GEOGRAPHIC AND STRATIGRAPHIC RANGES. — Pliensbachian of May-sur-Orne ( Calvados , France).

DESCRIPTION

Solitary, subconical corallum. Radial elements are exsert, thin, subcompact, straight costosepta with trabecular, montlivaltid microstructure made of spaced carinae. No columella but a large and quite deep circular fossa. Endotheca made of tabular dissepiments at the periphery. We observed some vestiges of an epicostal epitheca s.l. that covered the external part of the corallum. Calicular diameter: 36 mm – Septal density:3 to 4 per 2 mm.

SIMILARITIES AND DIFFERENCES

Even if the species is based on one single specimen, it is distinct among species of the genus Montlivaltia because of the delicacy of septa and the large space between them and between carinae in one single septum.
