Résumé
A review of the Valsequillo archaeological finds from the last century is given, such as the cranial remains (Dorenburg and Ostrander skulls), the engraved bone fragments, butchering marks, green bone fractures and flint points and scrapers. However, most of these finds are now missing. Their original dating is reviewed, along with the controversial Uranium Series and Fission Track dates from Hueyatlaco. Further relative dating techniques, such as the use of diatoms and bone assemblages, are discussed. Recently human and animal footprints from the Xalnene Ash at Toluquilla quarry have been described, mapped and dated by optically stimulated luminescence, and there has been new dating of the Valsequillo Gravels by AMS radiocarbon dating of molluscs and electron spin resonance of mammoth bone. The Xalnene Ash dates have proved controversial and the dating issues are reviewed. A suggested dating framework for the Valsequillo sequence in which the archaeological artefacts and footprints are found is given and all the stratigraphy with archaeological remains is considered to be Late Pleistocene in age.
