Genus Placosmilia Milne Edwards & Haime,1848a Typespecies. Turbinolia cymbula Michelin, 1846, Santonian of France(Aude) (see Milne Edwards & Haime, 1848a).
Diagnosis.Colonial. Younger specimens flabellate, becoming meandroid in later ontogenetic stages. Budding intracalicinal, resulting in a single meandroid calicinal series. Costosepta compact, arranged bilaterally. Septal margins granular. Septal flanks often secondarily thickened which might cover granules and carinae. Endothecal dissepiments well-developed, occurring throughout the whole corallum. Columella lamellar, continuous or formed by irregularly occurring lamellar segments. Trabecular extensions of axial septal ends often fuse with columellar structures. Wall parathecal to septoparathecal. Multilamellar epithecal s.l.wall sometimes present.
Remarks.Te genus Placosmiliawas recently revised and reevaluated ( Baron-Szabo, 2014, p. 34–35, Pl. 24, Figs. 1–5; Pl. 25, Figs. 1–5; Pl. 26, Figs. 1–7).
