Radiocarbon dating hominids

The age of the carbon in the rock is different from that of the carbon in the air and makes carbon dating data for those organisms inaccurate under the assumptions normally used for carbon dating.This restriction extends to animals that consume seafood in their diet.However, we do feel that there are a number of physical attributes of the specimen which might have tipped you off to it’s modern origin: It is with feelings tinged with melancholy that we must deny your request to have the specimen carbon dated.This is partially due to the heavy load our lab must bear in it’s normal operation, and partly due to carbon dating’s notorious inaccuracy in fossils of recent geologic record.As stated previously, carbon dating cannot be used on artifacts over about 50,000 years old.These artifacts have gone through many carbon-14 half-lives, and the amount of carbon-14 remaining in them is miniscule and very difficult to detect.

Although the half-life of some of them are more consistent with the evolutionary worldview of millions to billions of years, the assumptions used in radiometric dating put the results of all radiometric dating methods in doubt. Although the half-life of carbon-14 makes it unreliable for dating fossils over about 50,000 years old, there are other isotopes scientists use to date older artifacts.Nuclear tests, nuclear reactors and the use of nuclear weapons have also changed the composition of radioisotopes in the air over the last few decades.This human nuclear activity will make precise dating of fossils from our lifetime very difficult due to contamination of the normal radioisotope composition of the earth with addition artificially produced radioactive atoms.Carbon dating cannot be used on most fossils, not only because they are almost always allegedly too old, but also because they rarely contain the original carbon of the organism that has been fossilized.Also, many fossils are contaminated with carbon from the environment during collection or preservation procedures.
