Abstract Shells of the freshwater mussel Hyridella menziesi from Taumutu, Lake Ellesmere, give a radiocarbon age of 748 ±41 years b.p. They indicate former higher-level lakeshores and date the formation of the most recent ridges. Their occurrence presents a problem because the lake is brackish at present, and because no freshwater mussels have been reported living in or near Lake Ellesmere.
