Orthospirifer Lophophore Brachiopod Fossil

This fossil is a great example of the brachiopod lophophore feeding tubes preserved in a white quartz form. This brachiopod appears to be some sort of Orthospirifer. It was found in the Sellersburg Limestone that formed in the Middle Devonian Period (Eifelian).

Thanks to Mary Ann for letting me take some pictures of it.
