Lake Mungo remains
The skeleton was of a slender individual, quite different to the build of modern indigenous Australians. The skeleton was badly preserved: large pieces of the skull were missing, and most of the bones in the limbs were damaged. Usually, the gender of a  skeleton is determined using the bones in the skull and the pelvis. 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.
