Aeolosaurus
Like all sauropods, "Aeolosaurus" was a large, long-necked, quadrupedal herbivore. "A. rionegrinus" was roughly 14 meters long. "A. rionegrinus" was heavily-built for a titanosaur, with limb bones similar in robustness to those of "Saltasaurus", whereas "A. maximus" appears to have been more slender.
