The original description of the species noted strong similarities between the osteology of "Huabeisaurus" and other Cretaceous East Asian sauropods, and in general, previous studies have pointed to some East Asian Cretaceous sauropod (like "Nemegtosaurus" and "Phuwiangosaurus") as the sister taxon of "Huabeisaurus". Since 2000, the year of the original description of "Huabeisaurus", 17 new sauropod species have been erected from the Cretaceous of East Asia. Many authors have noted similarities among Cretaceous East Asian sauropods, often suggesting that several of these taxa belong to a clade grounded on a genus with well-known anatomy (like Nemegtosauridae, Opisthocoelicaudinae, and Euhelopodidae). Cladistic support was recently presented for a Euhelopodidae that consisted of exclusively Cretaceous-aged members, in contrast with traditional studies and early cladistic analyses that placed the existence of a Euhelopodidae with Jurassic forms. Both earlier and later analyses suggest some degree of endemism in East Asia, though its temporal duration remains uncertain. On a broader scale, an interesting evolutionary pattern has been recognized wherein all pre-Cretaceous Jurassic Asian sauropods lie outside of Neosauropoda, whereas all Cretaceous Asian sauropods are titanosauriforms. Refining and explaining these paleobiogeographic patterns through time rests on detailed comparisons and comprehensive phylogenetic studies including East Asian sauropods, which are currently lacking.
