Diagnoza

Large, massive marginals with one or two cupules, excavated at their centre, with weakly developed tubercles. Extremely numerous (up to 20) facet canals are well marked on the ventral side and open into a crown. Kidney−shaped elevated crown with complicated, meandering system of apertures.

Porównanie

The ossicles are quite unlike any species recognised so far. The massive and large frontal plates from the assemblage most probably belong here.
