They were the largest herbivores in their environment, and quickly reached (6 to 10 meters long). All prosauropods had a long neck and small head, forelimbs shorter than the hindlimbs, and a very large thumb claw for defense. They were originally thought to be the ancestors of the sauropods, but are now considered by some as a parallel lineage.
