In the "Winterized Mollusks" thread, Paul Monfils cites some interesting observations on mass mortality (death) of mollusks, which can often be of particular species. I'd like to hear from people who have witnessed such events, on land, sea, or freshwater. What species were involved in the mass mortality? What was the cause of death, if known? In what season or month did this occur? Andrew K. Rindsberg Geological Survey of Alabama Tuscaloosa, Alabama, USA
