Amargasaurus (/ ə ˌ m ɑːr ɡ ə ˈ s ɔː r ə s /; "La Amarga lizard") is a genus of sauropod dinosaur from the Early Cretaceous epoch (129.4–122.46 mya) of what is now Argentina.The only known skeleton was discovered in 1984 and is virtually complete, including a fragmentary skull, making Amargasaurus one of the best-known sauropods of its epoch.
The group likely first diverged from the diplodocids in the middle Jurassic in North America and subsequently dispersed into Gondwana, with the most diversity in East Africa and South America. [6] Amargasaurus was the latest surviving dicraeosaurid genus, living into the Early Cretaceous period.
Pilmatueia faundezi fossils have been found in the Mulichinco Formation of Argentina.Known material includes the holotype, MLL Pv-005, a posterior dorsal vertebra; [1] the paratype MLL-Pv-002, a posterior cervical vertebra; MLL-Pv-010, a partial skeleton including cervical vertebrae, dorsal vertebrae, ribs, a caudal vertebra, and incomplete scapulae; [4] and other isolated vertebrae.

Eusauropoda (meaning "True Lizard Foot") is a derived clade of sauropod dinosaurs.Eusauropods represent the node-based group that includes all descendant sauropods starting with the basal eusauropods of Shunosaurus, and possibly Barapasaurus, and Amygdalodon, but excluding Vulcanodon and Rhoetosaurus.

They first appeared during the Triassic period, between 243 and 233.23 million years ago, although the exact origin and timing of the evolution of dinosaurs is the subject of active research. They became the dominant terrestrial vertebrates after the Triassic–Jurassic extinction event 201.3 million years ago; their dominance continued ...
Many gigantic forms existed in the Late Jurassic (specifically Kimmeridgian), such as the turiasaur Turiasaurus, the mamenchisaurids Mamenchisaurus and Xinjiangtitan, the diplodocoids Maraapunisaurus, Diplodocus, Apatosaurus, Supersaurus and Barosaurus, the camarasaurid Camarasaurus, and the brachiosaurids Brachiosaurus and Giraffatitan.
Diplodocoidea is a superfamily of sauropod dinosaurs, which included some of the longest animals of all time, including slender giants like Supersaurus, Diplodocus, Apatosaurus, and Amphicoelias.
Sauroposeidon (/ ˌ s ɔːr oʊ p oʊ ˈ s aɪ d ən / SOR-o-po-SY-dən; meaning "lizard earthquake god", after the Greek god Poseidon [3] [4]) is a genus of sauropod dinosaur known from several incomplete specimens including a bone bed and fossilized trackways that have been found in the U.S. states of Oklahoma, Wyoming, and Texas.
