Amargasaurus was small for a sauropod and its neck was also proportionally short as far as sauropod standards go. The feature that makes Amargasaurus' stand out from other sauropods are the extremely tall, upward projecting spines on the neck. These neural spines were forked along their length, forming a double row. It had a broad snout equipped with pencil-like teeth. There are a variety of ideas about the function of the spines, as well as the possibility of sails between the spines, including defense, communication (for mating purposes or for simple species recognition), or temperature regulation. Though recent thinking tends to think the spines had no skin in between.
