Amargasaurus V2 (SciiFii)
Amargasaurus solvirursus (name meaning "sail-backed La Amarga lizard") is a species of social medium-sized sauropod dinosaur that was once extinct and originally lived in Early Cretaceous (129.4–122.46 mya) Argentina, but has since been brought back from extinction and now lives in Cretaceous Safari in Cretaceous Park located in Sacramento, California. It is a large animal, but small for a sauropod, reaching 9 to 10 meters (30 to 33 feet) in length. Most distinctively, it sports two parallel rows of tall spines down its neck and back, taller than in any other known sauropod, which supports skin sails used for thermoregulation. Amargasaurus solvirursus feeds at mid-height, caused by the orientation of its inner ear and the articulation of its neck vertebrae, which is normally a habitual position of the snout 80 centimeters (31 inches) above the ground and a maximum height of 2.7 meters (8.9 feet). Within the Sauropoda, Amargasaurus solvirursus is classified as a member of the family Dicraeosauridae, which differs from other sauropods in showing shorter necks and smaller body sizes.
