  "summary": "Omnisaura summary: Lambeosaurus, Parks 1923\n\n- Named by: Parks 1923 (high confidence: PBDB and Wikidata agree).\n- Family: Hadrosauridae (high confidence: PBDB and NHM agree).\n- Order: Ornithischia (medium confidence: only NHM gives this; nothing contradicts it).\n- Parent group: Corythosaurini (medium confidence: only PBDB gives this; nothing contradicts it).\n- Age, as published by the Paleobiology Database: Campanian, 83.6–72.2 million years ago (medium confidence: only PBDB gives this; nothing contradicts it).\n- Age, Omnisaura's own calculation (not a published figure): 83.6–72.2 million years ago (medium confidence: Omnisaura's calculation from 19 confirmed PBDB records).\n- Fossils found in: Canada (medium: only PBDB records it (19 records)).\n- Rock formations: Dinosaur Park (medium: only PBDB records it (15 records)); Oldman (medium: only PBDB records it (3 records)).\n- Original description: W. A. Parks (1923). Corythosaurus intermedius, a new species of trachodont dinosaur. University of Toronto Studies, Geology Series 15: 1–57. (high confidence: PBDB gives this publication for the name; its author and year match the naming authority (Parks 1923), on which PBDB and Wikidata agree).\n- Diet, inferred by PBDB for the group: herbivore (medium confidence: only PBDB gives this, and it infers it for the whole of Ornithopoda, 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- 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)."
