Hueyatlaco

Valsequillo, area of the findings.

Hueyatlaco is an archeological site in the Valsequillo Basin near the city of Puebla, Mexico. After excavations in the 1960s, the site became notorious due to geochronologists' analyses, which have found wildly contradictory estimates for human habitation at Hueyatlaco dating from ca. 370,000 to 25,000 years before present (ybp).[1][2]

If correct, these controversial findings would substantially exceed the previous oldest-known evidence for habitation of the New World (the White sands footprints dating roughly 22,000 ybp). At the high end, they would imply that archaic humans settled the Americas prior to Homo sapiens, although such estimates are considered wildly implausible by archaeologists. As a result, the findings at Hueyatlaco are the subject of continued debate by the scientific community, and have seen only occasional discussion in the literature.[3]
