In 1949, American chemist Willard Libby, who worked on the development of the atomic bomb, published the first set of radiocarbon dates.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.Radiocarbon is then taken in by plants through photosynthesis, and these plants in turn are consumed by all the organisms on the planet.

Since plankton is the foundation of the marine food chain, Carbon-14 is spread throughout aquatic life.Rodents, for example, can create havoc in a site by moving items from one context to another.Natural disasters like floods can sweep away top layers of sites to other locations.The extra neutrons in Carbon-14’s case make it radioactive (thus the term, radiocarbon).



If the carbon14 used to date an organism, let's say an elephant is derived mainly from the plants ingested, and the elephant is dated by comparing it's ratio of carbon atoms to another elephant's ratio of carbon atoms, how do you account for the amount of plants the elephant actually ate? For illustrative purposes, let's.… continue reading »

Nov 20, 2012. Though still heavily used, relative dating is now augmented by several modern dating techniques. Radiocarbon dating involves determining the age of an ancient fossil or specimen by measuring its carbon-14 content. Carbon-14, or radiocarbon, is a naturally occurring radioactive isotope that forms when.… continue reading »
