HUNDREDS of human footprints dating back to about 20,000BC - the oldest in Australia and the largest collection of its kind in the world - have been discovered in Mungo National Park in western NSW.
They were left by children, adolescents and adults at the height of the last ice age as they ran and walked across a moist clay area near the Willandra Lakes.
Some people appear to have been hunting, with one very tall man sprinting at about 20kmh.
The first footprint was spotted by Mary Pappin Junior, of the Mutthi Mutthi people, two years ago and more than 450 more have been uncovered by a team led by Steve Webb of Bond University.
