  "summary": "Omnisaura summary: Compsognathus, Wagner 1861\n\n- Named by: Wagner 1861 (low confidence: PBDB and Wikidata agree on who named it but give years more than one apart; an editor has not ruled yet).\n- Family: Compsognathidae (high confidence: PBDB and NHM agree).\n- Order: Saurischia (medium confidence: only NHM gives this; nothing contradicts it).\n- Parent group: Compsognathidae (medium confidence: only PBDB gives this; nothing contradicts it).\n- Age, as published by the Paleobiology Database: Kimmeridgian to Tithonian, 154.8–145.06 million years ago (medium confidence: only PBDB gives this; nothing contradicts it).\n- Age, Omnisaura's own calculation (not a published figure): 154.8–145.06 million years ago (medium confidence: Omnisaura's calculation from 4 confirmed PBDB records).\n- Fossils found in: France (medium: only PBDB records it (2 records)); Germany (low: only one PBDB record); Portugal (low: only one PBDB record).\n- Rock formations: Alcobaça (low: only one PBDB record); Painten (low: only one PBDB record).\n- Original description: J. A. Wagner (1861). Neue Beiträge zur Kenntniss der urweltlichen Fauna des lithographischen Schiefers [New contributions to the knowledge of the ancient fauna of the lithographic slates]. Abhandlungen der königlichen bayerische Akademie der Wissenschaft, II Classe 9(1): 65–124. (medium confidence: only PBDB gives this; its author and year match the naming authority (Wagner 1861)).\n- Diet, inferred by PBDB for the group: carnivore, insectivore (medium confidence: only PBDB gives this; nothing contradicts it).\n- Way of life, inferred by PBDB for the group: ground dwelling (medium confidence: only PBDB gives this; nothing contradicts it).\n\nNot known or disputed:\n- Authority: sources disagree (PBDB says Wagner 1861; Wikidata says Johann Andreas Wagner, 1859). Awaiting an Omnisaura editor.\n- Type species: 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\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)."
