The prezygapophyse extends beyond the centrum with a mediodorsally oriented facet. Posterior to the prezygapophyse and lateral to the neural canal there is a deep and oval centroprezygapohyseal fossa (

The extension of this ridge, as well as the centropostzygapophyseal lamina are not visible due to the break of the postzygapophysis. Yet it is possible that this ridge represents the epipostzygapophyseal lamina. In posterior view, the spinopostzygapohyseal fossa opens ventrally into the neural canal (

Only the centrum of the vertebra is present. It is anteriorly eroded as well as on the posterodorsal left side. A large opening is present on the left side of the anterior face but this seems artificial. The dorsal fracture is below most of the neural canal (except for anterior remains) as well as below the neurocentral suture, which is not visible.

) and considered as an autapomorphy of the former. The neurocentral suture is still visible above the pleurocentral depression. Eroded but visible anteriorly, the right parapophysis is astride slightly above the neurocentral suture. This character is found on most dorsal vertebrae; therefore, a more precise positioning is not possible. Based on the position of the parapophysis, this vertebra is interpreted as a sixth or more posterior dorsal vertebra.
