A 15,600-year old human footprint

A 15,600-year old human footprint discovered in southern Chile is believed to be the oldest ever found in the Americas, according to researchers. The footprint was first discovered in 2010 by a student at the Universidad Austral of Chile. Scientists then worked for years to rule out the possibility that the print may have belonged to some other species of animal, and to determine the fossil’s estimated age.Reuters
