|---|---|---|
| J. F. Bonaparte and R. A. Coria 1993 | Titanosaurs of great size with the following associated characters: opisthocoelous dorsal vertebrae provided with very developed hyposphene-hypantra, with extra articulations between them. Anterior dorsals with transversely wide and anteroposteriorly planar neural spines, endowed with robust prespinal laminae. Middle and posterior dorsals with low and wide vertebral bodies, with the ventral face almost planar, and with pleurocoels located in the anterior half of the body. Sacral vertebral bodies 2 to 5 very reduced. Dorsal ribs of tubular, cylindrical, and hollow structure. Bony macrocells in the sacrum and presacral vertebrae. Slender tibia with short cnemial crest.
