Fortunately, Willard Libby, a scientist who would later win the 1960 Nobel Prize in Chemistry, developed the process known as radiocarbon dating in the late 1940s. In a nutshell, it works like this: After an organism dies, it stops absorbing carbon-14, so the radioactive isotope starts to decay and is not replenished.

The data can be a little off particularly in younger artifacts, and anything older than about 50,000 years is pretty much too old to be tested because at that point the majority of the C-14 has decayed to practically undetectable levels.His radiocarbon dating technique is the most important development in absolute dating in archaeology and remains the main tool for dating the past 50,000 years.How It Works: Carbon has 3 isotopic forms: Carbon-12, Carbon-13, and Carbon-14.But now archaeologists studying, say, the development of agriculture across the continents are able to determine how different societies stacked up against one another throughout the millennia.When it comes to dating archaeological samples, several timescale problems arise.Prior to the development of radiocarbon dating, it was difficult to tell when an archaeological artifact came from.

Unless something was obviously attributable to a specific year -- say a dated coin or known piece of artwork -- then whoever discovered it had to do quite a bit of guesstimating to get a proper age for the item.Although relative dating can work well in certain areas, several problems arise.Rodents, for example, can create havoc in a site by moving items from one context to another.Despite these limitations, radiocarbon dating will often get you a decent ballpark figure.While other methods of dating objects exist, radiocarbon dating has remained vital for most archaeologists.There's also still usually a wide window of time that an object can fall into.
