Fusuisaurus (meaning “Fusui lizard” from the name of the county where it was discovered) is a genus of sauropod dinosaur from the Early Cretaceous of China. Fragmentary postcranial remains of this animal have been discovered in 2001 in the Napai Formation of Guangxi, China and consist of the left ilium, left pubis, anterior caudals, most of the dorsal ribs and distal end of the left femur. This sauropod has been described as a basal titanosauriform.
The type species is F. zhaoi, named in honour of Chinese paleontologist Zhao Xijin.
Fusuisaurus was very basic in the group of Titanosauriformes and was seen as an indication that the clade has its origin in Asia. It is considered one of the largest dinosaurs of the Cretaceous.
This dinosaur is known for a very incomplete skeleton, including ilium and pubis claims, caudal vertebrae, ribs and dorsal part of the left femur. The remains, although fragmentary, are evidence of the existence of one of the largest sauropods of the Cretaceous, comparable in size to the American Sauroposeidon (about 30 meters long). The fossils suggest that this dinosaur was a representative of a group of primitive titanosauriforms, which includes most of the known Cretaceous sauropods. The name comes from Fusui County, where the fossils were found, while the specific name honors the Chinese paleontologist Zhao Xijin.
