Footprints dating back 20,000 years! Yes, I mean the Ice Age. Hundreds of human footprints of the age have been discovered in a dry lake bed in Australia. Scientists claim that they were the earliest footprint fossils found in the country. Adults, teenagers and children walking on and running across the moist clay flats near Willandra Lakes, southwest of Sydney, in the ice age, are claimed to have left this.
The prints range in size from 13 cm to 30 cm (5.1 to 11.8 inches). And this provides an insight into the anatomy and behavior of the people who left them. The scientists said this in an on-line report in the Journal of Human Evolution. It is said that the size of the prints and the pace lengths in most track-ways indicate tall individuals who were able to achieve high running speeds.
