Amargasaurus cazuai

…is a species of short-necked dricarosaurid sauropod dinosaur from early Cretaceous of what is now South America. A.cazuai was small as far as sauropods go, as it was “only” around 10 meters long. Armagasaurus is noted for its upward projecting vertebral spines on its neck and back, their exact function is unknown but they might have supported sails that could have been used for defense, communication, mating, or temperature regulation. Like other sauropos Amargasaurus was a herbivore and fed on plant matter.
