<P> The bones of LM1 are thought to imply that after she died, the corpse was burned, then smashed, then burned a second time before being liberally covered with ochre, sourced from a location several hundred kilometres from the site . One suggested explanation for this behaviour is that the process was perhaps a ritual wherein the descendants tried to ensure that the dead did not return to haunt them . </P> <P> The bones were unconditionally repatriated in 1992 to the traditional owners, an alliance called the Three Traditional Tribal Groups (3TTG), consisting of the Paakantji, the Muthi Muthi, and the Ngiyampaa . LM1 had become a symbol of the long Aboriginal occupation in Australia, and an important icon for both archaeologists and indigenous Australians . LM1 is now in a locked vault at the Mungo National Park exhibition centre . The vault has a double lock and can be opened only if two keys are used . One key is controlled by archaeologists, the other by the local indigenous peoples . </P> <P> Lake Mungo 3 (LM3) was discovered by ANU geomorphologist Dr. Jim Bowler on 26 February 1974 when shifting sand dunes exposed the remains . LM3 was found near Lake Mungo, one of several dry lakes in the southeast part of the continent and 500m east of the LM1 site . The body had been laid out in great ceremony on its back, with knees bent and hands positioned at the groin with the fingers interlocked . Next to the body were the remains of fire . The body had been sprinkled with red ochre, in the earliest known example of such a sophisticated and artistic burial practice . This ritual burial aspect of the discovery has been particularly significant to Indigenous Australians, since it indicates that certain cultural traditions have existed on the Australian continent for much longer than previously thought . At the time of LM3's discovery, it was believed that Aboriginals had arrived in Australia from Asia around 20,000 years ago . Since the discovery of LM3, further archeological finds at Lake Mungo suggest that human occupation of the area dates as far back as 50,000 years ago . </P> <P> The skeleton had belonged to an individual who, based on evidence of osteoarthritis in the lumbar vertebrae, eburnation, and severe wear on the teeth with pulp exposure, was about 50 years old--relatively old for an early human--when he died . The bone structure had a gracile character, which contrasts with the morphology of modern indigenous Australians . Parts of the skeleton had deteriorated in situ: substantial portions of the skull were missing and most of the bones in the limbs have suffered surface damage . </P>
