The main isotope used for determining the age of artifacts in Archaeology is carbon 14, however there are many others.
Other radiometric methods (methods based on the decay rates of radioactive isotopes) include:
- Potassium-Argon dating - Based on the decay of potassium 40
- Uranium Series dating - Based on the decay of several isotopes, including Uranium 238 (also used in fission track dating), Uranium 235, Thorium 230 and Protactinium 231.
- Lead 210 dating - Based (unsuprisingly) on the decay of Lead 210.
A climate based method, based on the "Oxygen Isotope timescale" can be used to broadly date things and uses ratios of Oxygen 18 to Oxygen 16.

What isotope is used to date ancient artifacts such as fossils?
Carbon-14 dating is commonly used to date ancient artifacts such as fossils. This method relies on the half-life of carbon-14, which isotope decays at a known rate, to estimate the age of the artifact by measuring the remaining carbon-14 in it.
Which isotope is used to date ancient such as fossils?
The isotope of carbon is used to date the ancient fossils. Since every living creature had organic matter and carbon is an integral part of that organic matter, it is conventional to use carbon isotope.
How do scientists date the fossils and artifacts?
any other artifact or geological strata and compare it. Go to tables with similar artifacts.
How do scientists date fossils and artifacts?
Scientists date fossils and artifacts using various methods such as radiocarbon dating, potassium-argon dating, and thermoluminescence dating. These methods analyze the amount of specific isotopes present in the sample to determine its age. By comparing the ratio of isotopes to known decay rates, scientists can estimate the age of the fossil or artifact.
Give an example of an isotope used in dating old objects?
Carbon-14 is an example of an isotope used in dating old objects. It is often used in radiocarbon dating to determine the age of organic materials such as fossils or archaeological artifacts.

What are 14 used to date organic materials?
Carbon-14 dating is used to date organic materials by measuring the amount of carbon-14 remaining in a sample. Carbon-14 is a radioactive isotope that decays at a known rate, allowing scientists to determine the age of an organic material based on the ratio of carbon-14 to carbon-12. This method is commonly used in archaeology, anthropology, and geology to date ancient artifacts and fossils.
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 the two ways to date a fossil?
Radioactive isotope dating (potassium, argon) and relative dating, comparing with fossils of the same characteristics with known dates. Particularly if they are known to be 'zone fossils'
How do scientists use the halflife of radioactive isotopes to date rocks and fossils?
The basic idea is to compare the abundance of a naturally occurring radioactive isotope within a material to the abundance of its decay products; it is known how fast the radioactive isotope decays.
What is a researcher who uses carbon dating on ancient item?
Archaeologists routinely use carbon dating on ancient artifacts in order to find an approximate date for them. Conservationist and Preservationists will also use carbon dating to find the date of objects they are working on.
Why radioactive decay to date fossils and artifacts?
Radioactive decay is used to date fossils and artifacts because certain radioactive isotopes have predictable rates of decay over time. By measuring the amount of remaining radioactive isotopes in a fossil or artifact, scientists can estimate how long it has been since the material was formed. This method is known as radiometric dating and provides a way to determine the age of objects that are thousands to billions of years old.
How far back can artifacts date back to?
Artifacts can date back thousands to millions of years, depending on the material and preservation conditions. The oldest known artifacts, such as stone tools and cave paintings, date back to millions of years ago.
