"The 3,000-year-old tombs of a wealthy clan, including the remains of warriors and warhorses that seem to have been sacrificed at their funerals, have been unearthed in an ancient capital city of China." Source: Live Science.
"The complex of 24 tombs was discovered at an archaeological site within the city of Anyang in Henan province, less than 2 miles (2.4 km) from the UNESCO World Heritage archaeological site of Yinxu at the city's center. The ruins there are from the ancient city of Yin, the capital of the Shang dynasty, which ruled between about 1600 B.C. to 1046 B.C. — the earliest dynasty ever recorded in China.
"The newfound tomb complex includes several pits that hold war chariots, the remains of horses that drew them and the remains of warriors. Some of the warriors were wearing hats decorated with strings of shells when they died, while the foreheads of some of the horses were decorated with gold veneer and a bronze backing, according to a statement [Chinese language only with lots of pictures] from the government's Xinhua news agency."
Note: There is evidence that ritual suicides and voluntary live burials were conducted at this and other Shang dynasty sites:
According to a Penn State study, "A sizable portion of the oracle bones uncovered in Shang archaeological sites contain script specifically concerning human sacrifice ...These written records are also corroborated by the discovery of numerous sacrificial mass-graves in those sites. In most Shang sacrificial rituals, only animals and valuable chattels (such as bronze wares) would be used as offerings. There were only two exceptional circumstances where human sacrifices were made: xunzang 殉葬 and renji 人祭. Xunzang 殉葬 (lit. 'burial sacrifice') refers to the practice in which personal slaves and servants of Shang king, upon their master’s death, were expected to commit ritual suicide or to 'volunteer' themselves to be buried alive alongside with their master. While the practice of committing ritual suicide upon the master’s death has lingered throughout Chinese history, the second type of human sacrifice, renji 人祭 (lit. 'human offering sacrifice') is practiced only during the Shang dynasty period, and also the most massive in scale in terms of number of people killed in a typical renji ceremony."
