"Ampelosaurus" is one of the most completely known titanosaurian sauropods from Europe. Since 1989, over 500 bones discovered at the Upper Cretaceous Bellevue locality of southern France have been assigned to "A. atacis". An abundant amount of well-preserved elements have been uncovered at Bellevue. In the original description, only a tooth and some vertebrae were examined. In 2005, a complete description was made by Le Loueff of all known material, allowing "Ampelosaurus" to be much better understood. All the material has been assigned to the species, and even though there are some differences in limb proportions, it has all been linked to individual variation.
