A trail of 13 fossilized footprints running through a valley in a desert in northern Mexico could be among the oldest in the Americas, Mexican archeologists said.
From Yahoo! News:
The footprints were made by hunter gatherers who are believed to have lived thousands of years ago in the Coahuila valley (photo) of Cuatro Cienegas, 190 miles (306 kms) south of Eagle Pass, Texas, said archaeologist Yuri de la Rosa Gutierrez of Mexico's National Institute of Anthropology and History.
"We believe (the footprints) are between 10,000 and 15,000 years old," De la Rosa said. "We have evidence of the presence of hunter gatherers in the Coahuila desert more than 10,000 years ago."
The oldest discovered footprints in the Western hemisphere are in Chile, and are believed to be 13,000 years old. There 6,000-year old footprints in the U.S. state of California, in Brazil and in Nicaragua.
The age of the Mexican footprints is dwarfed by those found in Africa. The oldest known hominid foot marks are in Laetoli, in Tanzania, and are believed to have been made 3.5 million years ago.
