The mandible of Bulbasaurus was largely similar to Aulacephalodon.
At the front of the mandible, the two toothless dentary bones fuse at the front to form a continuous beak with a sharp, pointed tip.
The somewhat convex front surface of this junction, or the dentary symphysis, is separated from the sides of the dentaries by sharp ridges, a condition also seen in Pelanomodon and Geikia but not seen in Aulacephalodon.
Overall, the dentary was tall and robust, the symphysis more so than the rest of the bone.
Located at the mid-height of the dentaries are the mandibular fenestrae, which are small and oval, and bordered on top by a dentary shelf that expands into a boss.
Asides from the skull, the other portions of Bulbasaurus have not been prepared in depth.
The ribs are gently curved and are bicipital in that they have two heads.
On the humerus, the deltopectoral crest was robust and strongly separated.
