My friend had us walking around the Rye Wetlands Conservancy in Rye, New York.  I saw this shell and wanted it for my own but was told it was wrong to take prizes from this natural setting.  I left it behind, of course.  But two days later, Hurricane Sandy happened and a storm surge of 9 to 14 feet washed over this area – am sure my shell was LONG GONE immediately.  I wonder where it landed next?  I am glad that it survives in my memory and on my website!
