Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| J. E. Powell 1992 | Skull with supratemporal fenestra more reduced than in Antarctosaurus, closed dorsally by fusion of the parietal and frontal: basisphenoid complex of triangular shape in ventral view, with a transversely narrow base and a pronounced sagittal crest; fenestra ovalis open to the passage of nerves IX-XI, basipterygoids joined proximally; basal tubera of the basioccipital are fused.
The cervical vertebrae are relatively shorter and broader than those of the known titanosaurs. Dorsal vertebrae centra lack ventral keels. The neural spines are very thick and round. Dorsal surface of the diapophysis is flat distally. The sacrum has six fused vertebrae with the articular surfaces convex anteriorly and posteriorly. The first caudal is procoelous. The broad neural spine is compressed anteroposteriorly, and also is somewhat inclined toward the back in the anterior caudals. The scapula shows a medial prominence close to the anterodorsal edge. The long bones are relatively short and sturdy. The metacarpals are shorter than in Antarctosaurus, Argyrosaurus and the titanosaurs. | |
| J. E. Powell 2003 | Skull with the upper temporal aperture far more reduced than in Antarctosaurus, dorsally closed by the coalescence of the parietal and the frontal, complete basisphenoid with a triangular shape in the central view, the base is transversally narrow with a pronounced sagittal crest, the fenestra ovalis opens for the passage of the IX–XI cranial nerves, the basipterygoid processes are united at their proximal ends. Cervical vertebrae are relatively shorter and broader than in the known titanosaurs. The centra of the dorsal vertebrae are without 'keels'. Neural spines are distally extremely stout and rounded. Diapophyses with a flat dorsal surface at their distal end. Sacrum with six fused vertebrae, with convex anterior and posterior articulations. The first caudal vertebra is procoelous. The neural spine broad and anteroposteriorly compressed, inclined backwards in the first caudal vertebra. Scapula with a medial prominence close to the anterodorsal edge. Long bones relatively short and robust. Metacarpals much shorter than in Antarctosaurus and Argyrosaurus and those referred to Titanosaurus. Ilium with preacetabular lamina long and strongly curved outward. Intradermic ossicles, and dermal scutes. |
