Carbon 14 is useful for dating organic remains less than 60-70,000 years old. It is not useful for fossils as the vast majority are much older than that.

Can radiocarbon dating be used to determine the age of dinosaur fossils?
No, radiocarbon dating cannot be used to determine the age of dinosaur fossils because the half-life of carbon-14 is too short for dating objects that are millions of years old. Instead, other dating methods like uranium-lead dating or potassium-argon dating are used for dating dinosaur fossils.
What can carbon dating be used to date?
Carbon dating can be used to date organic materials, such as wood, bones, shells, and charcoal. It is particularly useful for determining the age of archaeological artifacts and fossils that are up to about 50,000 years old.
Could scientists use carbon dating to determine the age of hominids?
Yes, scientists can use carbon dating to determine the age of hominid fossils. Carbon dating relies on measuring the amount of carbon-14 present in a sample to estimate its age. However, carbon dating is typically used on organic materials up to around 50,000 years old, so other dating methods may be necessary for older hominid fossils.
Since radioactive isotopes decay at different rates how is radiocarbon dating of any value in determining how old a fossil is?
Radiocarbon dating is useful for determining the age of organic materials such as fossils because it measures the decay of carbon-14 isotopes. Carbon-14 has a half-life of about 5,730 years, making it suitable for dating organic remains up to around 50,000 years old. By comparing the ratio of carbon-14 to stable carbon isotopes in a sample, scientists can calculate its age.
Which isotope is useful for dating wood and charcoal that is less than about 75000 years old?
Carbon-14 is the isotope commonly used for dating wood and charcoal less than about 75,000 years old. This isotope is useful because plants take in carbon-14 while they are alive, and it decays at a known rate after the plant dies, allowing for accurate dating.
Carbon-14 is useful for dating fossils that are what?
Old
What radioactive carbon isotope is used in dating fossils?
Carbon-14.
How do scientists use Carbon-14 to date fossils?
Carbon-14 is in all living things and decays after it dies. It has a long half life (the time it takes for half a sample to decay into another element) and gives a good estimate as to how old something is. Carbon dating is only effective up to an approximate age of 70,000 years, and is only useful in dating organic matter. Since the vast majority of fossils are much older than this, carbon dating is not particularly useful in dating fossils, but is of great use in archaeology.
What is the function of radioisotopes C-14?
Used in carbon dating that is to find the age of fossils.
Which isotopes is most useful for dating wood and charcoal?
carbon-14
What are two ways to date fossils?
Radio-carbon dating is one, carbon 14 changes to carbon 13 over time, scientists measure how much carbon 14 is left in a fossil to determine how old it is.
Why is the isotope carbon-14 so helpful in dating rocks?
It is not useful in dating rocks. Only organic substances in terrestrial conditions. No carbon in rocks.
Which geological epoch is carbon 14 is most useful for dating organic remains?
precambrian
What is C-14 used for?
it is used as an isotope and it can be used for good or super villain purposes.
Why is carbon dating not useful for dating metal artifact?
Metal artifacts rarely contain residues of organic products. Carbon-14 dating is adequate only for artifacts containing organic materials.
What is radioisotope carbon dating?
Carbon 14 is the isotope that is used for carbon dating.
Which isotope is useful for dating wood and charcoal that is less than 75000 years old?
carbon- 14
