it can be matched to another fossil that can be visually identified as being from the same animal, and then can be matched up to the period the animal lived...or the second method would be to do a radio carbon dating test....but the fossil would have to be fairly old because the carbon dating can tell you how old something is within a few thousand years.

add. Carbon dating has a ceiling of about 60 000 years, which is pretty young for rocks. The half-life of 14C is about 5700 years.
But there are several longer-lived radioactive decay processes with adequate resolution for all of geology. K-Ar, Rb-Sr, U-Pb, and so on.
Some half-lives (Bi) exceed even the age of the Universe!
But as these dating methods are fairly expensive (think of the price of a car) it is more common to use existing fossil chronologies. Or stratigraphic methods.

What two methods are used to determine the age of a rock?
The two methods are relative dating and radioactive dating for fossils. I think it's the same for rocks.
Do index fossils tell the relative or absolute age of fossils?
Index fossils can be used to help determine the relative age of rock layers. Index fossils are from species that only existed for a short time. Index fossils are found in rock layers. Trilobites and Graptolites are index fossils.
Fossils such as trilobites that can be used to estabish the age of rocks are called?
I think they are called Index Fossils...
How are fossils used in determining the age of the Earth?
Index
What is the age of fossils that can be measured by what dating?
Fossils themselves can very rarely be dated by any means...their age is usually judged by the geological assessment of the area and layer in which they are found
What are two of determining a fossils age?
The two methods are "RELATIVE DATING" and "ABSOLUTE DATING". :)
How do you tell how old sediments are?
Sediments that have lithified, or become sedimentary rock, often contain marine and non-marine animal and plant fossils. These fossils are of organisms that existed only in certain time periods in Earth's history. Identifying the fossils reveals a general age of the rock, give or take some tens of millions of years. Actual age can be roughly estimated by means of radiometric dating.
What is a geochronologist?
Geochronology is the method of determining the absolute age of rocks, using radiometric methods.

How can the age of a rock be related to fossils?
If a lava flow or bed of volcanic ash was dated using isotopic dating methods and fossils were found in a sedimentary rock beneath the volcanic rock, it can be surmised that the fossils were older than the lava or ash. If the same species of fossils were found in another part of the world it would make sense that the rocks there were the same age as previous fossils. By cross checking with many other areas with other volcanic rocks, it can be found that all the rocks around the world containing those fossils were of a similar age.
The advantages and disadvantages of Relative Dating Methods?
Relative dating methods provide a chronological framework by determining the relative order of artifacts or events, making it useful for understanding the sequence of geological and archaeological events. However, they do not provide specific ages and rely on the principle of superposition, which may not always accurately reflect the true chronological order. Furthermore, relative dating methods are unable to provide precise dates, making it challenging to compare events across different regions.
What do scientists use to date exact age of fossils?
For relatively recent fossils, dating by carbon 14 is the most accurate method. For older fossils it is necessary to analyse the geological layer in which they are found; fossils located in an undisturbed geological layer of a certain age, are the same age as the layer in which they are found, necessarily.
How did they find out that Stegosaurus lived in 145 and 155 million years?
Stegosaurus fossils actually date to between 155 and 150 million years ago. Using various methods, paleontologists are able to determine the age of rocks. Then they know that fossils in those rocks are the same age as the rocks. In the case of Stegosaurus, they know the rocks are between 155 and 150 million years old, and they know the Stegosaurus fossils are the same age.
What are the difference between reworked fossils and leaked fossils?
From the law of faunal succession,older beds are characterized by fossils of older age and the younger beds are characterized by younger age fossils.But in some exceptional condition the younger fossils are reported in the older formation and those are termed as leaked fossils. whereas,Fossils of older age occur in younger rock are known as reworked fossils.They are derived from the older rocks by reworking ad recycling of sediments.
What fossils are useful in determining the relative age of rocks?
Index fossils
To determine the absolute age of rocks and fossils geologists use?
They would look for evidence of index fossils, those of certain rapidly evolving creatures that lived during a specific time period. This method is called relative dating. For a closer estimation they would be able to date the rock using radiometric techniques that base its age on the degree of isotope decay . This method would reveal the much more specific absolute age.
Can fossil age determine organism changes related to the time scale?
The discovery of a fossil's age can be determined through methods involving radiometric dating. Fossils must then be compared to other organisms of that time period to determine changes to it.
