Compared to the other zatracheidids, it has the proportionately widest skull and the smallest internarial fontanelle, which only slightly divides the nasals. it also lacks posteriorly extensive tabular horns and postparietal horns. It is also the only zatracheidid with definitively known postcranial material.

Based on the changes to the skeleton and the distribution of size classes within the locality, Witzmann & Schoch (2006) suggested that
