Diagnosis
ReferenceDiagnosis
J. E. Powell 2003Centra of the dorsal vertebrae relatively large, very broad and depressed. Pleurocoels very large and deep as in the other known titanosaurids. Neural spines of the posterior dorsals anteroposteriorly compressed, with prespinal laminae thickened and well developed, forked at the lower part, forming the spinal-prezygapophyseal lamina. Accessory articulations are present but distinct from the hyposphene-hypantrum structures. The diapophysis without a flat surface at the dorsal end.
