  "summary": "Omnisaura summary: Duriatitan, Barrett et al. 2010\n\n- Named by: Barrett et al. 2010 (medium confidence: only PBDB gives this; nothing contradicts it).\n- Order: Saurischia (medium confidence: only NHM gives this; nothing contradicts it).\n- Parent group: Titanosauriformes (medium confidence: only PBDB gives this; nothing contradicts it).\n- Age, as published by the Paleobiology Database: Kimmeridgian to Berriasian, 154.8–137.05 million years ago (high confidence: PBDB and NHM agree).\n- Age, Omnisaura's own calculation (not a published figure): 154.8–137.05 million years ago (medium confidence: Omnisaura's calculation from 5 confirmed PBDB records).\n- Fossils found in: United Kingdom (high: NHM and PBDB both record it); France (medium: only PBDB records it (2 records)).\n- Rock formations: Kimmeridge Clay Formation (high: NHM and PBDB both record it); Mont-Lambert (medium: only PBDB records it (2 records)).\n- Original description: P. M. Barrett, R. B. J. Benson, P. Upchurch (2010). Dinosaurs of Dorset: Part II, the sauropod dinosaurs (Saurischia, Sauropoda) with additional comments of the theropods. Proceedings of the Dorset Natural History and Archaeological Society 131: 113–126. (medium confidence: only PBDB gives this; its author and year match the naming authority (Barrett et al. 2010)).\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- Type species: no source Omnisaura uses gives this.\n- Family: 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- 3 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)."
