Mungo Man skeleton dates to 42,000 years old, oldest ever found in Australia. Mungo Lady and 106 other Indigenous skeletons excavated from Lake Mungo in 1960s-1970s. Discoveries rewrote Australian human history and led to World Heritage listing. Traditional owners Mutthi Mutthi, Paakantji, Ngiyampaa split on fate: reburial versus keeping place for science. Mungo Lady reburied 1992, Mungo Man 2017 and 2022. Remaining 106 skeletons now reburied in secret unmarked sites near original locations. Scientists like Michael Westaway call reburials destruction of history silencing 100 voices. Some traditional owners like Jason Kelly fight for public keeping place with protocols for Aboriginal scientists. Government approved reburials after consultations deemed extensive. Ongoing federal court case seeks to halt reburials and record sites. UNESCO alerted to potential World Heritage compromise. Other scientists like Nicola Stern say respect owners' decision as burials minor part of heritage.
