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\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 fossil record(s) left out because their identification is uncertain.\n\nNot covered by Omnisaura: diet, size, weight, appearance or behaviour. 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)."
