This is a question from Instituto de Investigaciones Antropologicas in
Mexico City. Our archaeologists are studying ancient floors from
Teotihuacan, some of them are made of dirt and others of stucco. So far
they have been able to identify food remains by analyzing remains of seeds,
pollen, phytolites, and some inorganic indirect tracers such as phosphorus.
They are now planning to simulate ancient house floors and see how food
remains are preserved, and how their remains can be identified. Has any of
you done similar studies, or have an idea of other remains that should be
sought?
