DESCRIPTION

Solitary, patellate corallum. Radial elements are exsert costosepta organized in 3 distinct size orders and apparently 5 distinct ontogenetic cycles (6+6+12+24+48 septa). They are straight, free, of montlivaltid structure. Endotheca made of rare peripheral dissepiments. An epitheca s.l. wraps the basis of the corallum.

Calicular diameter: 14.4 mm – Number of septa: 96 by extrapolation – Septal density: 5 per 2 mm.

SIMILARITIES AND DIFFERENCES

The differences with Montlivaltia sp. described from Moroccan Toarcian ( Vasseur 2018) is difficult to confirm because of the great intraspecific variability of the latter species and the uniqueness of the Pliensbachian specimen from Calvados. However, the specimen described herein shows quite higher septal densities and a more regular septal apparatus than the specimens from the Toarcian.
