why is carbon dating not useful for dinosaurs

How can carbon dating determine the age of a dinosaur fossil?

To determine the age of a dinosaur fossil, carbon dating can never be used. Carbon-14 only works for fossils less than 75,000 years old. By the time a dinosaur fossil was found, any carbon-14 the organism would have taken up and incorporated into its tissues during its life, would have decayed too much to be useful as a tool...

Why is carbon dating not accurate?

Since carbon dating measures the amount of carbon still in a fossil, then the date given is not accurate. Carbon dating makes an animal living 4 thousand years ago (when there was less atmospheric carbon) appear to have lived thousands of years before it actually did. What was the original amount of Carbon in the atmosphere?

Can C14 dating be used to date dinosaurs?

With a half-life of about 5500 years, C14 dating thus maxes out at around 55,000 years, which is plenty too recent for effectively dating dinosaur bones. Also C14 dating only works on organic materials.

How does carbon-14 dating work?

Carbon-14 dating uses a radioactive carbon isotope known as a radiocarbon. Radiocarbons, nicknamed carbon-14s, has eight neutrons and six protons in their atomic nucleus. In the 1940s, Willard Libby, a chemist at the University of Chicago, created the process of carbon-14 dating.

What is the difference between carbon 14 dating and dinosaur dating?

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. Dinosaur bones, on the other hand, are millions of years old -- some fossils are billions of years old.

How do scientists determine the age of a fossil?

Today’s knowledge of fossil ages comes primarily from radiometric dating, also known as radioactive dating. Radiometric dating relies on the properties of isotopes. These are chemical elements, like carbon or uranium, that are identical except for one key feature — the number of neutrons in their nucleus.

What is the difference between carbon dating and fossilization?

The first being, for something to be a fossil, it usually is not longer something containing organic carbon. The fossilization process replaces the existing composition with minerals. Non-organic material. Carbon dating cannot be used on inorganic minerals. The second being, carbon dating is only useful up to about 50 thousand years ago MAX.

How can you tell how old a dinosaur bone is?

The most widely known form of radiometric dating is carbon-14 dating. This is what archaeologists use to determine the age of human-made artifacts. But carbon-14 dating wont work on dinosaur bones. 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.
