For those of you interested in radiocarbon dating, I’d like to draw your attention to an article that reports a significant milestone in the calibration curves for C-14 dating. The international working group INTCAL, which compiles the accepted calibration curve, has now extended the calibration curve from 26,000 years to 50,000 years, a major accomplishment. The significance of this announcement is that many discoveries in that time frame can now be dated with more confidence, such as early cave art.
From a personal perspective, I’m proud to say that the team leader, Paula Reimer, is married to a good friend of mine from my home town. I haven’t seen him for four decades but I always enjoy hearing from him and about their work in radiocarbon dating.
