The first datings of the artifacts using the thermoluminescence technique resulted in a range from 4420 BCE to 3400 BCE, which would have made the site the earliest Bronze Age culture in the world. However, with the 1974-1975 excavation, sufficient material became available for radiocarbon dating, which resulted in more recent dates.
During the first formal scientific excavation in 1967, several skeletons, together with bronze grave gifts, were unearthed. Rice fragments have also been found, leading to the belief that the Bronze Age settlers were probably farmers. The site's oldest graves do not include bronze artifacts and are therefore from a Neolithic culture; the most recent graves date to the Iron Age. Pots and sherds from the site are now found in museums across the world, including the Museum für Indische Kunst in Berlin and the British Museum in London
