Dawenkou culture

The Dawenkou culture was a Chinese Neolithic culture primarily located in the eastern province of Shandong, but also appearing in Anhui, Henan and Jiangsu. The culture existed from 4300 to 2600 BC, and co-existed with the Yangshao culture. Turquoise, jade and ivory artefacts are commonly found at Dawenkou sites. The earliest examples of alligator drums appear at Dawenkou sites. Neolithic signs, perhaps related to subsequent scripts, such as those of the Shang dynasty, have been found on Dawenkou pottery. Additionally, the Dawenkou practiced dental ablation and cranial deformation, practices that disappeared in China by the Chinese Bronze Age.
