Mungo man carbon dating

Thursday, 20 May C. Johnson, The Lab. Mungo Man - part of a civilisation that arrived in Australia nearly 70, years ago at least. New tests on an ancient skeleton suggest the first humans may have arrived in Australia as long as 78, years ago - more than 10 years earlier than previously thought.

Lake Mungo

Fresh analysis of the skeletal remains found at Lake Mungo in NSW 25 years ago indicate he may be up to 68, years old - making him 28, years older than earlier scientific estimates. The revised dating of the remains by scientists at the Australian National University rewrites the history of Australia's occupation and has profound implications for worldwide debate over the origins of modern man. Cross-matching a range of recent dating tests puts the minimum date of the burial of the remains at 56, to 68, years ago.

The research, to be published today in the Journal of Human Evolution , came up with almost identical dates. But the researchers add that the location of the Mungo skeleton, deep in Australia's south-east, suggests Homo sapiens arrived in the north-east much earlier, taking time to migrate inland and adapt to desert conditions before travelling down the continent. The previous accepted estimate was that humans had roamed the country for 40, to 60, years.

The redating was carried out using three different methods - uranium series, electron spin resonance and optically stimulated luminescence. The researchers say they date the remains at 62, years, plus or minus years. The findings strengthen the theory that two forms of man - the delicate people first and the robust people later - came to the outer reaches of the continent from two different parts of Asia tens of thousands of years ago.

These groups, along with others that came later, are then said to have merged to form modern Aborigines and Melanesians. The finding is certain to spark renewed debate between the multi-regionalists, who believe different people migrated from different parts of Asia, and those who support the "out of Africa" model that dates all human origin to Africa. The discovery began more than a quarter of a century ago, when on 26 February , the shifting sands of a lunette around Lake Mungo in the Willandra Lakes World Heritage area revealed an eroding gravesite.

It was a human skeleton - known as Lake Mungo 3 - that had been covered in red ochre during a burial ritual. The hands were interlocked and positioned over the penis. Five years earlier the cremated remains of a female skeleton, known by local Aborigines as Mungo Lady, were found in the same area. Using carbon-dating, a technique only reliable to around 40, years old, the skeleton was first estimated at 28, to 32, years old.

The figures were later revised upwards to about 40, years old. Dr Thorne said the new research also provided new minimum ages for human cremation and the use of ochre in burials. The burial of Mungo Man involved the spreading of red ochre over the body during the burial ceremony. This is the earliest known use of pigment for artistic, philosophical or religious purposes.

Carbon has a half-life of 5, years so dating is limited to between a few of Mungo Lady and Mungo Man, and the layers above and below the footprints. When archaeologists used different scientific dating techniques, mathematics had to be used. For example, radio carbon dating. The measurement of carbon.

A University of Melbourne-led study has finally got scientists to agree on the age of Mungo Man, Australia's oldest human remains, and the consensus is he is 22, years younger. A University of Melbourne-led team say Mungo Man's new age is 40, years, reigniting the debate for the 'Out of Africa' theory. The research also boosted the age of Mungo Lady, the world's first recorded cremation, by 10, years putting her at the same age as Mungo Man. It is the first time scientists have reached a broad agreement on the ages of the Lake Mungo remains.

Lake Mungo is one of 17 dried Pleistocene Epoch about 2. In Bowler discovered the complete skeleton of a man, known as Mungo Man.

Scientific Methods That Have Been Used to Study the Remains In order to maintain the condition that this bog body was originally found in, medicine has been used to analyse the body and its condition. As a result further damage has been avoided.
