Pterinea Pelecypod Fossil Fragment

This fossil appears to be a Pterinea brisa Hall (or Ambonychia (Pterinea) striaecostata McChesney 1869) pelecypod fossil found in the Silurian Waldron Shale of Clark County, Indiana. Learn more about it at my earlier blog posting from June 20, 2012.

Good timing Mike. I found a whole one of these on a fragment of Osgood shale as I was combing through boxes this weekend. Now I have an ID!
