An isolated humerus, designated the paratype by Pang and Cheng, comes from a locality over 200 meters away from the type locality of "Huabeisaurus", in a fluvially deposited sandy conglomeratic layer in the lower member of the Huiquanpu Formation. This layer is roughly 90 m lower stratigraphically than the type horizon of "Huabeisaurus", which comes from the upper member of the Huiquanpu Formation. The humerus thus comes from a stratum representing a different and likely older depositional environment than that of "Huabeisaurus", and does not overlap anatomically with the holotypic skeleton, and so cannot currently be referred to that taxon. The horizon that yielded the humerus also contains hadrosaurid specimens referred to cf. "Shantungosaurus" sp. and indeterminate ankylosaurid material.
