The cervical neural arch is a complex bone adorned with nine laminae (plate-like ridges between various regions) and twelve fossae (deep pits between laminae).
The neural spine is tall, rising a short distance before bending backwards at a 30 degree angle.
The diapophyses (rib facets) are vertically extended and project laterally, though not very far.
The rear edge of the postzygapophyses (rear articular processes) are thin and dip downwards, though they do not converge and instead their bases are separated by a small, U-shaped gap.
Various other archosaurs have a similar postzygapophyseal projection, known as a hyposphene, though they differ from Carnufex in that their postzygapophyses converge at the base.
Few early pseudosuchians preserve enough of the atlas to properly compare with the crescent-shaped atlantal intercentrum of Carnufex.

The dorsal neural arch is similar to that of the cervical, with a few differences.
The diapophyses are much shorter and the zygapophyses are more level.
The dorsal is also less complex than the cervical, with only a few laminae and fossae.
These include a less prominent "hyposphene", possibly an intermediate stage between reptiles like Postosuchus, which has a prominent hyposphene in its dorsals, and crocodylomorphs, which lack such a structure entirely.
The neural spine is slightly expanded anteroposteriorly at its tip, like non-crocodylomorphs, but it does not have a spine table (lateral expansion).
An asymmetrical extension visible from the underside of the neural arch may be a pathological feature.
Preserved ribs are similar to those of other paracrocodylomorphs.

The humerus was short, with a constricted shaft.
It was more similar to Postosuchus than it was to other crocodylomorphs, as a result of several features.
These include a distal end approximately three times as wide as the shaft (as opposed to two times as wide), and the presence of an ectepicondylar groove and supinator process (which are not present in other crocodylomorphs).
There is also a unique characteristic present in Carnufex but absent in all of its relatives, that being a pronounced crest forming the rear edge of the ectepicondylar groove.
