Welcome to the McMaster Paleoethnobotanical Research Database. This database is run and designed by PhD candidate Shalen Prado from the Department of Anthropology at McMaster University.

This database is a collection of microbotanical specimens from modern and archaeological contexts and is designed to evolve alongside research projects at the McMaster Paleoethnobotanical research facility. You are able to browse by type of specimen (i.e. starch grain or phytolith) or you can search for a particular species by using the search bar.

If you have any questions please contact Shalen Prado at prados@mcmaster.ca
