| A lectotype has been assigned for Placosmilia? robusta Umbgrove, 1925. This taxon, although fitting into the original diagnosis of Placosmilia, is not defined by the emended diagnosis of Alloiteau and later authors. Specimens from the Upper Maastrichtian of The Netherlands, that were formerly wrongly attributed to Galaxea fasciculata (Lamarck, 1816), a homonym of the extant species Galaxea fascicularis (Linnaeus, 1758), belong to Placocoenia macrophthalma (Goldfuss, 1826). The specimen depicted as P. macrophthalma by Umbgrove does not belong to this taxon and is placed in open nomenclature. |

| Only four cerioid species of scleractinian corals have been described from the Maastrichtian in its type area; the montlivaltiid Isastrea angulosa (Goldfuss, 1826), and the astrocoeniids Actinastrea goldfussi d’Orbigny, 1849, A. faujasi (Quenstedt, 1881) and Columastrea fallax Umbgrove, 1925. A lectotype is selected for the latter species. A new cerioid species, Columactinastraea anthonii sp. nov., is recorded from the middle part of the Meerssen Member (Maastricht Formation) at the ENCI Quarry, Zuid Limburg, The Netherlands. It is well-preserved and differs from other Columactinastraea species mainly by the relatively large diameter of its lumen. |
