The Altica Project, that began in 2014, is an important step in addressing the limited problem-oriented research at Formative sites in the Basin of Mexico for over two decades. Altica is the earliest-known settled village in the Teotihuacan Valley and one of the only first-farming village sites in the Basin of Mexico that has not been engulfed by the urban sprawl of Mexico City. Despite its small size and remote location, Altica was an important piece in Early and Middle Formative exchange...
Early agrarian societies in the Basin of Mexico: Challenges and Perspectives (2015)
Over the past three decades, there have been very few studies of the earliest agrarian communities in the Basin of Mexico in comparison with other periods. In this paper, we introduce the symposium with an evaluation of the state of knowledge concerning preceramic, archaic communities up to the Formative period in the Basin of Mexico, with particular emphasis on the dearth of information available concerning paleoenvironment and subsistence. We review some of the recent investigations in the...
Expanding radiogenic strontium baseline data for central Mexican paleomobility studies (2017)
Radiogenic strontium (87Sr/86Sr) isotope values reflect local geology and have long been used in analyses of paleomobility within Mesoamerica. Research has focused on reconstructing individuals’ residential histories by comparing strontium isotope ratios in individuals’ tooth enamel and bone with local baseline values generated from soils, plants, or local fauna. While a great deal of work has been done developing baseline values across the Maya region, work in central Mexico is predominantly...
Paleoindian Sites from Central Mexico: Paleoenvironment and Dating (2018)
During the last 20 years we have studied systematically several important Paleoindian sites from Central Mexico doing detailed stratigraphic studies, paleoenvironmental reconstructions (pollen, diatoms, tephra studies) and radiocarbon dating. The sites include: Peñon Woman III skeleton, Santa Isabel Iztapan Mammoths with associated lithics, Tlapacoya Man Skull, Tocuila Mammoths, Tequixquiac Late Pleistocene Fossils and Tepexpan Man Skeleton. We present here a general model of strong...
Paleosols and human activities in the lakebed area of Basin of Mexico during the Middle Holocene (2015)
During 2013 - 2014 archaeological research was undertaken in San Gregorio (Xochimilco) and Tepexpan, Basin of Mexico, to recover evidence for human activity associated to the preceramic period in the lakebed area of Chalco-Xochimilco and Texcoco. One of the specific objectives of this research is to characterize soil conditions north and south of modern Mexico City, during the early agriculture period (6500-4000 BP) by means of paleopedological analysis, and evaluate environmental and...
Procedencia e Intercambio de obsidiana durante el Holoceno Medio en la Cuenca de México (ca. 6200-5000 calBP). Un análisis mediante pXRF (2015)
Se caracterizó mediante análisis de Fluorescencia de Rayos X (XRF) un conjunto de obsidianas obtenidas en las excavaciones en el sitio de Tepexpan, Edo. de México y San Gregorio Atlapulco, Xochimilco, D.F. (n=149), procedentes de los niveles precerámicos de ambos sitios, através del análisis de diversos elementos (Na, K, Ti, Mn, Fe, RB, Sr, Y, Zr, Nb y Ba); esto nos permitió conocer la composición química de cada uno de los artefactos líticos para posteriormente efectuar comparaciones con...
Style, Memory, and the Production of History: Aztec Black-on-Orange Pottery in Xaltocan, Mexico (2017)
This paper will explore shifting patterns in ceramic consumption and stylistic design during the Postclassic period (AD 900-1350) at the site of Xaltocan in the Basin of Mexico. Xaltocan is the only site in the northern Basin of Mexico associated with a large percentage of early Black-on-Orange pottery. This same pottery is rare at contemporaneous sites located a few kilometers away. Because Black-on-Orange ceramics were used by elites and commoners alike, and also cross-cut various ethnic and...
