Scientific excavation by the Penn Museum and the Thai Fine Arts Department took place at the site of Ban Chiang in northeast Thailand in 1974 and 1975. These excavations uncovered a thriving and hitherto unknown prehistoric culture dating from 5000 years ago and led to the rewriting of Southeast Asian prehistory.
The Metal Age village and mortuary site of Ban Chiang is in the province of Udon Thani in northeastern Thailand.
The Ban Chiang Project's studies cover the Inital Period of occupation (? - 2100 BCE) to the Late Period (300 BCE - 200 CE)
