Topic: Carbon-14, Radiometric Dating and Index Fossils - Home EN

Carbon dating is used to determine the age of biological artifacts up to 50,000 years old. This technique is widely used on recent artifacts, but educators and students alike should note that this technique will not work on older fossils (like those of the dinosaurs alleged to be millions of years old).

1 Re: Can you use carbon dating on fossils

Radiometric dating - Evolution Bracketing the fossils Fossils are generally found in sedimentary rock — not igneous rock. Sedimentary rocks can be dated using radioactive carbon, but because carbon decays relatively quickly, this only works for rocks younger than about 50 thousand years.

Hi. Author well done!

3 Re: Can you use carbon dating on fossils

BioMath: Carbon Dating - The Biology Project Carbon dating is based upon the decay of 14 C, a radioactive isotope of carbon with a relatively long half-life (5700 years). While 12 C is the most abundant carbon isotope, there is a close to constant ratio of 12 C to 14 C in the environment, and hence in the molecules, cells, and tissues of living organisms.

Dating dinosaurs and other fossils - Australian Museum Fossils themselves, and the sedimentary rocks they are found in, are very difficult to date directly. Instead, other methods are used to work out a fossil’s age. These include radiometric dating of volcanic layers above or below the fossils or by comparisons to similar rocks and fossils of known.

5 Re: Can you use carbon dating on fossils

How accurate are Carbon-14 and other radioactive dating. People who ask about carbon-14 (14 C) dating usually want to know about the radiometric[1] dating methods that are claimed to give millions and billions of years—carbon dating can only give thousands of years. People wonder how millions of years could be squeezed into the biblical account of.

6 Re: Can you use carbon dating on fossils

Dating Fossils – How Are Fossils Dated? - FossilEra.com Carbon-14, the radioactive isotope of carbon used in carbon dating has a half-life of 5730 years, so it decays too fast. It can only be used to date fossils younger than about 75,000 years. Potassium-40 on the other hand has a half like of 1.25 billion years and is common in rocks and minerals.

Dating a Fossil - Carbon Dating | HowStuffWorks Dating a Fossil - Carbon dating compares the ratio of carbon-12 to carbon-14 atoms in an organism. Learn about carbon dating and find out what the carbon-14 half-life is.

Carbon Dating - Don Lindsay Archive If you hear of a carbon dating up in the millions of years, you're hearing a confused report. We can't date oil paints, because their oil is 'old' carbon from petroleum. We can't date fossils, for three reasons.

Showing Their Age | History | Smithsonian Showing Their Age Dating the Fossils and Artifacts that Mark the Great Human Migration. The organic remains were too old for carbon-14 dating, so the team turned to another method.

CARBON DATING OF FOSSILS - dinosaurc14ages.com Radiocarbon (RC) or (C-14) dating of linen, cotton, bones, fossils, wood, sea shells, seeds, coal, diamond (anything with carbon) is one of the most common and well understood of the various scientific dating methods.
