UP NEXT. Pearson and her team used the patterns of carbon-14 captured in the Gordion tree rings to anchor the floating chronology to similar patterns from other calendar-dated tree ring sequences. Even in a conservative scenario, however, David Horvath of the University of Arizona, the paper’s lead author, said the eruption would have been only a million years ago. "I think to do good science you have to investigate everything and keep an open mind until sufficient data comes together," Pearson said. But since the completion of the university's upgraded Bryant Bannister Tree Ring Building in 2013, the curation team, led by Peter Brewer, has been relocating, organizing and preserving samples for future research.
