The footprint is among the oldest evidence of human settlement in the Americas.
Researchers have discovered a human footprint in southern Chile they say is the oldest ever found in the Americas.
It took several years for the researchers to confirm that it was indeed a human footprint, and not that of an animal. Scientists classify fossil tracks by designating them as an “ichnospecies” rather than the more familiar “species” to avoid confusion, according to researchers Allison Vitkus, Karen Chin, and Martin Lockley—who were not involved in the study—writing on the University of California Museum of Paleontology’s website.
The Pilauco site—where excavations have been ongoing since 2007—contains the remains of ancient megafauna, such as mastodon and primitive elephants, as well as human tools. Thus, the latest findings, according to the Chilean team, might represent further evidence for the still-controversial idea of a pre-Clovis South American colonization of northern Patagonia, as originally indicated by the Monte Verde site.
