  "summary": "Omnisaura summary: Dacentrurus, Lucas 1902\n\n- Named by: Lucas 1902 (low confidence: sources disagree and an editor has not ruled yet).\n- Family: Stegosauridae (high confidence: PBDB and NHM agree).\n- Parent group: Dacentrurinae (medium confidence: only PBDB gives this; nothing contradicts it).\n- Type species: Dacentrurus armatus (medium confidence: only PBDB gives this; nothing contradicts it).\n- Age, as published by the Paleobiology Database: Kimmeridgian to Barremian, 154.8–121.4 million years ago (high confidence: PBDB and NHM agree).\n- Age, Omnisaura's own calculation (not a published figure): 154.8–137.05 million years ago (medium confidence: Omnisaura's calculation from 26 confirmed PBDB records).\n- Fossils found in: United Kingdom (high: NHM and PBDB both record it); Spain (medium: only PBDB records it (11 records)); France (medium: only PBDB records it (3 records)); Portugal (medium: only PBDB records it (12 records)).\n- Rock formations: Kimmeridge Clay Formation (high: NHM and PBDB both record it); Alcobaça (medium: only PBDB records it (2 records)); Argiles d'Octeville (medium: only PBDB records it (2 records)); Freixial (medium: only PBDB records it (2 records)); Lourinhã (medium: only PBDB records it (6 records)); Villar del Arzobispo (medium: only PBDB records it (10 records)); Piedrahita de Muñó (low: only one PBDB record); Praia da Amoreira-Porto Novo (low: only one PBDB record).\n- Original description: F. A. Lucas (1902). Paleontological notes. The generic name Omosaurus. A new generic name for Stegosaurus marshi. Science, new series 16(402): 435. (medium confidence: only PBDB gives this; its author and year match the naming authority (Lucas 1902)).\n- Diet, inferred by PBDB for the group: herbivore (medium confidence: only PBDB gives this, and it infers it for the whole of Ornithischia, 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, gregarious (low confidence: PBDB infers this way of life for the whole of Ornithischia; behaviour is rarely known for one genus).\n\nNot known or disputed:\n- Authority: sources disagree (PBDB says Lucas 1902; Wikidata says Richard Owen, 1875). Awaiting an Omnisaura editor.\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- 2 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.
