Silesaurid subgroups
Sulcimentisauria refers to all taxa more closely related to Silesaurus than to Asilisaurus. Most silesaurids qualify as sulcimentisaurians, since Asilisaurus diverged early in the group's evolution. Sulcimentisauria was originally named with the understanding that silesaurids are a non-dinosaurian clade. It has seen continued use by some supporters of the ornithischian hypothesis as well. A few studies prefer not to reuse it beyond its narrow original context of a silesaurid clade. Parapredentata is a clade name exclusive to the ornithischian hypothesis, referring to the least inclusive clade containing Silesaurus and Iguanodon.
