Fossil
What is the relative age of a fossil starfish?
the relative age of the rock where it was found.
What is the Specific age of a rock or fossil?
absolute age
What are the preserved remains of living organisms arranged by age?
