Green crystals found in 2,500-year-old Chinese tomb
Chinese archaeologists exploring a 2,500-year-old tomb in east China's Jiangxi province that contained 47 coffins in a remarkable state of preservation were stunned to discover several pieces of green crystal lodged in the bones of the skeletons in the coffins. One of the diamond-shaped crystals was 8.5 centimeters long. The coffins also contained bronze, gold, silk, porcelain and jade items and even body tissue.
Archaeologists said the crystals appeared to have 'grown' in the bones. They pointed out that the coffins were made from halved nanmu, a rare and extremely durable wood, and covered in white plaster and a layer of loess. The fact that the coffins were fire-heated to make them waterproof and airtight may be a factor in the creation of the crystals. Archaeologists said there were no previous records of green-colored crystals being found in tombs and said they would help scientists understand changes to the human body in different conditions.
Discovered in December 2006, the tomb in Lijia village in Jing'an county in Jiangxi is 16 meters long, about 11.5 meters wide and three meters deep. It is believed to date back to the Eastern Zhou Dynasty (770-221 BCE). This is the largest group of coffins ever discovered in a single tomb in China. Scientists say that the body tissue discovered in the coffins are human brains that have shrunk to the size of a fist but retained their original structure complete with two cerebral hemispheres, cerebel and brainstem. "This is the first time such complete old brain structures have been found in southern China and they will be extremely useful for the study of humans in the pre-Qin era (770-221 BCE)," said Zhu Hong, a palaeoanthropological expert from Jilin University.
Zhu said the unique burial style could explain why the skeleton and the brain tissue had been preserved so well in an area where the soil was acidic and unsuited to the preservation of human bodies.
The coffins, 2.5 to 2.8 meters long and 0.5 meters wide, were laid out side by side in an orderly fashion. Thirteen of the coffins have now been transferred to a nearby storehouse to be kept in a temperature and humidity-controlled environment.
