DR. RICHARD LESURE, of the University of California in Los Angeles, California, received funding in January 2001 to aid research on the transition from the Archaic to the Formative period in Tlaxcala, Mexico. Archaeological research on early human settlement in the state of Tlaxcala has provided a basis for new understandings of the development of settled village life in the region. In this project, Lesure conducted geomorphological fieldwork and excavations at Formative villages. He documented several alluvial sequences in exposed cut-banks, although few Middle Holocene sequences were identified. At the village sites, numerous rich midden deposits containing evidence of domestic and ritual activities were documented. Radiocarbon dates for these occupations fell between 800 and 400 B.C.E. In general, the results of the research raised the possibility that sedentism developed in the area only after 1200 B.C.E., a topic to be explored in future work.
