Fossil remains for this Dinosaur have been found in Argentina, South America

A medium-sized member of the Sauropod family, Amargasaurus had a short neck with a double row of tall spines on top. The purpose of these spines is not clear, but they may have supported a fleshy sail, or may have been covered in a hard, horn-like sheath.

The splitting of the neural spines is common in the Diplodocoidea, but reached a most extreme form in the Amargasaurus, developing into spines 50 cm (1.5 Feet) long. Amargasaurus had peg-like teeth, and could not chew its food, so it swallowed "gizzard stones" that aided in the digestive process.

Amargasaurus is known from a single set of fossils, found without a tail, so its size is not certain.
