Potamilus alatus: Pink Heelsplitter

Found this dead specimen a year or two ago while installing some equipment in a Cannon River tributary. I set it in my garage. Now doing a little looking at mussels here and there, and I got to thinking about this pink shell resting on a wooden shelf out there in the dark. So I cleaned it up a bit and brought it in to work so I could stare at something good now and then.

99% sure I have the specie right. Check the literature on it - some excerpts below from MN DNR's Mike Davis (public info). Dependent on the freshwater drum for reproduction (Google: mussel reproduction to check the cycle).
