  "summary": "Omnisaura summary: Coelophysis, Cope 1889\n\n- Named by: Cope 1889 (high confidence: PBDB and Wikidata agree).\n- Family: Coelophysidae (medium confidence: only PBDB gives this; nothing contradicts it).\n- Order: Saurischia (medium confidence: only NHM gives this; nothing contradicts it).\n- Parent group: Coelophysinae (medium confidence: only PBDB gives this; nothing contradicts it).\n- Age, as published by the Paleobiology Database: Norian to Sinemurian, 227.3–192.9 million years ago (low confidence: sources disagree and an editor has not ruled yet).\n- Age, Omnisaura's own calculation (not a published figure): 237–199.5 million years ago (medium confidence: Omnisaura's calculation from 21 confirmed PBDB records).\n- Fossils found in: United States (high: NHM and PBDB both record it).\n- Rock formations: Chinle (medium: only PBDB records it (9 records)); Petrified Forest (medium: only PBDB records it (8 records)); Bull Canyon Formation (low: only NHM gives this name and it matches no PBDB formation; awaiting an editor); Cooper Canyon (low: only one PBDB record); Dockum (low: only one PBDB record); Shuttle Meadow (low: only one PBDB record); Tecovas (low: only one PBDB record).\n- Original description: E. D. Cope (1889). On a new genus of Triassic Dinosauria. The American Naturalist 23: 626. (high confidence: PBDB gives this publication for the name; its author and year match the naming authority (Cope 1889), on which PBDB and Wikidata agree).\n- Diet, inferred by PBDB for the group: carnivore (medium confidence: only PBDB gives this; nothing contradicts it).\n- Way of life, inferred by PBDB for the group: ground dwelling, solitary (low confidence: PBDB infers this way of life for the whole of Theropoda; behaviour is rarely known for one genus).\n\nNot known or disputed:\n- Age: sources disagree (PBDB says 227.3–192.9 Ma; PBDB's own confirmed records says 237–199.5 Ma). Awaiting an Omnisaura editor.\n- Formations: sources disagree (NHM says Bull Canyon Formation). Awaiting an Omnisaura editor.\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- 5 record(s) left out: occurrences with status related_other_genus.\n- 4 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)."
