Paul is super awesome, so I'm going to take him at his word.
In fact, Paul already knows that coelophysis lived around 200 million years ago, while iguanodon lived around 150 million years ago.This process begins as soon as a living thing dies and is unable to produce more carbon-14.Plants produce carbon-14 through photosynthesis, while animals and people ingest carbon-14 by eating plants. Scientists determine the ages of once-living things by measuring the amount of carbon-14 in the material.Radioactive dating uses the decay rates of radioactive substances to measure absolute ages of rocks, minerals and carbon-based substances, according to How Stuff Works.Scientists know how quickly radioactive isotopes decay into other elements over thousands, millions and even billions of years.Let's find out more about these geological dating methods in order to understand how Paul the Paleontologist can be so sure about the age of his dinosaur fossils.
The first method that scientists use to determine the age of rocks is relative dating.The ratio of the original isotope and its decay product determines how many half-lives have occurred since the sample formed.A half-life measures the time it takes for one half of a radio isotope's atoms to break down into another element.Plus, get practice tests, quizzes, and personalized coaching to help you succeed.Free 5-day trial Learn how scientists determine the ages of rocks and fossils.The key in relative dating is to find an ordered sequence.
