Columactinastraea anthonii sp. nov. (Scleractinia, Astrocoeniina), a new coral species from the Maastrichtian (Upper Cretaceous) of The Netherlands

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.
