Article: The ecology and stratigraphical distribution of the invertebrate fauna of the Great Estuarine Series
The invertebrate macrofauna of the Great Estuarine Series is reviewed, with special reference to the ecological inferences which can be drawn from it. Evidence from modern relatives, and from association with other fossils, is used to deduce the probable ecological preferences, especially of salinity, of each of the common species. The stratigraphical distribution of the fauna among the formations of the Series is comprehensively described for the first time. Unio andersoni sp. nov. is described and figured.
