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- 2 record(s) left out: occurrences with status related_other_genus.\n- 25 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): Paleobiology Database (CC-BY-4.0); Wikidata (CC0-1.0)."
