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.
Dicraeosauridae is a family of diplodocoid sauropods who are the sister group to Diplodocidae.Dicraeosaurids are a part of the Flagellicaudata, along with Diplodocidae.. Dicraeosauridae includes genera such as Amargasaurus, Suuwassea, Dicraeosaurus, and Brachytrach
Amargatitanis and Amargasaurus probably fed above ground level at heights of up to 2.7 meters (8.9 ft), as evidenced by the anatomy of their neck and inner ear. Rebbachisaurids like Zapalasaurus presumably fed at ground-level, while basal Titanosauriforms exploited food sources at higher levels.
Sauropoda (/ s ɔː ˈ r ɒ p ə d ə /), whose members are known as sauropods (/ ˈ s ɔːr ə p ɒ d z /; [1] [2] from sauro-+ -pod, 'lizard-footed'), is a clade of saurischian ('lizard-hipped') dinosaurs.
Mounted skeletons of Tyrannosaurus (left) and Apatosaurus (right) at the AMNH. Dinosaurs are a diverse group of reptiles of the clade Dinosauria. 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.
Amargasaurus: 1991 La Amarga Formation (Early Cretaceous, Barremian to Aptian) Argentina: Possessed two parallel rows of backward-pointing spines on its neck that may have been covered by keratin sheaths [3] or a skin sail [4] Amargatitanis: 2007 La Amarga Formation (Early Cretaceous, Barremian to Aptian) Argentina
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.
Speculative life restoration with body based on the related Amargasaurus. Bajadasaurus is classified as a member of the Dicraeosauridae, a family of sauropod dinosaurs. As with all sauropods, dicraeosaurids were large, four-legged herbivores with a long neck and tail and a relatively tiny head.
