RETEPORA UNDATA M'COY, 1844, TYPE SPECIES OF PHYLLOPORELLA FREDERIKS, 1916, A JUNIOR SYNONYM OF CHAINODICTYON FOERSTE, 1887: A PHYLLOPORINID BRYOZOAN FROM THE MISSISSIPPIAN OF IRELAND REDESCRIBED

Abstract

Abstract:Retepora undata M'Coy, 1844, from the Mississippian of Ireland is shown to be a phylloporinid bryozoan of the genus Chainodictyon Foerste, 1887. It forms reticulated zoaria of anastomosing branches with characteristic droplet-shaped fenestrules. The status of the genus Phylloporella Frederiks, 1916, which was originally named with two type species is here formalised through designation of Retepora undata M'Coy, 1844, as the type species. Phylloporella Frederiks, 1916, is a junior synonym of Chainodictyon, Foerste, 1887.
