is well-represented in limestone from the Sosnogorsk locality by some articulated head shields and ventral walls of the trunk armour, some articulated proximal segments of the pectoral fin, as well as by numerous disarticulated plates of the head and trunk shields, and pectoral appendage. Most are from individuals of moderate size; however, there are remains from a very large, as well as from very small individuals. The plates are usually slightly flattened, sometimes deformed and bear cracks, most probably due to compaction of the fossil-bearing limestone.

) shows their cast. The shape of the plate is rhombic with a slightly convex anterior and an almost straight posterior margin. The lateral margin is slightly concave, forming a prominent postero-lateral corner. The mesial margin is oblique therefore the split between pair of suborbital plates widens posteriorly. The ventral margin seems to bear rather small tubercles showing weakly defined denticulation. The visceral surface is dominated by a pronounced transverse ridge, which begins near the dorso-mesial corner, and extends obliquely, towards the middle of the lateral edge of the plate. It forms a posteriorly oriented convex curve. The height of this ridge varies: large close to the mesial margin and becoming lower laterally. The morphology of the visceral surface of
