  "summary": "Omnisaura summary: Becklespinax, Olshevsky 1991\n\n- Named by: Olshevsky 1991 (medium confidence: only PBDB gives this; nothing contradicts it).\n- Order: Saurischia (medium confidence: only NHM gives this; nothing contradicts it).\n- Parent group: Tetanurae (medium confidence: only PBDB gives this; nothing contradicts it).\n- Age, as published by the Paleobiology Database: Berriasian to Valanginian, 139.1–132.6 million years ago (medium confidence: only PBDB gives a range this precise; NHM's records give only a broader interval, which contains it).\n- Fossils found in: United Kingdom (low: NHM records it here but PBDB has no record in this country; awaiting an editor).\n- Original description: G. Olshevsky (1991). A revision of the parainfraclass Archosauria Cope, 1869, excluding the advanced Crocodylia. Mesozoic Meanderings 2: 1–196. (medium confidence: only PBDB gives this; its author and year match the naming authority (Olshevsky 1991)).\n- Diet, inferred by PBDB for the group: carnivore (medium confidence: only PBDB gives this, and it infers it for the whole of Theropoda, 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- Countries: sources disagree (PBDB says ; NHM says United Kingdom). Awaiting an Omnisaura editor.\n- Type species: no source Omnisaura uses gives this.\n- Family: no source Omnisaura uses gives this.\n- Age (confirmed evidence): no source Omnisaura uses gives this.\n- Formations: 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- 1 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)."
