however, radioisotope dating may not work so well in the future. neither the pre-existing egyptian chronology nor the new radiocarbon dating method could be assumed to be accurate, but a third possibility was that the 14c/12c ratio had changed over time.-14 dating can tell you how old this dinosaur skull is. dating (also referred to as carbon dating or carbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon (14c), a radioactive isotope of carbon. using this information and the given half-life of carbon 14, explain why this method of dating is not used for dinosaur remains. more broadly, the success of radiocarbon dating stimulated interest in analytical and statistical approaches to archaeological data.

[26][28] equipped with the results of carbon-dating the tree rings, it became possible to construct calibration curves designed to correct the errors caused by the variation over time in the 14c/12c ratio. order to use carbon $ for dating, scientists measure the ratio. other useful radioisotopes for radioactive dating include uranium -235 (half-life = 704 million years), uranium -238 (half-life = 4. 2016, the development of radiocarbon dating was recognized as a national historic chemical landmark for its contributions to chemistry and society by the american chemical society. before the advent of radiocarbon dating, the fossilized trees had been dated by correlating sequences of annually deposited layers of sediment at two creeks with sequences in scandinavia. using this information and the given half-life of carbon 14, explain why this method of dating is not used for dinosaur remains.
