Saltasaurus
  • Ampelosaurus atacis
70-66 Ma Marnes Rouges Inferieures Formation, France This nemegtosaurid had distinctive osteoderms with three different morphologies. It would have stretched up to about 15 meters (49 ft) from snout to tail.
  • Arkharavia heterocoelica
66 Ma Udurchukan Formation, Russia A dubious somphospondyl known from few remains. Some of the originally described remains actually belong to a hadrosaur.
  • Balochisaurus malkani
70-66 Ma Pab Formation, Pakistan A titanosaur known a partial skull and several vertebrae.
  • Bonatitan reigi
84-66 Ma, Santonian to Maastrichtian Argentina A saltasaurid known from a partial skeleton, including a braincase and caudal vertebrae. It may be a saltasaurine.
  • Campylodoniscus ameghinoi
95-70 Ma, Cenomanian to Maastrichtian Argentina A little-known titanosaur known from a single maxilla.
  • Dreadnoughtus schrani
84-66 Ma, Santonian to Maastrichtian Cerro Fortaleza Formation, Santa Cruz Province, Argentina A giant titanosaur, possessing the greatest mass of any land animal that can be calculated with reasonable certainty. It is known to be 26 meters (85 ft) long and 6 meters (20 ft) tall at the shoulder.
  • Gondwanatitan faustoi
70 Ma Brazil An aeolosaurid titanosaur.
  • Huabeisaurus allocotus
99.7-70.6 Ma, Cenomanian to Maastrichtian Huiquanpu Formation, Shanxi, China A mid-sized titanosaur, closely related to Tangvayosaurus.
  • Hypselosaurus priscus
70-66 Ma Grès à Reptiles Formation, Provence-Alpes-Cote d'Azur, France A titanosaurid with proportionally robust legs. Notable for having referred eggs.
  • Isisaurus colberti
70 Ma Lameta Formation, Maharashtra, India An antarctosaurid with a short, vertically directed neck and long forelimbs, considerably different from other sauropods.
  • Jainosaurus septentrionalis
68 Ma Lameta Formation, Madhya Pradesh, India A large titanosaur that would have measured around eighteen meters long and held its head six meters high.
  • Khetranisaurus barkhani
70-66 Ma Pab Formation, Pakistan A titanosaur closely related to Pakisaurus, known only from a tail vertebra.
  • Loricosaurus noricus
71 Ma Allen Formation, Neuquén Province, Argentina A saltasaurine saltasaurid that, due to the presence of armor, was first thought to be an ankylosaur.
  • Magyarosaurus dacus
70-66 Ma Sanpetru Formation, Hunedoara County, Romania A nemegtosaurid and one of the smallest species of sauropod, measuring only six meters in length.
  • Marisaurus jeffi
70-66 Ma Pab Formation, Pakistan A titanosaur closely related to Balochisaurus, known from a partial skeleton.
  • Nemegtosaurus mongoliensis
  • Nemegtosaurus pachi
70 Ma Nemegt Formation, Omnogovi Province, Mongolia A nemegtosaurid with a long, diplodocoid-like skull with pencil-shaped teeth.
  • Neuquensaurus australis
  • Neuquensaurus robustus
71 Ma Anacleto Formation, Neuquén Province, Argentina

Uruguay

A saltasaurine saltasaurid. A relatively small sauropod, it is one of the most completely known of Patagonian sauropods.
  • Opisthocoelocaudia skarzynskii
70 Ma Nemegt Formation, Omnogovi Province, Mongolia An opisthocoelicaudiine saltasaurid measuring over 11 m (36 ft) long. It is one of the best known sauropods from the Late Cretaceous.
  • Pakisaurus balochistani
70-66 Ma Pab Formation, Pakistan A titanosaur known only from a few vertebrae.
  • Paludititan nalatzensis
Hunedoara County, Romania A titanosaur known from a partial skeleton.
  • Quaesitosaurus orientalis
85-70 Ma, Santonian to Maastrichtian Barun Goyot Formation, Omnogovi Province, Mongolia A nemegtosaurid known only from a partial skull. It is possible that it is closely related to, if not a synonym of, Nemegtosaurus, which is also known only from cranial material.
  • Rapetosaurus krausei
70-66 Ma Maevarano Formation, Mahajanga Province, Madagascar A fairly modestly-sized nemegtosaurid, likely around 15 meters (49 ft) in length.
  • Saltasaurus loricatus
70 Ma Lecho Formation, Salta Province, Argentina

Uruguay

A well-known saltasaurine saltasaurid. Relatively small for a sauropod, it was the first genus of sauropod known to possess armor - in this case, bony plates embedded in its skin.
  • Sulaimanisaurus gingerichi
70-66 Ma Pab Formation, Pakistan A titanosaur closely related to Pakisaurus and Khetranisaurus.
  • Titanosaurus indicus
  • Titanosaurus blandfordi
70 Ma Lameta Formation, India A dubious titanosaurid. Traditionally it has bee treated as a "wastebin taxon" for poorly preserved titanosaur remains. Later discoveries have showed its unique traits are nondiagnostic in titanosaurs, and Titanosaurus is thus considered a nomen dubium by most paleontologists.
  • Uberabatitan ribeiroi
67 Ma Marilia Formation, Brazil A little-known titanosaur known from few bones.
  • Vahiny depereti
70-66 Ma Maevarano Formation, Mahajanga Province, Madagascar A rare titanosaur, identified from a braincase. It is most similar to the Indian Jainosaurus.
