Amargasaurus is an extinct genus of sauropod dinosaur from the Early Cretaceous period and measuring up to 10 meters (33 feet) long. A distinctive feature of this dinosaur are the a pair of parallel rows of tall spines down its neck and back, taller than in any other known sauropod. It is an example of Convergent Evolution; with thyreophoran-like, almost spinosaurian dorsal, cervical, and caudal vertebral spines.
In 2022, recent analyses have shown that Amargasaurus is unlikely to have had sails in life, due to it restricting its neck movement.

Behind the scenes
Amargasaurus appears in concept art for the 2015 Jurassic Park arcade game but does not appear in the final game itself.
Amargasaurus DNA might have been used in the creation of the Unidentified Therizinosaur Hybrid seen on a computer screen in Jurassic World. It can be speculated since the hybrid appears to have spines similar to the ones in the sauropod.
