DESCRIPTION
Solitary discoid coral, circular in outline, fixed to its substratum (bivalve shell in this case) by its lower face, which morphology seems to have been governed by physical constraints sustained by the organism: in longitudinal radial section, one side is more elevated and laterally packed than the opposite one. Septa pennular, perforate, straight, free or joined with continuous horizontal meniana on lateral faces. Distal edge ornamented with small regular teeth. Axial zone with a restricted fossa and probably trabecular projections of septa in depth. The lower face of the corallum is layered by an epitheca s.l. of unknown nature. Endotheca made of rare dissepiments in depth. Synapticulae abundant. No bilateral nor hexameral symmetry observed.
Calicular diameter: 19.3 mm – Septal density: 16 for 5 mm – Estimated number of septa> 136.
