Diet often is reconstructed based on indirect evidence. Tooth tartar traps food particles, preserving a record of food consumed. Dental calculus removed from primary and secondary burials at Kichpanha was examined to identify imbedded phytoliths, starch granules, and debris as indicators of diet. The purpose of this study is to determine whether phytoliths and starch granules are preserved and recoverable from human dental calculus, to establish appropriate methods for this recovery and to...

Microfossil analysis is a technique used to better understand prehistoric diets. As part of a larger multinational project, we gathered and analyzed 112 samples of dental calculus (fossilized plaque) from human remains discovered at Paquimé and other sites in the Casas Grandes river valley to identify various microfossils still present in the silica matrix. With this information, we are able to better understand the flora present during ancient times and how it was used (food, processing, etc.).
