Carbon dating symbol
Carbon's incredible ability to bond with many other elements is a major reason that it is crucial to almost all life. The element was known to prehistoric humans in the form of charcoal.
Carbon as coal is still a major source of fuel worldwide, providing about 30 percent of energy worldwide, according to the World Coal Association.
Their findings, published in the leading archaeology journal , support the idea that the symbols represent a script likely to be a naming system communicating the identities of Picts and that this was developed in the same era as other writing systems across Europe like the ogham script of early Ireland and the runic system developed in Scandinavia.
“Establishing an outline chronology through a combination of direct dating, modelling and examining associated dates from archaeological excavation is helping us rewrite the history of these symbolic traditions of Northern Europe and to understand more clearly the context of their development and use,” said Gordon Noble, Head of Archaeology at the University of Aberdeen, who also led the archaeological excavations.
Carbon has two electron shells, with the first holding two electrons and the second holding four out of a possible eight spaces.
Dr Hamilton said: “Bayesian modelling has revolutionised the world of radiocarbon dating, helping us to develop more refined chronological frameworks than was previously possible.
