 Wheeler published his findings in 1946 . He noted that , for the local fishermen of the village , the antiquities were strange — as they consisted of lamps , glass items , <unk> , <unk> and <unk> , wine containers , etc . He also observed that traders traveled from west coast and from Ceylon , <unk> ( <unk> ) and the Ganges area to trade goods such as gems , <unk> and spices , and silk . He carried out excavations carefully , so that none of the antiquities were damaged . This was followed by investigations after the war , from 1947 – 1950 by Jean @-@ Marie <unk> . His report of excavations was not as fully published as Wheeler 's . His report was not well @-@ known in India , as it was not written in English . However , his important conclusion was that the site belonged to an early megalithic period , as he had located megalithic burials marked by stones , locally known in Tamil as <unk> close to the site .
