This "wiggle-matching" technique can lead to more precise dating than is possible with individual radiocarbon dates. [89] Wiggle-matching can be used in places where there is a plateau on the calibration curve, [note 12] and hence can provide a much more accurate date than the intercept or probability methods are able to produce. [91]

The finding kicked off a huge salvage project to record and date the fossils, which turned out to be roughly 8.7 million years old. Los Angeles used to be under water.

This makes carbon-14 an ideal dating method to date the age of bones or the remains of an organism. The carbon-14 dating limit lies around 58,000 to 62,000 years. [32] The rate of creation of carbon-14 appears to be roughly constant, as cross-checks of carbon-14 dating with other dating methods show it gives consistent results.
The calculation of radiocarbon dates determines the age of an object containing organic material by using the properties of radiocarbon (also known as carbon-14), a radioactive isotope of carbon. Radiocarbon dating methods produce data based on the ratios of different carbon isotopes in a sample that must then be further manipulated in order to ...
