Determining the age of dinosaur bones is not possible alone It is not limited to examining fossils. The scientific methods used are both complex and impressive.

So what kind of method do they use to determine their age? “good looking” Can they determine?

Radiometric dating is now the most commonly used method to determine the age of fossils.

This method is based on the properties of isotopes. isotopes, number of protons of the same element the same but different number of neutrons are variants.

Atoms can contain equal numbers of protons and neutrons. However, when the number of neutrons is more or less greater, the atom becomes unstable and sheds its particles until it reaches a more stable state.

Period of time, Works like a radioactive clock and unstable isotopes change to stable isotopes over time.

The half-life of an isotope refers to the time it takes for half of the parent atoms in the sample to convert to daughter atoms.

Scientists will measure the number of parent and daughter atoms mass spectrometer It uses a device called . The greater the number of parent isotopes and the fewer the number of daughter isotopes, the younger the sample.

Isotopes with short half-lives are not suitable for dating dinosaur bones. Because dinosaur bones are millions of years old isotopes with longer half-lives has been used.

Carbon-14 dating is the best-known radiometric dating method used by archaeologists to determine the age of human-made artifacts.

However The half-life of carbon-14 is only 5,730 years, this makes it ineffective for samples older than 50,000 years. Dinosaur bones are millions of years old, so isotopes with longer half-lives are needed.
