Among stegosaurids, only "Kentrosaurus" has been found with parascapular spines, which project posteriorly out of the lower part of the shoulder plates. These spines are long, rounded and comma-shaped in lateral view and have an enlarged base. "Loricatosaurus" was also believed to have a parascapular spine, but Maidment et al. (2008) observed that the discovered specimen, from which the spine is described, has a completely different morphology than the parascapular spine specimens of other stegosaurs. They suggest it may be a fragmentary tail spine instead. The genuine absence of parascapular spines in other stegosaurids is considered a secondary loss since many basal stegosaurs like "Gigantspinosaurus" and "Huayangosaurus" have been discovered with them.
