Nine unique characters diagnose Bermanerpeton kinneyi. Many of these features are shared with branchiosaurids and larval "amphibamids," for example the character complex around the Y-shaped palatine. Otherwise, Bermanerpeton is clearly a dvinosaurian because of its anterior palatal fenestra, a shallow embayment/reduced otic notch and elongated interclavicle. Therefore, the "branchiosaurid lateral palate" was convergently evolved in larval branchiosaurids, "amphibamids" and dvinosaurians.

A new early adult specimen of M. huberi from the Kinney Brick Quarry brings new insights to the ontogenetic development of the Amphibamiformes Schoch, 2019. Larval M. huberi combines many features of the branchiosaurids and "amphibamids," but has predominantly branchiosaurid characters. Their unique character set includes the outline shape of the supratemporal, the smooth ventral basal plate of the parasphenoid with foramina for the internal carotid arteries, the branchial ossicles with a round basal plate and up to two very long, needle-like processes, a hyobranchial skeleton of eisfeldi-morphotype, and large, heavily ossified thoracic neural arches. Metamorphosis extensively changed these characters. The early adult M. huberi is fully "amphibamid," with characteristic features: narrow snout region with very narrow and elongated nasal and lacrimal, contact of post-and prefrontal, very wide skull with wide cheek region, narrow choana, elongated basal plate of parasphenoid, quadrate condyle closely associated with occipital condyle, ilium with very wide dorsal process, and probable terrestrial habitus indicated by elongated radius. M. huberi is the first "amphibamid," with a presacral count of 22 vertebrae, which was previously known from amphibamiforms only in branchiosaurids.
