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.

Which isotope is useful for dating wood and charcoal that is less than about 75000 years old?
carbon- 14
Can radiocarbon dating be used to determine the age of dinosaur fossils?
no , b/c the fossils are older than 50,000 years old & contain too little carbon-14 to be measurable
Why are half lives useful to an archeologist?
The half-life of radioactive material is useful for radioactive dating. For example, All organisms on earth have a given concentration of carbon-14. Since carbon-14 has a half life of 5700 years, scientists can fairly estimate the lifespan of an organism based on its carbon-14 content. This is done by measuring the amount of carbon-14 left from its (previously calculated in a lab) initial amount. If there is exactly a quarter of the initial amount of carbon-14 left in an organism, then it is safe to assume that the organism is 11400 years old. This is why the half-life of a radioactive material is useful for radioactive dating.
Are carbon dating and radiocarbon dating the same?
Yes, carbon dating and radiocarbon dating refer to the same test, which is the analysis of the carbon 14 isotope.
How does carbon dating work ma?
This method of dating is based on the radioactive decay of carbon-14.
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
