Carbon dating to

The SUERC Radiocarbon Laboratory is involved in archaeological, forensic and environmental research, additionally using stable isotopes (13C and 15N) for dietary reconstruction.As well as undertaking its own in-house and collaborative research, the SUERC Radiocarbon Laboratory also provides a radiocarbon dating service to national and international museums, universities and archaeology units.In other words, the further you go back, the more you have to shrink the radiocarbon dates to make them fit the facts.

Clearly they can’t be any more recent than the Dissolution of 1538.

The SUERC results showed a 95% probability that the bone samples dated from around AD1430-1460, and over in Oxford the results both came out at around AD1412-1449, again with a 95% confidence. Radiocarbon dating of marine organisms can be out by up to several hundred years, and this effect can occur to a lesser degree in terrestrial life where sea-food forms part of the diet.

The mass spectrometry of the Greyfriars bone samples reveals that the individual in question had a high-protein diet including a significant proportion of seafood.

We’ve seen that it would have been the same as in the atmosphere at the time the specimen died. Do scientists assume that it was the same as it is now? It is well known that the industrial revolution, with its burning of huge masses of coal, etc.

has upset the natural carbon balance by releasing huge quantities of C ratio was like before the industrial revolution, and all radiocarbon dating is made with this in mind.
