Classification
Remarks
Alloiteau (1958, p. 195–196) described the solitary genus Sakalavicyathus and stated that it was characterized by a subceratoid corallum, compact and radially arranged costosepta, with granulated lateral sides, the presence of pali, that are variable in number and shape, the presence of a columella formed by a small number of trabeculae, thin endothecal dissepiments, and a parathecal-synapticulothecal wall with intercostal pores. However, re-examination of the holotype revealed that higher cycle septa frequently merged with lower cycle ones, that the trabecular columella was well-developed, and that costae were rather represented by a linear arrangement of coarse granules. Therefore, together with the above mentioned charatceristics, Sakalavicyathus Alloiteau is considered a junior synonymy of the genus Palaeopsammia (Baron-Szabo, 2008, p. 36, pl. 2, figs. 4a-b).
