Xu, Z.-L. Tang, X.-L. Wang (1999). A therizinosauroid dinosaur with integumentary structures from China. Nature 399: 350–354. https://doi.org/10.1038/20670 (medium confidence: only PBDB gives this; its author and year match the naming authority (Xu et al. 1999)).\n- Diet, inferred by PBDB for the group: herbivore (medium confidence: only PBDB gives this, and it infers it for the whole of Therizinosauroidea, 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 (low confidence: PBDB infers this way of life for the whole of Therizinosauroidea; behaviour is rarely known for one genus).\n- Common names: ベイピアオサウルス, 北票龙 (medium confidence: only Wikidata gives this; nothing contradicts it).\n\nNot known or disputed:\n- Order: no source Omnisaura uses gives this.\n- Family: 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): Paleobiology Database (CC-BY-4.0); Wikidata (CC0-1.0)."
