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 it.
