# Radiometric Dating **How it works:** Radiometric dating measures the decay of radioactive isotopes in rocks and minerals. Radioactive elements decay at predictable, constant rates (called half-lives), transforming into different elements over time. By measuring the ratio of parent isotopes to daughter products, scientists can calculate how long the decay has been occurring—revealing the age of the material. ## Common Misconception **"Carbon-14 dating is used to date dinosaur fossils and ancient rocks"** This is incorrect. Carbon-14 has a half-life of only about 5,730 years, making it useful for dating organic materials up to ~50,000-60,000 years old. Dinosaur fossils (65+ million years old) and ancient rocks require different isotopes with much longer half-lives, such as: - Uranium-238 (4.5 billion years) - Potassium-40 (1.3 billion years) - Rubidium-87 (49 billion years) Each radiometric method has an appropriate age range and material type for accurate dating.
