Murray-Darling basin freshwater shells: riverine reservoir effect

We report ciirbon isotope measurements on pre-bomb museum samples of freshwater mussel shells collected alive from riverine locations in New South Wales. Australia. The calculated reservoir ages, rimglng from -60 to +112 years, are much smaller than those for Australian marine shells and not considered significant for the radiocarbon dating of Late Pleistocene freshwater shells from the Murray-Darling Ba,sin.
