identical and tend shift with changes in ocean circulation. Pascale Richardin, Magali Coudert, Nathalie Gandolfo, Julien Vincent. During the Predynastic period, progress becomes faster and faster, so much happens, he says. In the 19th century it was common for Western tourists and scholars who journeyed to Egypt to bring home mummies, coffins, and other artefacts as souvenirs, Dr Sowada said. The problem, says Bronk Ramsey, is that tree rings provide a direct record that only goes as far back as about 14,000 years. As a rule, carbon dates are younger than calendar dates: a bone carbon-dated to 10,000 years is around 11,000 years old, and 20,000 carbon years roughly equates to 24,000 calendar years. The researchers collected roughly 70-metre core samples from the lake and painstakingly counted the layers to come up with a direct record stretching back 52,000 years. To improve on that, Dee and his colleagues used a computerised statistical approach known as Bayesian modelling. It started with small, cattle-owning communities who migrated with the seasons. They entered these into a computer model to estimate the most likely dates of transition between the different periods. Perhaps most surprisingly, 2005 research (based on CT scans and other data) revealed mummy NM R27.3 was actually a man inside the coffin of a woman.

Early Egypt might have been ruled by individual kings, some of their names are inscribed on the Palermo Stone (Image: courtesy of the Petrie Museum, UCL).

Research published in 2005 showed mummy NM R27.3 was actually a man not a woman, and nuclear science techniques tonnsee sex treffen are now helping piece together more of the puzzle. The radiocarbon dating we are doing now will help us get a lot closer to understanding when this person lived. This plaster was painted red and green in imitation of the god Osiris. G√ľnter Dreyer who, until recently, was the director of the German Archaeological Institute in Cairo, and has led excavations at Abydos, one of ancient Egypts oldest cities, for more than 30 years.

Five thousand years ago, Egypt became the worlds first territorial state with strict borders, organised religion, centralised administration and intensive agriculture. Climate records from a Japanese lake are set to improve the accuracy of the dating technique, which could help to shed light on archaeological mysteries such as why Neanderthals became extinct. He is sceptical about the accuracy of radiocarbon measurements when it comes to absolute dates, but agrees the technique gives a valuable indication of the lengths of different historical periods. The research we are doing in Sydney really has major implications for collections across the country and across the world particularly those in smaller museums which have acquired mummies from private sources as opposed to archaeological excavations. As the decades passed on, many of these antiquities transferred from private collections to museums where we are now starting to discover they are not all what we first thought. To minimize the sample size, we have developed a new method for the pretreatment of hair samples before accelerator mass spectrometry (AMS) radiocarbon dating. Radiocarbon and peer reviewed, and pending that, published next year. Similarly, a hair sample from the head of a mummy presents a very different 14C date from that of the hair across her chest.
