Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| H. Zaher et al. 2011 | An advanced titanosaurian diagnosed by the following autapomorphies: hook-shaped posteroventral process of the quadratojugal; anterior process of the jugal tapering and forming most of the ventral margin of the antorbital fenestra; anterolateral tip of the pterygoid contacts the medial surface of the ectopterygoid. The new taxon is also diagnosed by the following unique combination of characters: deep fossa on the lateral surface of the maxilla between the antorbital fenestra and the subnarial foramen; elongated middle cervical vertebrae; posterior dorsal vertebrae with well-developed prespinal lamina and absence of hyposphene-hypantrum; deep fossae located below intraprezygapohyseal lamina; crescentric-shaped sternal plate; proximodistally long coracoid; elongated ulna and distally expanded radius. |
