As an example Pinnacle Point's caves, in the southern coast of South Africa, provided evidence that marine resources (shellfish) have been regularly exploited by humans as of 170,000 years ago.On the other hand, remains as recent as a hundred years old can also be the target of archaeological dating methods.
With a thorough understanding of this dating method, it is my opinion that its ingenious fundamentals can be appreciated, yet greatly overshadowed by its limitations.
Radiocarbon Every day cosmic rays bombard our atmosphere.
It was the case of an 18th-century sloop whose excavation was led in South Carolina (United States) in 1992.
Thus, from the oldest to the youngest, all archaeological sites are likely to be dated by an appropriate method.
As is common fact, plants photosynthesize and consume CO2, fixing its carbon.
Since a small fraction of CO2 contains C14, some of carbon fixed within the plant is that of C14.
In this relative dating method, Latin terms ante quem and post quem are usually used to indicate both the oldest and the most recent possible moments when an event occurred or an artifact was left in a stratum.
But this method is also useful in many other disciplines.
These cosmic rays release free neutrons which zip around our nitrogen rich atmosphere at high velocities.
