This bone shuttle is made from wide and flat animal limb bones and is a component of a primitive loom.
Bone shuttles are found in many Neolithic sites around China. Their main function is to pull a weft yarn through the interlaced warp yarn so that the two can be quickly weaved together, thereby speeding up the changing speed of the loom and improving its accuracy. These bone shuttles are physical witnesses of the development of the textile technology at that time.
