Based on a partial postcranial skeleton. The holotype specimen consists of the left ilium, left pubis, anterior caudals, most of the dorsal ribs and distal end of the left femur. Fusuisaurus zhaoi is diagnosed by a unique combination of character states among the known sauropods. It displays several synapomorphies of Titanosauriformes but lacks many derived features seen in other titanosauriforms, suggesting that the new taxon represents the basalmost known titanosauriform and providing new evidence that Titanosauriformes originated from Asia. A size comparison suggests that Fusuisaurus zhaoi is among the largest Early Cretaceous sauropods,providing an important addition to the Early Cretaceous Chinese sauropod diversity.

NHMG6729 (Natural History Museum og Guangxi); a relative complete left ilium, a complete left pubis, 3 incomplete articulated anterior caudals, most of dorsal ribs and distal end of the left femur are preserved.
A large sauropod distinguished from all other taxa in having a combination of the following character states: anterior dorsal ribs non-pneumatic, presence of a prominent, pointed anteroventral process of the ilium, the preacetabular blade strongly expanded dorsoventrally, posterior margin of the ilium notched, and transverse process of the anterior caudal vertebrae dorsoventrally flattened.
