Archaeobotanical remains help us to reconstruct past vegetation and the ways in which humans interacted with their environment. We analyse phytolith, starch-grain and macrobotanical samples from selected archaeological contexts, including: i) archaeological features, for example habitation floors, midden refuse areas and funerary urns; ii) column samples from exposed excavation profiles; iii) residues extracted from plant-processing tools and containers recovered during excavations, such as plant grinding stones, stone grater teeth, ceramic containers and colanders. The archaeobotanical assemblages will be checked against the University of Exeter’s reference collection, which consists of over 500 modern plant specimens and is the largest Neotropical collection in Europe.
