The carbon-14 dating method, however, cannot be used on dinosaur bones. Due to the fact that carbon-14 has a half-life of just 5,730 years, carbon-14 dating can only be used on samples that are less than 50,000 years old. In order for scientists to calculate the ages of these fossils, they need an isotope that has an extremely lengthy half-life.
