One of the most important dating tools used in archaeology may sometimes give misleading data, new study shows - and it could change whole historical timelines as a result. The discrepancy is due to significant fluctuations in the amount of carbon in the atmosphere, and it could force scientists to rethink how they use ancient organic remains to measure the passing of time. A comparison of radiocarbon ages across the Northern Hemisphere suggests we might have been a little too hasty in assuming how the isotope - also known as radiocarbon - diffuses, potentially shaking up controversial conversations on the timing of events in history. By measuring the amount of carbon in the annual growth rings of trees grown in southern Jordan, researchers have found some dating calculations on events in the Middle East — or, more accurately, the Levant — could be out by nearly 20 years.

Archaeologists got one thing wrong about North American indigenous history

Radiocarbon dating also referred to as carbon dating or carbon dating is a method for determining the age of an object containing organic material by using the properties of radiocarbon , a radioactive isotope of carbon. The method was developed in the late s at the University of Chicago by Willard Libby , who received the Nobel Prize in Chemistry for his work in It is based on the fact that radiocarbon 14 C is constantly being created in the atmosphere by the interaction of cosmic rays with atmospheric nitrogen. The resulting 14 C combines with atmospheric oxygen to form radioactive carbon dioxide , which is incorporated into plants by photosynthesis ; animals then acquire 14 C by eating the plants.
