The neural spine is distinctly reduced in height, occupying one-third the length of the neural arch, and beginning far behind the posterior border of the zygosphenal articular facets. The dorsal portion of the spine, in particular of its anterior half, is strongly thickened. The lateral foramina are clearly visible. The paradiapophyses are stout, somewhat higher than long, weakly divided into para- and diapophyseal portions. The prezygapophyseal buttresses (between the paradiapophyses and prezygapophyseal processes) are developed into prominent, anteriorly facing tubercles. The subcentral ridges are indistinct.

However, it cannot be interpreted as the last trunk vertebra because it is relatively distinctly longer than the cloacal vertebra (see below). The haemal keel, rounded in cross-section and posteroventrally developing into an obtuse tip, can be interpreted rather as a short hypapophysis (as typical of the end of the trunk portion of the column in booids and various other snakes).

In having a low and posteriorly located neural spine, it resembles the preceding vertebrae from the trunk portion of the column. The hypapophysis is reduced to a distinct though small bulge. Based on its similarities to the anterior caudal vertebrae (see below) rather than to those from the posterior trunk region as well as on the reduction of the hypapophysis, the vertebra is interpreted as originating from the posterior rather than anterior cloacal portion of the column.

Apart from this difference, however, the anterior caudals closely resemble the cloacal vertebra, among others in having a short and posteriorly located neural spine. The spines of the caudal vertebrae are, however, relatively higher than those of the trunk vertebrae and devoid of ‘T’-like thickening on their dorsal edges.</paragraph>

). Both structures have the same shape, when seen in lateral aspect. Another vertebra carries an ‘intermediate’ subcentral structure, namely a hypapophysis slightly forked distally; this vertebra is interpreted as coming from the transition between anterior and middle regions of the caudal portion of the column.
