Diagnosis
ReferenceDiagnosis
C. W. Wright and E.V. Wright 1940Bulbous marginal of great height, bilaterally symmetrical, with a profile like that of Pycinaster, ornamented with fine shallow spine-pits between small rugosities. The main articular faces are distinctly concave. The ossicles known were probably single prominent superomarginalia in the centre of each interradial arc.
