Like most sauropods, it would have had a long neck and tail but it also carried armor in the form of osteoderms. Over 500 bones have been assigned to "Ampelosaurus" and all but the braincase (assigned to "A." sp.) has been assigned to "A. atacis". They are assigned to the same species because all the differences in the limb proportions have been linked to individual variation. "A. atacis" is known from a few, well-preserved teeth and some cranial material. A right scapula was discovered associated with a coracoid. The blade of the scapula, contrary to most titanosaurs, is triangular. The blade narrows at one end instead of showing an expansion like most other genera. "A. atacis" is also known from a pubis about long and an ilium. Aside from that, it is known from a partial forelimb, and many femora.
