Journal of Vertebrate Paleontology 23(3): 556–574. https://doi.org/10.1671/a1097 (medium confidence: only PBDB gives this; its author and year match the naming authority (Dzik 2003)).\n- Diet, inferred by PBDB for the group: herbivore (medium confidence: only PBDB gives this; nothing contradicts it).\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- Order: 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.
