Since its original description, several specimens have been referred to "Hypselosaurus". One of these, originally described in 1957 by Albert de Lapparent, includes a caudal vertebra, as well as another vertebra described in 1960 by Bataller. In 1993, a review of European sauropods stated that "Hypselosaurus" was a "nomen dubium", and that its holotype could not be verifiably distinguished from other sauropods in the same, and many other, regions. Based on this, the material that was referred to "Hypselosaurus" by several other authors would have to be considered an intermediate titanosaur.
