Diagnoza

Emended diagnosis by Boczarowski, 2001:

Both distal and proximal margins of goniodonts almost straight V−shaped. The main denticle larger and broader than in remaining denticles. Lateral denticles numerous (26–44), becoming smaller and smaller. The tooth lamina slightly vaulted. The impressions of earlier generation teeth distinct.

Porównanie

The holotype of Cardioserra minima differs from the holotype of S. minima both in outline of goniodonts and development of teeth.
