Sauropod dinosaur material excavated from one quarry in the Lower Cretaceous Hekou Group of the Lanzhou Basin, Gansu Province in 2004 pertain to a single, new taxon . Unique features of its sacrum, including an extremely low neural spine with a remarkably transversely expanded distal end, support the attribution of this material to a new genus and species of sauropod, Huanghetitan liujiaxiaensis gen. et sp. nov. Cladistic analysis strongly supports Huanghetitan as a basal member of the Titanosauriformes.
