Summary

[edit]
Description
English: Parascapular spine of Gigantspinosaurus sichuanensis.

Symtemtic position: Stegosuridae, Stegosauria, Ornithischia. Locality: Zhongquan, Zigong, Sichuan, China. Age: Late Jurassic (about 150 million years ago).

The comma-shaped parascapular spines of stegosaurs were once called "parasacral spines" and regarded as a pair of bones connected with pelvic girdles. The parascapular spines of Gigantspinosaurus sichuanensis, articulated symmethically with its shoulder bones, proved that the were a pair of special bones connecting with the shoulders of stegosaurs dinosaurus for the first time.

逗号形的肩棘曾叫做“副肩棘”，认为是关节在腰带上的一对骨骼。四川巨棘龙的这对骨骼与肩部骨骼对称关联保存在一起，首次确证了它们是长在剑龙类恐龙肩部的一对特殊骨骼。
