Diagnosis
ReferenceDiagnosis
L. Salgado and R. A. Coria 2009Large titanosaurian sauropod characterized by the following autapomorphies: 1) posterior
dorsal vertebrae bearing paired, short spinal laminae, nearly parallel to the prespinal lamina; 2) well-developed anterior spinodiapophyseal laminae in posterior dorsal vertebrae; 3) anterior spinodiapophyseal laminae divided into at least two, and up to three, branches in posteriormost dorsal vertebrae; 4) aliform processes with broad, planar and rugose laterodorsal surfaces; 5) portion of neural spine distal to the aliform process is longer than the portion of the spine that is proximal to the aliform process, at least in the posterior dorsals.
