Radiocarbon dating pictures

There was a revolution in our ability to answer that important question starting three decades ago (1977).

The major advancement that laid the groundwork for the later dating revolution was the development of accelerator mass spectrometry (AMS).

That innovation led to a drastic reduction in the amount of carbon necessary for a radiocarbon date - from a few grams to less than 1 mg of carbon.

This reduction in sample size opened the way for even the small amounts of organic matter in rock paintings to be dated starting a decade later in 1987.

Scholars use the science of dendrochronology, which matches those annular rings to known carbon fluctuations.

Radiocarbon dating was invented in the late 1940's, and within a few decades, it was discovered that while the dates retrieved from the method have a sound, repeatable progression, they are not a one-to-one match with calendar years.

Most importantly, researchers discovered that radiocarbon dates are affected by the amount of carbon in the atmosphere, which has fluctuated greatly in the past for both natural and human-caused reasons (such as the invention of iron smelting, the Industrial Revolution, and the invention of the combustion engine).

Tree rings, which keep a record of the amount of carbon in the atmosphere when they are created, are used to calibrate or fine-tune radiocarbon dates to their calendar dates.
