14:48, January 13, 2011

In a recent archaeological excavation of Wangjinglou heritage site in Xinzheng City of Henan Province, Zhengzhou Academy of Cultural Relics and Archaeology accidentally [say what?] discovered two large-scale ancient city ruins from the Xia and Shang dynasties with a total area of nearly 1.7 million square meters.

According to archaeologists' initial speculation, the city from the Xia period might have been the capital of a kingdom, while the city in Shang period might have been an important garrison town.

Here's the picture - those skeletons are not identified - don't have any idea if they are from the Xia period or the Shang period:

What the heck is wrong with the skulls of these skeletons?  They look deformed.  Oh oh - have the Chinese accidentally revealed evidence of ancient alien infestation of Mother Earth???
