}}Heterodontosauriformes was 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 suggested the two were closely related.[1] However later studies failed to recover the group and it has been largely abandoned.[2] References1. ^{{cite journal |last=Xu X. |author2=Forster, C.A. |author3=Clark, J.M. |author4= Mo J. |year=2006 |title=A basal ceratopsian with transitional features from the Late Jurassic of northwestern China |journal=Proceedings of the Royal Society B: Biological Sciences |volume=273 |pages=2135–2140 |doi=10.1098/rspb.2006.3566 |pmid=16901832 |pmc=1635516 |first1=X. |issue=1598}} {{Portal|Dinosaurs}}{{Taxonbar|from=Q2128549}}{{ornithischian-stub}}2. ^{{Cite journal|author1=Fenglu Han |author2=Catherine A.
