STUDIED SAMPLES. — Three specimens ( MNHN.F. A32015 View Materials ) found among the Cyclophyllopsis cornutiformis paratypes arbitrarily numbered 1, 2 and 3 for the needs of this description (collections MNHN). GEOGRAPHIC AND STRATIGRAPHIC RANGES. — Pliensbachian of Jebel Bou Dahar ( Morocco).

DESCRIPTION

Solitary, cylindro-conical corallum subcircular to elliptic (quite distorted) in outline. Radial elements are straight, free septa or costosepta made of septal spines projecting at the inner edge of septa, providing a spiky aspect characteristic of the genus. Lateral faces are smooth. No real columella observed but an elongated fossa that defines a bilateral symmetry. Septal projections may produce a deep parietal papillose columella. Endotheca not observed. No synapticulae. Wall probably parathecal or septothecal. An epitheca s.l. wraps the corallite.

Calicular diameter: 7 to 17 mm – Number of septa: approximately 70 to 132 – Septal density: 5 to 8 per 2 mm – trabecular density: 5 to 7 per 2 mm.

REMARK

Many species assigned to Epismilia fit with our specimens with regards to their number of septa and diameter. However many of them are not documented enough in terms of septal structure and ornamentation. This genus for which many species have been created obviously needs a revision. This is the reason why we have chosen the open nomenclature in the present case.
