Based on this, it is likely that LM3 was quite old (around 50 years old) when he died.
The first estimate of LM3's age was made in 1976 by the team of scientists from the Australian National University (ANU) who excavated LM3.
Optical dating concluded that both LM1 and LM3 were buried around 40,000 years ago (plus or minus 2,000 years). The body was covered with red ochre, in the earliest known example of such a complicated and artistic burial practice.
Like the cremation of LM1, this indicates that certain cultural traditions have existed on the Australian continent for much longer than previously thought.
The patterns of burn marks on the bones suggest that the body was first burned, then smashed, then burned a second time, before being buried.
Research published by Bowler in 2003 rejected previous estimates for all of remains at the site.
Some of the bones show evidence of osteoarthritis and eburnation, and the teeth are well worn.The Lake Mungo remains are three sets of human fossils.They are Lake Mungo 1 (LM1, or Mungo Lady), Lake Mungo 2 (LM2), and Lake Mungo 3 (LM3, or Mungo Man).The problem is that these bones are in a very bad state in LM3, or they are missing altogether; in other words, the "normal" method of gender determination cannot be used with LM3.Since LM3 was discovered, other features were studied; most of these studies agree that LM3 was probably a male.
