Proceedings of the Royal Society of London B 270(1525): 1753–1758. https://doi.org/10.1098/rspb.2003.2417 (high confidence: PBDB gives this publication for the name; its author and year match the naming authority (Yates and Kitching 2003), 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 Sauropoda, 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 Sauropoda; behaviour is rarely known for one genus).\n\nNot known or disputed:\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.
