Best suited to the carbon 14 dating technique
Other techniques include analyzing amino acids and measuring changes in an object's magnetic field.
Scientists have also made improvements to the standard radiometric measurements.
Also, many fossils are contaminated with carbon from the environment during collection or preservation procedures.
This is what archaeologists use to determine the age of human-made artifacts. 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.
This restriction extends to animals that consume seafood in their diet.
As stated previously, carbon dating cannot be used on artifacts over about 50,000 years old.

Radiometric dating isn't the only method of determining the age of rocks.
