The neurocentral sutures between the neural arch and the centrum can be recognized in both vertebrae (Fig.
The neurocentral suture can be seen in the left side of this vertebra, under the transverse process.
The transverse processes are high but not prominent, reaching the pedicels of the neural arch and the neurocentral suture.

They are anteroventrally to dorsocaudally oval in outline, forming a strong prominence immediately beneath the neurocentral suture, as described in Andrews (1913).
In addition, the neurocentral sutures are completely obliterated, as in mature crocodylians (Brochu, 1996; Herrera et al.

It can be distinguished by its slightly longer diapophyses, which are dorsally placed with respect to the neural canal, or the parapophyses, which are less marked, dorsally placed and closer to the neurocentral
suture (Mook, 1921; Wu et al.
The neural arch is broken above the neurocentral suture, and two stout pedicles remain fused to the centrum.
As in the other specimens, the neurocentral sutural fusion between the centrum and neural arch is complete.
