Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| J. F. Bonaparte and R. A. Coria 1993 | Titanosaurs that possess the following associated characters: small pleurocoels located in the anterior region of an ovoid pleurocoelic depression; two or three deep triangular depressions in the lateral face of the neural arch; neural arch and neural spine of the dorsal vertebrae more high than in Titanosauridae; very developed hyposphene-hypantrum, in some genera with extra articular sides; middle and distal caudal vertebrae amphiplatyan with short prezygapophysial processes. (Translated by M. C. Lamanna.) | |
| J. F. Bonaparte 1996 | Titanosaurs showing the following combination of characters: dorsal vertebrae with small pleurocoels located in anterior part of a pleurocoelian, ovoid depression; two or three triangular, deep depressions on lateral side of neural arch; tall neural arch with elongate neural spine; well-developed hyposphene-hypanthrum; amphiplatian to slight opisthocoelian dorsal vertebrae; central caudal vertebrae (not known the proximal ones) amphiplatian with rather short prezygapophysial process. |
