Recently, archaeologists found prehistoric hats of human beings who lived 4,600 years ago from an ancient tomb site at Tongliao City of Inner Mongolia. Experts said it was the first time this kind of hats, which were made from bones, have been found in the same period of prehistoric culture.

As of now, archaeologists have found and cleared near 400 ancient tombs dating back 4,500 years ago around the site, and more than 1,500 objects of pottery, jade stone, horn and clam shell were excavated.

The newly-found bone hats were tightly cramped on dead bodies' heads and had the obvious shape of hats. After inspection, every such hat was made from 15 or 16 animal bones, and the length and radian of those are all very delicate.

Archaeologists have found four complete such "bone hats" from those 400 ancient tombs.
