Fossils can also be dated using methods like potassium-argon dating, uranium-lead dating, and thorium-lead dating, which are based on the decay rates of specific radioactive isotopes found in the fossils. By measuring the amount of parent and daughter isotopes present in the fossil, scientists can determine its age.

What are two ways to date fossils?
Two ways to date fossils are relative dating, which involves determining the age of a fossil in relation to other fossils or geological layers, and absolute dating, which provides a numerical age for a fossil using techniques like radiometric dating.
Which type of dating provides an absolute age for a given fossil describe how this is done?
I think it's Radioactive dating, I've been reading for my homework and I can't seem to find carbon dating anywhere in the chapter which I've reread about 3 times so I'm going to assume its radioactive because relative dating is the estimation of a fossils age compared with other fossils.
What do paleontologists use to determine the actual age of a rock?
They use a method called Carbon Dating, which allows them to get a really precise measurement on when the rock, or fossil (usually a fossil is what they Carbon Date) was either made or destroyed. (though even when destroyed, a sample can still easily tell them what time it was from.)
Used to date fossils in rocks to give an approximate age?
Radiometric dating is used to determine the age of fossils in rocks by measuring the decay of radioactive isotopes, such as carbon-14 or uranium-238, in the fossil. By comparing the amounts of the parent and daughter isotopes present in the fossil, scientists can calculate the age of the fossil. This method provides an approximate age of the fossil based on the rate of radioactive decay.
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.
What is the most accurate way to date a fossil?
Carbon dating

How do archaeologists date fossils?
Scientists take samples of the carbon remaining in the fossil. They then use a form of carbon dating to determine its age. (it doesn't have to be a fossil, it could be any ancient remain, even a skull from fifty years ago, or a plate from the 1700's. Just wanted to clarify that a little bit more!)
What are two ways geologists determine the age of fossils?
The two methods are "RELATIVE DATING" and "ABSOLUTE DATING". :)
How the age of plant and animal fossils is determined?
The age of a plant or animal in a fossil is determined by radiocarbon dating. This means scientists measure the amount of a special type of carbon in the fossil, to determine the date.
What is the simplest dating method used by paleontologists?
Relative Dating, its where the paleontologists date the fossils according to the layer of soil that the fossil was found compared to other fossils that were carbon dated that were in the same soil layer.
Why is useful to know how much of the element carbon is in a fossil?
Carbon dating is a process that determines how old a substance is by the amount of carbon it contains. If the amount of carbon in a fossil is known, the approximate date of the fossilization of a particular substance can be determined using the known half life of carbon. This can be used to determine what time period an organism died even millions of years ago.
How far back can you date with carbon dating?
By using carbon 14 dating, scientists can date plants and animals that lived as long as 35,000 years ago.

What is the limite for carbon dating?
About 58,000 years. After that amount of time, there will no longer be enough radioactive carbon in an object to measure. However, other radiometric dating methods can date much older materials.
What isotopes is most useful for dating plant and animal remains?
CARBON DATING The most common fossil dating techniques are radiometric dating techniques. Radiometric dating uses knowledge of the decay rates of unstable ( radioactive ) nuclei to determine, by comparison with the proportion of stable nuclei in a fossil sample, the date of the introduction of the radioactive material into the live organism, especially if the isotope was ingested while the organism was alive.
