| X. Zhang et al. 2009 | A medium-sized titanosauriform sauropod dinosaur bearing the following combined characters: somphosponylous presacral vertebrae, similar to those of Euhelopus and other titanosaurs; the neural spine of the mid-dorsal vertebra is very short, with weak post-spinal laminae and no prespinal laminaa; the transverse process is supported by four laminae; the dorsal portion of the anterior centroparapophyseal laminae if bifurcated, with a small branch extending to the ventral surface of the prezygapophysis; posterior centrodiapophyseal lamina is thin, nearly vertical, and not forked at its ventral end; the popzygodiapophyseal lamina is undeveloped; posterior dorsal neural arches with prezygapophyses; anterior dorsal ribs are apneumatic, similar to those of basal macronarians; and the anterior caudal vertebrae is much shorter than wide and amphicoelous. |
