Upper Tertiary freshwater mussel fossils from the Coromandel Volcanic sequence

Abstract Measurements of thirty-seven impressions of upper Miocene and Pliocene Hyridella s.s. from Medland's Stream, Great Barrier Island, and Wainora Stream, Thames, suggest that they are members of several highly variable populations of the same species. Their similarity to Australian Tertiary fossils is noted and the effect of this record on ideas of the evolution of New Zealand freshwater mussels is discussed. Previous work on New Zealand freshwater mussels, fossil and recent, is summarised.
