Radiocarbon dating.
Radiocarbon dating was developed by Willard Libby in 1949.
Radiocarbon dating is not used for dinosaur bones because dinosaurs lived millions of years ago, and radiocarbon dating is only effective for dating objects up to around 50,000 years old. Dinosaurs are too old for this method to accurately determine their age.
Radiocarbon is another name for carbon 14, which is a weakly radioactive isotope of the element carbon.
Carbon 14 is the isotope of carbon measured in radiocarbon dating.
Carbon 14 is the isotope of carbon measured in radiocarbon dating.
Scientists do not always use a 120 year range when radiocarbon dating an artifact. Calibrated radiocarbon ages are often expressed as below 2670 (± 120) where 2670 refers to the age of the sample and the 120 after the symbol indicates that this age may be older or younger than the given age by 120 years. This varying level of precision comes in because the calibration curves used to turn radiocarbon ages into calender dates are not perfectly smooth, and it may be that for some preiods a radiocarbon age may be equivilent to serveal calender dates. This margin of error varies depending on the age of the sample and for some periods will be significantly less (maybe only a decade or so) and for some periods will be significantly more (for example during the early Iron age, 800 - 400BC where radiocarbon dating can offer no greater precision than several hundered years.
