Completely reduced cusp , strongly thickened processes parallely arranged, leaving only a narrow fissure in between. Basal cavity restricted only to the distal margins of the processes.

Porównanie

This is a typically Late Cambrian species which has however been repeatedly reported also from the early and even middle Ordovician. It seems highly unlikely that the specimens from the Mójcza Limestone had been reworked
from Cambrian strata because the Cambrian in the Kielce area is developed only in a coarse clastic facies. The species is more likely a survivor of its long ranging lineage.
