How Do Scientists Determine the Age of Dinosaur Bones? | HowStuffWorks
Radiocarbon dating is a key tool archaeologists use to determine the age of plants and objects made with organic material. But new research shows that commonly accepted radiocarbon dating standards can miss the mark—calling into question historical timelines. Archaeologist Sturt Manning and colleagues have revealed variations in the radiocarbon cycle at certain periods of time, affecting frequently cited standards used in archaeological and historical research relevant to the southern Levant region, which includes Israel, southern Jordan and Egypt. These variations, or offsets, of up to 20 years in the calibration of precise radiocarbon dating could be related to climatic conditions. Pre-modern radiocarbon chronologies rely on standardized Northern and Southern Hemisphere calibration curves to obtain calendar dates from organic material.

Thanks to Fossil Fuels, Carbon Dating Is in Jeopardy. One Scientist May Have an Easy Fix
Radiometric dating calculates an age in years for geologic materials by measuring the presence of a short-life radioactive element, e. The term applies to all methods of age determination based on nuclear decay of naturally occurring radioactive isotopes. Bates and Jackson To determine the ages in years of Earth materials and the timing of geologic events such as exhumation and subduction, geologists utilize the process of radiometric decay. Geologists use these dates to further define the boundaries of the geologic periods shown on the geologic time scale. Radiometric decay occurs when the nucleus of a radioactive atom spontaneously transforms into an atomic nucleus of a different, more stable isotope.
But our relentless use of fossil fuels has pumped a type of carbon into the atmosphere that is starting to confuse the dating technique. By , scientists warn, new fabrics could have the same radiocarbon date as items 1, years old! According to new research published in the journal Proceedings of the National Academy of Sciences , growing emissions from the burning of fossil fuels are threatening the effectiveness of the radiocarbon dating method. The decay of carbon isotopes within living organisms can be used to date organic materials , such as charcoal, or shell and bone, and some inorganic materials, excluding metals. Radiocarbon dating was developed in the late s by Willard Libby, as a method to measure radioactivity.
