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 Carbon Cycle. Radiocarbon dating (usually referred to simply as carbon dating) is a radiometric dating method. It uses the naturally occurring radioisotope carbon (14 C) to estimate the age of carbon-bearing materials up to about 58, to 62, years [HOST] has two stable, nonradioactive isotopes: carbon (12 C) and carbon (13 C).
Nearly caves have now been discovered in France and Spain that contain art from prehistoric times. Initially, the age of the paintings had been a contentious issue, since methods like radiocarbon dating can produce misleading results if contaminated by samples of older or newer material, and caves and rocky overhangs (where parietal art is found) are typically littered with debris from.
