A. Hopson (1975). On the generic separation of the ornithischian dinosaurs Lycorhinus and Heterodontosaurus from the Stormberg Series (Upper Triassic) of South Africa. South African Journal of Science 71: 302–305. (high confidence: PBDB gives this publication for the name; its author and year match the naming authority (Hopson 1975), on which PBDB and Wikidata agree).\n- Diet, inferred by PBDB for the group: herbivore (medium confidence: only PBDB gives this, and it infers it for the whole of Ornithischia, the group this genus belongs to, not from this genus's own fossils).\n- Way of life, inferred by PBDB for the group: ground dwelling, gregarious (low confidence: PBDB infers this way of life for the whole of Ornithischia; behaviour is rarely known for one genus).\n\nNot known or disputed:\n- Type species: no source Omnisaura uses gives this.\n- Common names: no source Omnisaura uses gives this.\n- Named after: no source Omnisaura uses gives this.\n\nNot covered by Omnisaura: size, weight, appearance, or behaviour beyond the way of life PBDB infers for the group. Do not fill these in from general knowledge as if they came from Omnisaura.\n\nCredits (must be shown with any of this): Natural History Museum Data Portal (CC0-1.0); Paleobiology Database (CC-BY-4.0); Wikidata (CC0-1.0)."
