is usually given the rank of Suborder, within the order Ornithischia.
While ranked taxonomy has largely fallen out of favour among dinosaur
paleontologists, some researchers have continued to employ such a
classification, though sources have differed on what its rank should be.
Benton (2004) placed it as an infraorder within the suborder Cerapoda (originally named as an unranked clade), while others, such as Ibiricu et al. 2010, have retained it at its traditional ranking of suborder.
