STUDIED SAMPLE. — Holotype MNHN.F.R11648. GEOGRAPHIC AND STRATIGRAPHIC RANGES. — Pliensbachian of Jebel Bou Dahar ( Morocco) .
DESCRIPTION
Subcylindrical corallum, elliptical in outline, with convex calicular plateau showing a slightly depressed fossa. Radial elements are subcompact, straight or slightly curved, free or joined costosepta with a stylophyllid structure. We did not observed the pennulae described by Beauvais (1986). Septal spines in the frame of septa project at the inner edge in the axial space and produce a weak parietal papillose columella. Radial symmetry and bilateral symmetry following the calicular elongation. Endotheca made of numerous dissepiments. Synapticulae not observed. Epitheca s.l. present.
Calicular diameter: 17 to 20 mm – Number of septa: approximately 120 – Septal density: 4 to 7 per 2 mm.
REMARK
The original material described in Beauvais (1986) consists in a heterogeneous batch. The holotype belongs to the Stylophyllidae because of its septal structure. One of the paratypes (within the batch MNHN.F.A32021) seems to be a Proleptophyllia . None of the specimens shows the typical characters of the genus Epistreptophyllum Milaschewitsch, 1876 .
