With the development of a new method of cleaning charcoal called ABOx-SC, Michael Bird helped to push back the date of arrival of the first humans in Australia by more than 10,000 years.The calibrated date is also presented, either in BC or AD or with the unit cal BP (calibrated before present - before 1950).The calibrated date is our “best estimate” of the sample’s actual age, but we need to be able to return to old dates and recalibrate them because new research is continually used to update the calibration curve.Some of the first radiocarbon dates produced showed that the Scottish tombs were thousands of years older than those in Greece.The barbarians of the north were capable of designing complex structures similar to those in the classical world.
