From Stage 9e at Ringerike, a British Wenlockian cystoid, Prunocystites fletcheri Forbes, is described and on this evidence it is suggested that most or all of Stage 9 is of Wenlockian age, and that the lowermost part of Stage 10 was deposited in Early Ludlovian and possibly Latest Wenlockian times.
