Question: Why do we use carbon dating for dinosaur bones?

To determine the age of a dinosaur fossil, carbon dating can never be used. Carbon-14 only works for fossils less than 75,000 years old. Carbon-14 has a half life of 5730 years and this radioisotope eventually decays into Nitrogen-14.

Why is carbon-14 used to date dinosaur bones?

But carbon-14 dating wont work on dinosaur bones. The half-life of carbon-14 is only 5,730 years, so carbon-14 dating is only effective on samples that are less than 50,000 years old. To determine the ages of these specimens, scientists need an isotope with a very long half-life.
