Steve... Is there any difference in the arrangement of the teeth or even just how the hinge join lines up? The teeth in these both looked the same, one with a smooth periostracum, and then the downstream ones, with the typical large ridges on what I'm sure were Corbicula.

What I need to do is quit farting around and just take the danged things home (abandoned valves) without guilt and learn. I have 30 ways to rationalize this... Maybe I just need to put them down on paper and get a reference and get the stupid permit. <sigh>

BG thanks for the response. I'll be meeting up with JT next week at the Tippecanoe trip, and hope to "download" a bunch of his mussel knowledge. I think since I'll be making "fish" my profession here soon, I'll take up mussels as my "hobby" :)
