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 note that at the instant the swimmer touches the edge of the pool our wristwatch reads and 53 seconds.
How long has the competitor taken to swim the 1,500 metre race?
How old are the bones found under the Greyfriars church?
During the race you have to watch the swimmer and count how many laps he has swum so you know that he has done 1,500 metres.
But if they are earlier than 1485, then they can’t be Richard’s remains.
Radiocarbon dating is a commonly used technique which relies on the fact that, although 99% of carbon atoms have six protons and six neutrons (carbon-12), about 1% have an extra neutron (carbon-13) and about one atom in a trillion has two extra neutrons (carbon-14).
This does not, of course, prove that the bones are those of Richard III.
What it does is remove one possibility which could have proved that these are not Richard’s remains.
