Radiocarbon dating is useful for dating dinosaur fossils enfp dating an entp
Since the moon and the Earth probably formed at the same time, this supports the current idea of the Earth's age.You can learn more about fossils, dinosaurs, radiometric dating and related topics by reading through the links below.This information has also helped determine the age of the Earth itself.While the oldest known rocks on Earth are about 3.5 billion years old, researchers have found zircon crystals that are 4.3 billion years old [source: USGS].But dinosaur fossils have been discovered with detectable radiocarbon, which proves they died only thousands of years ago, not millions of years ago.Evolutionists try rescuing devices like saying the samples were contaminated.

Some of the isotopes used for this purpose are uranium-238, uranium-235 and potassium-40, each of which has a half-life of more than a million years.
By using radiometric dating to determine the age of igneous brackets, researchers can accurately determine the age of the sedimentary layers between them.
Using the basic ideas of bracketing and radiometric dating, researchers have determined the age of rock layers all over the world.
This is an extraordinary discovery because Carbon-14 has a half-life of only 5,730 years.
As a result, any Carbon-14 in a sample should decay to undetectable levels well under 100,000 years.
Fossils can't form in the igneous rock that usually does contain the isotopes.
