The Amargasaurus is a herbivorous sauropod dinosaur from the Early Cretaceous epoch of modern day Argentina. Its two parallel rows of tall spines down its neck and back are taller than in any other known sauropod, and while it was a large animal, it was short in length for a sauropod. Other physical features included a long tail and neck, a small head, and a barrel-shaped trunk that was supported by four column-like legs. It was discovered in February 1984 by Guillermo Rougier during an expedition led by an Argentine paleontologist, Jose Bonaparte.
The Amargasaurus had an overall length between 30’-33' (9.14-10 m), standing height of 7’-8.2’ (2.15-2.5 m), body width of 3.4’-4.4’ (1.05-1.35 m), and weight from 5,700-6,600 lb (2,585-2,994 kg). The typical lifespan of the Amargasaurus was between 25-35 years.
