Heterodontosauriformes were a proposed group of herbivorous dinosaurs within the order Ornithischia. The taxon was named by Xu et al. in 2006 to group the suborder Marginocephalia with the family Heterodontosauridae (previously classified as ornithopods), after the discovery of Yinlong revealed the two to be closely related.[1] Later studies failed to recover the group and it has been largely abandoned.[2]
