From an article from Kaogu.net from september 2013:
A 4.000 year-old site in Xinjiang has yielded an unusual burial. This is an Andros Novo culture site in the Ili River Valley. At the Wutulan cemetery, archaeologists have found more than 200 tombs. They have excavatad eight and found three sacrificial platforms. Among these tombs was an unusual one that was very large; within it were a number of small stone sarcophaguses that had the remains of children. Each child was buried with a bowl. Local archaeologists believe that this site proves that the Andros Novo Culture was already dominant in the Ili River valley
