The Hueyatlaco archaeological site is in the Valsequillo Basin near this city of Puebla, Mexico. Excavation began at the site in 1962 and a wide array of stone tools was found. The team was led by Cynthia Irwin-Williams, and Virginia Steen-McIntire has been associated with the site, first in joining the team as a graduate student in 1966 and later in publicising research results.



Hueyatlaco is highly significant because geo-chronological dating of the artifacts, taking to be used by early humans, gives an age of 250,000 before the present, whereas orthodox archaeology takes humans, Homo Sapiens, to only have evolved 100,000 years ago. Since 1969 this research has been subjected to scientific critique, but the objections have been systematically answered by further research.


Sam L.VanLandingham in "Corroboration of Sangamonian Age of Artifacts from the Valsequillo Region, Puebla, Mexico by Means of Diatom Biostratigraphy", Micropaleontology, vol.50, 2004, pp.313-342, gives a date of between 80,000 to 220,000 years BP, based on an analysis of diatoms, microscopic unicellular algae. A more recent paper by VanLandingham is "Use of Diatoms in Determining Age and Paleoenuronment of the Valsequillo (Hueyatlaco) Early Man Site, Puebla, Mexico, with Corroboration by Chrysophyla Cysts for a Maximum Yarmouthian (430,000 - 500,000 yr BP) Age of the Artifacts", Nova Hedwigia, Beiheft, vol.136, 2010, pp.127-128. Then it is stated that the latest analysis using diatoms yields an even older age for the artifacts : "The extinctions and earliest known first occurrences of the 26 extant and eight extinct cyst taxa in the three samples (with a minimum 430,000 yr BP Yarmouthian age) corroborate a likely maximum of 430,000 yr BP for the Hueyatlaco artifacts which previously were established by means of diatom/cyst assemblages with a maximum age of Illinoian (ca 220,000 - 430,000 yr BP)". (p.127)


An age of up to 430,000 years for the Hueyatlaco artifacts logically implies that humans existed at that time, as the artifacts are characteristically those of humans. The ruling "Out of Africa" orthodoxy holds that modern human only came into existence 100,000 years ago. In his paper "Forbidden Archaeology and the Knowledge Filter", Pleistocene Coalition News, vol.2, no.2, March-April, 2010, Michael A.Cremo points out that if one examines the primary scientific literature, in languages other than English, there can be found much evidence refuting the archaeological orthodox view.
[For example, 19th century mining at the Table Mountains near the town of Sonora in Tuslumne County, California, led to the discovery of human bones and artifacts in early Eocene deposits of about 50 million years old! The chief government geologist of California at that time, Dr J.D.Whitney, documented this in a publication, The Auriferous Gravels of the Sierra Nevada of California, which was published by Harvard University's Museum of Comparative Zoology in 1880. Much more is contained in a book published in 1993 by Michael A.Cremo and Richard L.Thompson, Forbidden Archaeology, which I have yet to read, but will review at this site when I have obtained it.]



Once more we see how "facts" are discounted and rejected because they do not fit the ruling theory of the time. This debate is highly significant because it has the potential to not only overturn established archaeology but also the present consensus on the age of Homo sapiens and the origin of the races.
