Paleomagnetic dating absolute
This ancient human footprint with toe-prints and the arch preserved appeared briefly at Happisburgh.
It was made by a person walking along an ancient river and preserved in Lower Pleistocene sediment.
Image by Simon Parfitt, via PLo S ONE.3 Though erosion has erased much anatomical detail, a dozen feet were completely outlined. And in one the toes were clear.4 Analysis confirms the prints are like those of modern humans.
The feet that made these prints were attached to people about the same height as humans today.
These foot sizes suggest the people were 0.9 to 1.7 meters (about 3 to 5 ½ feet) tall.
Time and tide wait for no man, so scientists from the British Museum, London’s Natural History Museum, and Queen Mary University of London scrambled to get the seawater and sand mopped out of the prints for a better look before they disappeared two weeks hence.
The team photographed the prints from every conceivable angle and used computerized photogrammetrics to reconstruct them as three-dimensional images.
Homo antecessor fossils were found in the mid-1990s in Gran Dolina cave.
Their original date of 800,000 years has recently been revised after a paleomagnetic study6 and is now listed as 900,000.
