Fossil representation: Based upon an almost complete and semi articulated post cranial skeleton.

       Named very early in the twenty-first century,‭ ‬Huabeisaurus has fast become one of the big names amongst the Asian sauropods.‭ ‬This is mostly because that so far Huabeisaurus is one of the most complete sauropods to come out of Asia,‭ ‬and this in turn has actually caused many palaeontologists to question the family classification of many Asian sauropods.‭ ‬This is because the three main groups of Asian sauropods are usually classed between the Nemegtosauridae,‭ ‬Opisthocoelicaudinae and Euhelopodidae‭ (‬named after Nemegtosaurus,‭ ‬Opisthocoelicaudia and Euhelopus respectively‭)‬,‭ ‬and the former of these,‭ ‬Euhelopodidae is usually the family group that Huabeisaurus is assigned to.
       The problem between these groups however is that they were established when there were relatively few Asian known,‭ ‬but now stretching from Thailand,‭ ‬across China and over to Japan,‭ ‬there are now many Asian genera of sauropods known,‭ ‬and the number continues to rise.‭ ‬One bit of knowledge gleaned from all this discoveries as that the classic family groups of Asian sauropods are not as distinctive between one another as once thought,‭ ‬and that it is extremely likely that in the future some of the genera assigned to these groups will be split to form new groups.‭ ‬In fact when the description of Huabeisaurus was first published,‭ ‬the original describers suggested that Huabeisaurus should be combined with the genus Tangvayosaurus to establish a new group of Asian sauropods named the Huabeisauridae.‭ ‬Although not taken up by other palaeontologists,‭ ‬the new family was again proposed in a‭ ‬2013‭ ‬osteology report on Huabeisaurus.
       Huabeisaurus appears to have been a mid-sized sauropod dinosaur,‭ ‬and estimated to have attained a‭ ‬length of about twenty meters.‭ ‬However,‭ ‬lack of complete bone fusion on the vertebrae of the holotype indicates that the type specimen was not yet fully grown at the time of death.‭ ‬It’s certain that individuals of Huabeisaurus could have grown larger than this,‭ ‬but by how much is unknown,‭ ‬but probably somewhere between twenty and twenty-five meters depending upon the individual.‭ ‬Only the discovery of more individuals of Huabeisaurus however will allow for a confirmed upper size for the genus.
       Huabeisaurus has been confirmed as living alongside dinosaurs along the lines of ankylosaurs,‭ ‬hadrosaurs and theropods,‭ ‬though many of the fossils of these from the same formation as Huabeisaurus are usually too indeterminate to identify a genus.
