* Three Related Lines of Evidence Shoring Up the Young Earth Interpretation: The interaction between dinosaur soft tissue, unracemized left-handed amino acids, and Carbon 14 must all be explained to understand the true age of the geologic column.(1) Significant amounts of short-lived 14c, in quantities far above the least count (margin of error) of our state-of-the-art equipment, is measured in diamonds, dinosaur fossils, marble, giant extinct aquatic lizard, natural gas, coal (and see this paper at Science Direct), and reportedly in oil.The other two isotopes in comparison are more common than carbon-14 in the atmosphere but increase with the burning of fossil fuels making them less reliable for study (2); carbon-14 also increases, but its relative rarity means its increase is negligible. After this point, other Absolute Dating methods may be used.Today, the radiocarbon-14 dating method is used extensively in environmental sciences and in human sciences such as archaeology and anthropology.Radiocarbon dating may only be used on organic materials.Typically (6): The above list is not exhaustive; most organic material is suitable so long as it is of sufficient age and has not mineralised - dinosaur bones are out as they no longer have any carbon left.In any case, creationist scientists are now boldly going where evolutionists have feared to tread.
The resulting data, in the form of a calibration curve, is now used to convert a given measurement of radiocarbon in a sample into an estimate of the sample's calendar age.As ICR scientist Brian Thomas points out, "Because radiocarbon decays relatively quickly, fossils that are even 100,000 years old should have virtually no radiocarbon left in them.But they do." Using the services of five different commercial and academic laboratories, the research team tested seven dinosaur bones and detected carbon-14 in them all.The older a sample is, the less (the period of time after which half of a given sample will have decayed) is about 5,730 years, the oldest dates that can be reliably measured by this process date to around 50,000 years ago, although special preparation methods occasionally permit accurate analysis of older samples.The idea behind radiocarbon dating is straightforward, but years of work were required to develop the technique to the point where accurate dates could be obtained.
