  "summary": "Omnisaura summary: Syntarsus, Raath 1969\n\n- Named by: Raath 1969 (medium confidence: only PBDB gives this; nothing contradicts it).\n- Parent group: Coelophysoidea (medium confidence: only PBDB gives this; nothing contradicts it).\n- Age, as published by the Paleobiology Database: Rhaetian to Pliensbachian, 205.7–184.2 million years ago (low confidence: sources disagree and an editor has not ruled yet).\n- Age, Omnisaura's own calculation (not a published figure): 205.7–184.2 million years ago (medium confidence: Omnisaura's calculation from 10 confirmed PBDB records).\n- Fossils found in: United States (medium: only PBDB records it (6 records)); South Africa (medium: only PBDB records it (4 records)); Zimbabwe (low: NHM records it here but PBDB has no record in this country; awaiting an editor).\n- Rock formations: Elliot Formation (medium: only PBDB records it (4 records)); Kayenta (medium: only PBDB records it (5 records)); Forest Sandstone (low: only NHM gives this name and it matches no PBDB formation; awaiting an editor); Moenave (low: only one PBDB record).\n- Original description: M. A. Raath (1969). A new coelurosaurian dinosaur from the Forest Sandstone of Rhodesia. Arnoldia (Rhodesia) 4(28): 1–254. (medium confidence: only PBDB gives this; its author and year match the naming authority (Raath 1969)).\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- Age: sources disagree (PBDB says 205.7–184.2 Ma; NHM specimens says 237–201.4 Ma). Awaiting an Omnisaura editor.\n- Formations: sources disagree (NHM says Forest Sandstone). Awaiting an Omnisaura editor.\n- Countries: sources disagree (PBDB says US, ZA; NHM says Zimbabwe). Awaiting an Omnisaura editor.\n- Type species: no source Omnisaura uses gives this.\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- 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)."
