For the Fern Cave samples, the lower circle, calibrated at AD 1020-1290 (+/- 2 o Range) is distinctly older than both the upper circle, at AD 1490-1955, and the crescent, at AD 1440-1670. Radiocarbon determinations on the upper circle and crescent are not signifcantly different from one another; they may have been painted contemporaneously. Both features date from several centuries after the AD 1054 supernova. There were no discernible differences in terms of colour or other visual features between the thre figures studied here. The C contents of the three figures of the panted panel demonstrate conclusively that it does not represent the AD 1054 supernova.
