It is a bone artifact unearthed from the Tomb of Shang Wang No. 1001, possibly made of elephant leg bones, with a complete lower end and a damaged upper end, and a rounded triangular cross-section of the body. On one of the corners of the body, there are two vertically arranged perforations at the lower position of the middle decorative band, which may be used to install handles. The decoration can be roughly divided into three parts. The upper and lower ends of the object are decorated with animal face patterns, the middle part is decorated with the main decoration of Taotie, and the two sides of the triangular pattern below are decorated with inverted dragons. Going further will be the Shen character decorative strip. These patterns are surrounded by dense cloud and thunder patterns, and the carvings are very exquisite. First stored at the Central Institute of Historical Research.
