Conny Waters – AncientPages.com – Using a special type of radar, scientists have discovered “ghost” footprints dating as far back as the Pleistocene Era.
Invisible footprints hiding since the end of the last ice age offer valuable historical information about our ancestors.
The fossilized footprints reveal a wealth of information about how humans and animals moved and interacted with each other 12,000 years ago.

“We never thought to look under footprints,” said Thomas Urban, research scientist at Cornell and lead author on the study.
“But it turns out that the sediment itself has a memory that records the effects of the animal’s weight and momentum in a beautiful way. It gives us a way to understand the biomechanics of extinct fauna that we never had before.”
