Ancient human footprints discovered in the Mexican desert may be among the oldest in the Americas, researchers said on Wednesday. The 13 footprints found in Cuatro Cienegas in the northern state of Coahuila are fossilized in stone less than an inch deep and are around the age of the oldest known footprints in North or South America – they could be between 10.000 and 15.000 years old. The oldest discovered human footprints in the New World are in Monte Verde, Chile and are believed to be around 13.000 years old. The earliest known hominid tread marks are the Laetoli footsteps in Tanzania. At 3.7 million years old, they far predate the advent of homo sapiens.
