But new research shows that commonly accepted radiocarbon dating standards ...

Radiocarbon dating of a fossilized leg bone from a Jamaican monkey called Xenothrix mcgregori suggests it may be the one of the most recent primate species anywhere in the world to become extinct, ...

"We wanted to tackle this time period in hopes we could use this to shed new light on the Thera debate." Hodgins said, "This research is about Thera, but really, the implications of it are profound for anyone that uses radiocarbon dating throughout the world for this time span.

There's a kind of revolution in the radiocarbon community to revise the calibration curve using these more precise measurements." Other research teams are also finding discrepancies between their radiocarbon measurements using annual tree rings and the current radiocarbon calibration curve, he said.

Co-author Gregory Hodgins, director of the UA AMS lab, said, "Charlotte is redoing the calibration curve at an annual scale.

By using radiocarbon measurements from the annual rings of trees that lived at the time of the eruption, the UA-led team dates the eruption to someplace between 16, a time period which overlaps with the 1570-1500 date range from the archeological evidence.

New analyses that use tree rings could settle the long-standing debate about when the volcano Thera erupted by resolving discrepancies between archeological and radiocarbon methods of dating the eruption, according to new research.
