Elea lamellosa is an extremely abundant bryo- zoan in the Coniacian-Santonian calcarenites of the Loire region, notably the Craie de Villedieu, and in approximately contemporaneous deposits in the Aquitaine Basin, for example at Saintes. It is the only bifoliate melicerititid to occur commonly in these beds, in which dendroid forms such as Meliceritites magnifica, M. ornata and M. tuberosa tend to dominate (Fig. 3). The foliaceous shape ('eschariform') of the colonies contrasts with most other bifoliate melicerititids which have strap-like branches ('adeoniform'). Although present in several species of Meliceritites and also in Semielea vieilbanci, no other species of Elea possess small eleozooids with inverted T-shaped apertures. These trifoliozooids are the principal means of distinguishing between E. lamellosa and the closely similar but stratigraphically younger E. pseudolamellosa (p. 30)..
