G. Lockley, C. A. Meyer, V. F. Santos (2000). Megalosauripus and the problematic concept of megalosaur footprints. GAIA 15: 313–337. (low confidence: PBDB gives this publication for the name, but its author or year differ from the naming authority (Lessertisseur 1955): it may be a later work, such as one that renamed or redefined the genus).\n\nNot known or disputed:\n- Age: sources disagree (PBDB says 201.4–143.1 Ma; PBDB's own confirmed records says 168.2–113.2 Ma). Awaiting an Omnisaura editor.\n- Type species: no source Omnisaura uses gives this.\n- Order: 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- 26 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): Paleobiology Database (CC-BY-4.0); Wikidata (CC0-1.0)."
