The Dadiwan culture (c. 7900–7200 BP) was a Neolithic culture located primarily in the eastern portion of Gansu and Shaanxi provinces in modern China. The culture takes its name from the deepest cultural layer found during the original excavation of the type site at Dadiwan. The remains of millet, pigs and dogs have been found in sites associated with the culture, which is itself defined by a thin-walled, cord-marked ceramic tradition sometimes referred to as Laoguantai. The Dadiwan culture shares a variety of common features, in pottery, architecture, and economy, with the Cishan and Peiligang cultures to the east.
