Abstract: | Fossil diatoms in the Valsequillo area are important in supplying adequate paleoecological evidence for the in situ deposition (in the absence of strong water currents necessary for the displacement and redeposition) of artifacts as large
as those at the Hueyatlaco Archaeological Site. The paleoecology of lacustrine diatom-bearing samples from four nearby localities
in the Valsequillo region all correlated with numerous diatomaceous samples from the Hueyatlaco Site (Puebla, Mexico) and
indicate an autochthonous deposition of the artifacts at that site. This correlative evidence is consistent with a deposition
in Sangamonian to Illinoian time and is based on the relationships of percentages of taxa in categories of the current, pH,
and halobian spectra in six lines of correlation of samples between the Hueyatlaco Site and the four localities. |
