The Post Graduate Institute of Archaeology (PGIAR), University of Kelaniya, is currently engaged in an archaeological excavation of a place assumed to be a proto historic burial site. This site is the newest addition to the fifty odd archaeological sites representing the early Iron Age of Sri Lanka. According to the surface evidence of the site it is assumed to be a clay canoe burial. The archaeological findings from Ranchamadama in Hambantota District and Kalaotuwawa in Gampaha District have revealed similar types of burials.

Applications of Geological methodologies in archeological research have been rapidly increased around the world and developed as a new field known as Geo archaeology. The field Geo archaeology provides the knowledge and the skills to understand the site formation processes, human occupations and their activities. Particle size analysis, organic matter content and phosphate analysis of sediments are commonly used techniques in Geo archaeological studies. Sediments from an excavation carried out in Varana rock shelter no 5, which is a prehistoric site were analyzed by above mentioned Geo archeological methods to study stratigraphic of the sediment layers and prehistoric human occupation.
