Fendusaurus is known from five specimens of skeletal elements.[1] The specimens include a holotype, FGM998GF13-II,[2] that includes a skull, and cannot be assigned to cf. Ammosaurus.[1] Other specimens are also assigned to Fendusaurus, FGM998GF13-I, FGM998GF13-III, FGM998GF69, FGM998GF9, and FGM998GF18, all found by a crew from the Princeton University.[2] All the specimens include femora and coracoids, and although they each share slightly different features, the differences are credited to intra-specific variation. The femora and coracoids also help identify different individuals, and Timothy J. Fedak, the described of the specimens, found that each block represented about one individual.[1]
