In addition, samples need to be thoroughly cleaned to remove carbon contamination from glues and soil before dating.
This supported the idea that the classical worlds of Greece and Rome were at the centre of all innovations.These new techniques can have a dramatic effect on chronologies.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.Moving away from techniques, the most exciting thing about radiocarbon is what it reveals about our past and the world we live in.Radiocarbon dating was the first method that allowed archaeologists to place what they found in chronological order without the need for written records or coins.This method requires less than 1g of bone, but few countries can afford more than one or two AMSs, which cost more than A0,000.
Australia has two machines dedicated to radiocarbon analysis, and they are out of reach for much of the developing world.
In 2008 we could only calibrate radiocarbon dates until 26,000 years.
Now the curve extends (tentatively) to 50,000 years.
Luckily, we can measure these fluctuations in samples that are dated by other methods.
Tree rings can be counted and their radiocarbon content measured.
