This article aims at demonstrating a new method of identifying ancient remains during surveys. It is suggested that archaeological sites can be observed in surveys based on the dispersion of the Onopordum cynarocephalum plant. This plant, a thistle, thrives on minerals, such as phosphorous and nitrogen, which are usually found in organically enhanced soils that are associated with human habitation throughout the ages; therefore, it can be used as an indicator of the existence of ancient remains.
