B. Norman (2010). A taxonomy of iguanodontians (Dinosauria: Ornithopoda) from the lower Wealden Group (Cretaceous: Valanginian) of southern England. Zootaxa 2489: 47–66. https://doi.org/10.11646/zootaxa.2489.1.3 (medium confidence: only PBDB gives this; its author and year match the naming authority (Norman 2010)).\n- Diet, inferred by PBDB for the group: herbivore (medium confidence: only PBDB gives this, and it infers it for the whole of Ornithopoda, 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- Common names: no source Omnisaura uses gives this.\n- Named after: no source Omnisaura uses gives this.\n- 2 record(s) left out: pBDB fossil records identified only tentatively (for example 'cf.', '?', or the genus name in quotation marks, PBDB's mark for a loose use).\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)."
