Carbon-14.
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.
Carbon 14 is the isotope that is used for carbon dating.
The radioactive isotope 14C.
The carbon isotope used in radioactive dating of artifacts is carbon-14. It is produced in the atmosphere by cosmic ray bombardment and is absorbed by living organisms. When an organism dies, the amount of carbon-14 decreases over time through radioactive decay, which can be used to determine the age of the artifact.
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.
Carbon-14 is the isotope most commonly used in radioactive dating of organic materials like bones and charcoal.
Both radioactive isotopes and radioactive dating rely on the process of radioactive decay. Radioactive isotopes decay at a known rate, allowing scientists to measure the passage of time based on the amount of decay that has occurred. Radioactive dating uses this decay process to determine the age of rocks and fossils.

Carbon 14... i just did that same question on castle learning haha :)
Carbon-12 is the most common isotope of carbon, with 6 protons and 6 neutrons. Carbon-14 is a radioactive isotope of carbon with 6 protons and 8 neutrons, commonly used in radiocarbon dating to determine the age of organic materials.
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'
In radiometric dating, the amount of a certain radioactive isotope in an object is compared with a reference amount. This ratio can then be used to calculate how long this isotope has been decaying in the object since its formation. For example, if you find that the amount of radioactive isotope left is one half of the reference amount, then the amount of time since the formation of the object would be equal to that radioactive isotope's half-life.
