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.
What else can I help you with?
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.
Fossils such as trilobites that can be used to estabish the age of rocks are called?
I think they are called Index Fossils...
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.
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
How is carbon-14 dating used to determine the age of dinosaur fossils?
Carbon-14 dating is not used to determine the age of dinosaur fossils. Instead, scientists use other methods like radiometric dating, such as uranium-lead dating or potassium-argon dating, to estimate the age of dinosaur fossils. These methods rely on the decay of radioactive isotopes in the fossils to calculate their age.
What is a way to determine the actual age of fossils?
Scientists can determine the actual age of fossils using radiometric dating methods, such as carbon-14 dating for relatively young fossils or uranium-lead dating for older fossils. These methods measure the decay of radioactive isotopes in the fossil to calculate its age with a high degree of accuracy.
How index fossils can be used to determine the age of rocks?
Index fossils are used to date rocks by correlating the fossils found in the rock layers with known ages of those fossils. Index fossils are distinctive, widespread, and lived for a relatively short period of time. By identifying these fossils in a rock layer, scientists can infer the age of the rock based on the age range of the known fossil.
What are two of determining a fossils age?
The two methods are "RELATIVE DATING" and "ABSOLUTE DATING". :)
Index fossils allow geologists to?
Index fossils help geologists determine the relative age of rock layers by comparing the fossils found in them to known ages of fossils. By identifying specific index fossils, geologists can correlate rock layers from different locations and help determine the chronological order of events in Earth's history.
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 are index fossils and how are they used to determine the absolute age of sedimentary rock?
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.
True or False Fossils may be dated by either the relative dating method which determines the relative order of fossils or by the absolute dating method which uses radioactive isotopes?
True. Fossils can be dated using both relative dating methods, which determine the sequence of events in which fossils occurred, and absolute dating methods, which rely on radioactive isotopes to calculate the age of fossils.
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.
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.
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 is carbon dating used to determine the age of dinosaur fossils?
Carbon dating is not typically used to determine the age of dinosaur fossils because dinosaurs lived millions of years ago, beyond the range of carbon dating which is effective up to about 50,000 years. Instead, other methods like radiometric dating are used to determine the age of dinosaur fossils by measuring the decay of radioactive isotopes in the fossils.
