Abstract

This masters thesis in dental anthropology and bioarchaeology examines discrete, non-metric dental data collected from skeletal remains of a Middle Formative era Mexican population at EI Pantano. This site is situated in Jalisco, West Mexico, and represents one of the earliest archaeological examples of transitional agriculture for this area. Materials recovered from the burials suggest that the yet-undiscovered settlement whose people used the cemetery had complex interactions with diverse Mexican groups, including the OImec-linked site of Tlatilco in the Valley of Mexico, and also with groups as far away as Guatemala and the Andes mountains. Phenetic analysis of dental morphology shows results which are consistent with biological affinity between El Pantano and Andean populations, and also suggests that Tlatilco may be among the population's loser relationships within Mexico.
