Comments
A measures radiocarbon age is not reported for infinite dates since corrections may imply a greater level of confidence than is appropriate The 14C activity was extremely low and almost identical to the background signal. In such cases, indeterminate errors associated with the background add non-measurable uncertainty to the result, Always, the result should be considered along with other lines of evidence. The most conservative interpretation of age in infinite (i.e. greater than). 15N/14N +7.9
