Plant macro-fossil remains can include all parts of plants, seeds and other fruiting bodies, flower parts, buds, leaves, branches, roots and tubers. They are found in a diverse range of environments, terrestrial and aquatic. The plant remains found on archaeological sites represent plants that grew on the site and those that were brought in e.g. cereals, weeds or building materials. The study of all plant macro-fossils can contribute to an understanding of past economies and environments (including seasonality) and can show the selective exploitation of plants for food and other uses.
