The idea behind radiocarbon dating is straightforward, but years of work were required to develop the technique to the point where accurate dates could be obtained.

The state of Arkansas was apparently originally known as the Territory of Arkansaw [sic].

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.

There is three main categories that the artifacts fall under; pottery, bones and stone artifacts. An archeologist then uses artifacts that have been found to make a reconstruction the way people lived during that time period.

Archaeologists use two types of dating, relative and absolute.
