The resulting radiocarbon combines with atmospheric oxygen to form radioactive carbon dioxide, which is incorporated into plants by photosynthesis; animals then acquire in a sample from a dead plant or animal such as a piece of wood or a fragment of bone provides information that can be used to calculate when the animal or plant died.The older a sample is, the less (the period of time after which half of a given sample will have decayed) is about 5,730 years, the oldest dates that can be reliably measured by this process date to around 50,000 years ago, although special preparation methods occasionally permit accurate analysis of older samples.
Can carbon dating work on stone
Additional complications come from the burning of fossil fuels such as coal and oil, and from the above-ground nuclear tests done in the 1950s and 1960s.
Carbon dating is used to determine the age of biological artifacts up to 50,000 years old.
Determining the age of a stone carving relies more on the context than the stone itself.-Is the carving done in a known style, or does it depict a known image?
-Was the carving found alongside any organic materials that can be carbon dated?
This restriction extends to animals that consume seafood in their diet.
