Porównanie

The description by Dybczyński (1913) suggests that this may be an early member of the Armatites lineage, as indicated by flat flanks and semicircular appearance of flank lobes. Unfortunately, his description and illustrations remain the only source of data on this species. The illustrated specimen is a juvenile and its generalized appearance (especially the rounded venter) may be partly due to the early ontogenetic stage. Both its morphology and probable stratigraphic origin (C. marginifera Zone) suggest its ancestral position in respect to other species of Armatites.
