Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| J. D. Gardner 2000 | Genus of albanerpetontid differing from Albanerpeton inhaving fused frontals more derived in bearing bulbous-shaped internasal process and more primitive in retaining hourglass- or bell-shaped outline. Differs further from Albanerpeton in another six frontal character states ofuncertain polarities: ratio of midline length to width across posterior edge betweenlateral edges of ventrolateral crests greater than about 1.2; intemasal process ventrolaterally has facet for dorsally overlapping medial edge of nasal; anterolateral process a poorly differentiated, broadly rounded shoulder; dorsal and ventral edges of slot for receipt of prefrontal not excavated mediallv: anterior end of orbital margin located anterior to anteroposterior midpoint of frontals; and orbital margin deeply concave in dorsal or ventral outline, occasionally deflected posterolaterally near posterior end. | |
| G. J. McGowan 2002 | An albanerpetontid in which the frontal differs from that of Albanerpetonin having a wide bulbous, almost circular anterior process; orbital margins curved and longer than half the anterior-posterior frontal length (>60%). |
