Truly Human-Made?

To make sure the footprints were indeed human, Gonzalez's team made 3-D images with a laser scanner, then compared them to human footprints made by volunteers marching up and down a beach in the United Kingdom.

"Now we are quite happy to give the word that these are indeed [human] footprints," she said.

"We know there were adults and children," she added, adding that looking at the prints was touching.

The laser scanning also had an unexpected side benefit: It preserved the data of the Mexico site, which is rapidly disappearing as road builders take stone from the quarry.

"Half the site is gone," Gonzalez said.

Because ancient footprint trails tend to be found in quarries and other vulnerable sites, mining and development are major problems for archaeologists.

"The problem is who is going to be responsible for the preservation of these sites," Gonzalez said.
