  "summary": "Omnisaura summary: Coelurus, Marsh 1879\n\n- Named by: Marsh 1879 (medium confidence: only PBDB gives this; nothing contradicts it).\n- Parent group: Coelurosauria (medium confidence: only PBDB gives this; nothing contradicts it).\n- Type species: Coelurus fragilis (medium confidence: only PBDB gives this; nothing contradicts it).\n- Age, as published by the Paleobiology Database: 157.9–113.2 million years ago (medium confidence: only PBDB gives this; nothing contradicts it).\n- Age, Omnisaura's own calculation (not a published figure): 154.8–143.1 million years ago (medium confidence: Omnisaura's calculation from 8 confirmed PBDB records).\n- Fossils found in: United States (medium: only PBDB records it (8 records)).\n- Rock formations: Morrison Formation (medium: only PBDB records it (8 records)).\n- Original description: O. C. Marsh (1879). Notice of new Jurassic reptiles. The American Journal of Science and Arts, series 3 18: 501–505. https://doi.org/10.2475/ajs.s3-18.108.501 (medium confidence: only PBDB gives this; its author and year match the naming authority (Marsh 1879)).\n- Diet, inferred by PBDB for the group: carnivore (medium confidence: only PBDB gives this, and it infers it for the whole of Coelurosauria, 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, 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- Order: 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- 6 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)."
