The prehistory of Sri Lanka covers the Palaeolithic, Mesolithic and early Iron Age of the country until the Pre Anuradhapura period in 543 BC. There is evidence of Paleolithic (Homo erectus) people in Sri Lanka from about 300,000 BP and possibly even as early as 500,000 BP. There is strong evidence of prehistoric settlements in Sri Lanka by about 125,000 BP. Evidence of a transition between the Mesolithic and the Iron Age is scant.
