Studies on some Elphidiidae (foraminifera) from the Miocene of Denmark

The three Elphidids examined, ?Elphidium ungeri (Reuss), Elphidiella minuta (Reuss) and Cribrononion heteroporum (Egger) are derived from the Lower and Middle Miocene formations of Denmark. They are shown to differ considerably from each other in distinct features diagnostic at the generic level.

The spiral cana ls are rather complicated in ?E. ungeri and C. heterroporum, which show a system af anastomosing canals connecting different parts of spiral canals, while the spiral canal in E. minuta is rather simple. The specimens referred to C. heteroporum show a distinct apertural cham berlet, which is decided to be of generic importance in the emended diagnosis of the genus Cribrononion.
