Diagnosis
ReferenceDiagnosis
J. E. Powell 2003A huge-sized titanosaurid. Stout humerous with broad proximal end that has a straight upper edge (margin) perpendicular to the long axis of the bone. Pectoral muscle insertion area far more prominent and projected forward and medially. Ulna with extremely robust proximal end showing prominent edges delimiting markedly concave facets. Stout metacarpals approximately one-third the length of the humerus.
