DESCRIPTION
Solitary corallum of various morphologies: tends to be cylindrical, ceratoid or subconical, circular to elliptic in outline. Radial elements are compact, free, straight or curved septa with smooth lateral faces. The inner edge is sometimes rhopaloid in depth. Septa show a lamellar mode of growth with successive deposits of sclerenchyme (as “glove fingers” according to Beauvais 1986), resulting in wedge-shaped septa characteristic of Archaeosmiliidae family. Endotheca sometimes observed, made of vesicular dissepiments in continuity with the wall and septa. Parathecal wall. An epitheca s.l. wraps the corallum. Calicular diameter: 11 to 26 mm – Number of septa: 12 to 20 – Septal density: 1 to 3 for 5 mm.
