Fresh radiocarbon dating reveals Mohenjo-daro was occupied between 3300 and 2600 BCE, challenging the belief that urban development suddenly began around 2600 BCE. Excavations of a massive mud-brick structure first uncovered in 1950 by Sir Mortimer Wheeler show a multi-phase city wall dating to 2700-2600 BCE. Deep coring uncovered early Harappan style pottery, confirming the settlement evolved from an already established community rather than being built from scratch.
