|
70-66 Ma | Ojo Alamo Formation, New Mexico, USA
North Horn Formation, Utah, USA
|
An opisthocoelicaudiine saltasaurid and one of the largest known North American dinosaurs. | |
|
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. | |
|
66 Ma | Udurchukan Formation, Russia | A dubious somphospondyl known from few remains. Some of the originally described remains actually belong to a hadrosaur. | |
|
70-66 Ma | Pab Formation, Pakistan | A titanosaur known a partial skull and several vertebrae. | |
|
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. | |
|
95-70 Ma, Cenomanian to Maastrichtian | Argentina | A little-known titanosaur known from a single maxilla. | |
|
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. | |
|
70 Ma | Brazil | An aeolosaurid titanosaur. | |
|
99.7-70.6 Ma, Cenomanian to Maastrichtian | Huiquanpu Formation, Shanxi, China | A mid-sized titanosaur, closely related to Tangvayosaurus. | |
|
70-66 Ma | Grès à Reptiles Formation, Provence-Alpes-Cote d'Azur, France | A titanosaurid with proportionally robust legs. Notable for having referred eggs. | |
|
70 Ma | Lameta Formation, Maharashtra, India | An antarctosaurid with a short, vertically directed neck and long forelimbs, considerably different from other sauropods. | |
|
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. | |
|
70-66 Ma | Pab Formation, Pakistan | A titanosaur closely related to Pakisaurus, known only from a tail vertebra. | |
|
71 Ma | Allen Formation, Neuquén Province, Argentina | A saltasaurine saltasaurid that, due to the presence of armor, was first thought to be an ankylosaur. | |
|
70-66 Ma | Sanpetru Formation, Hunedoara County, Romania | A nemegtosaurid and one of the smallest species of sauropod, measuring only six meters in length. | |
|
70-66 Ma | Pab Formation, Pakistan | A titanosaur closely related to Balochisaurus, known from a partial skeleton. | |
|
70 Ma | Nemegt Formation, Omnogovi Province, Mongolia | A nemegtosaurid with a long, diplodocoid-like skull with pencil-shaped teeth. | |
|
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. | |
|
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. | |
|
70-66 Ma | Pab Formation, Pakistan | A titanosaur known only from a few vertebrae. | |
|
Hunedoara County, Romania | A titanosaur known from a partial skeleton. | ||
|
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. | |
|
70-66 Ma | Maevarano Formation, Mahajanga Province, Madagascar | A fairly modestly-sized nemegtosaurid, likely around 15 meters (49 ft) in length. | |
|
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. | |
|
70-66 Ma | Pab Formation, Pakistan | A titanosaur closely related to Pakisaurus and Khetranisaurus. | |
|
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. | |
|
67 Ma | Marilia Formation, Brazil | A little-known titanosaur known from few bones. | |
|
70-66 Ma | Maevarano Formation, Mahajanga Province, Madagascar | A rare titanosaur, identified from a braincase. It is most similar to the Indian Jainosaurus. |
